question 1: excuse me, what's the difference between the sea and the ocean? The difference between the sea and the ocean lies mainly in the depth.

the average depth of the ocean is about 4111 meters, and the deepest part is more than 11111 meters.

The sea is much shallower. For example, the average depth of the Bohai Sea is 18m, and the maximum depth is 71m. The average depth of the Yellow Sea is two or three hundred meters. The South China Sea is special, with an average water depth of about 1,111 meters and a maximum water depth of about 5,111 meters (this data is not clearly remembered), which is also the reason why China's first ocean drilling was carried out in the South China Sea (because the crust of the South China Sea is closer to the ocean crust, while the Bohai Sea, the East China Sea and the Yellow Sea are all close to the continental crust, and the voyage of this drilling is ODP184, and the chief scientist is Academician Wang Pinxian from the School of Oceanography of Tongji University. If you are interested, you can check it out).

Of course, the division of sea land is also related to the contact of marginal land.

12. Use paper on both sides

13. Sort garbage into boxes as far as possible

14. Turn off the lights at hand and save electricity

15. Advocate walking, cycling and taking buses as much as possible.

Question 3: In order to prevent the world climate from getting worse, advocate that everyone should What does not conform to the green life is that (a) the waste batteries after use will be concentrated and treated in a unified way, which will reduce the environmental pollution, heavy metal pollution, soil pollution, etc., and A is wrong; B, don't use disposable products, such as disposable lunch boxes, chopsticks, plastic bags, etc., which can reduce white pollution and meet the requirements of green living. B Wrong; C, driving a private car with parents to travel to the seaside during holidays, the content of carbon monoxide discharged from automobile exhaust is the highest, which will pollute the environment and meet the requirements of green life. C is correct; D, collect the paper that can still be written in order to continue to use it, which is an economical behavior and meets the requirements of green life. D is wrong. Therefore, choose: C

Question 4: Proposal on "Green environmental protection, start with me" "Green environmental protection, start with me"

In the early spring of 2118, 15 provinces, municipalities and autonomous regions in southern China were successively hit by snowstorms. Once again, nature cruelly tells us that environmental protection is urgent! It is urgent to build a national economic system with low input, high output, low consumption, less emissions and recycling and a resource-saving and environment-friendly society!

Of course, environmental protection cannot be separated from scientific and technological progress. With the continuous development of science and technology, we look forward to popularizing solar energy, hydropower, tidal energy and wind power in the near future; The most extensive and full use of natural gas; Try to make seawater desalination possible; A new generation of energy-saving electric light sources has stepped onto a new level; A new generation of building materials, which are durable, resistant to temperature and noise, resistant to corrosion and deformation, free from dust and radiation, will also benefit mankind.

Therefore, in order to make our sky bluer and our water cleaner, to firmly establish students' new ideas, new morals and new fashions in environmental protection, and to protect our beautiful home, and to welcome the 2118 Green Olympics-People's Olympics-Science and Technology Olympics, On the occasion of the first Science and Technology Culture Festival of Yucai Middle School and the establishment of a national-level green school, the student union of our school issued an initiative to all teachers and students: start from me, start from small things, start from ourselves, start from classes, dormitories and personal families, and bring all aspects of daily life and work into the track of environmental protection civilization, science, health and beauty. Understand and act mainly from the following aspects:

1. Saving is a virtue: saving every kilowatt hour. Turn off the lights when the last person leaves the classroom, conference room and dormitory. Students should consciously form a good habit of using air conditioners reasonably. Save every drop of water. When using water, turn the tap down as much as possible. Close it after use. If water leakage is found, actively notify the school education service department to repair it in time. The air-conditioned water in the dormitory can be used to wash the balcony floor. Save every grain of rice. Eat as much as you want, and try not to leave any food. It is a "crime" to waste food. Save every piece of paper. Use textbooks, exercise books and draft paper reasonably. Make the best use of everything and don't throw it anywhere.

2. Reuse of waste materials: All recyclable materials, such as waste paper, waste plastics, waste batteries, waste metals, etc., should be classified and recycled as far as possible to realize recycling of resources, thus saving resources and reducing garbage pollution. Therefore, it is suggested that all classes and dormitories should set up recycling bins for waste resources ..... When the recovered funds are accumulated, activities such as sports, fitness, art and science can be carried out.

.

There is morality in protecting the environment: put garbage into the box and don't throw it around; Take good care of greening and don't trample on the lawn. Everyone who cultivates talents

is the master of cultivating talents,

should be ashamed of littering,

can actively fight against uncivilized phenomena and

*** create

a clean and beautiful campus environment.

4

. Study hard, master the concepts and knowledge of modern science and technology and advanced culture, and learn to master the knowledge and technology about environmental protection

;

We should fully understand the seriousness of the current national, local and global environmental problems,

raise the awareness of protecting people's

kind of * * * homes,

through continuous study and hard work,

aspire to be a new century educator who is beneficial to the earth's environment,

beneficial to human beings and

sustainable development.

Dear students,

I hope that the above initiatives will strengthen our determination to bid farewell to green civilization,

not only can we learn from ourselves, but also can convey the healthy concept of green, harmonious and caring in the new century to all parties in the whole society, so that everyone can know it and do it

Question 5: Will XP give full play to the hardware performance than 98, so as to make the game run more smoothly? As a system that has been in service for more than ten years, it has ushered in its own home. Now, netizens all over the world can't help but be in awe of this system that has existed tenaciously in microsoft for more than ten years. Only by constantly exploring, trying and innovating can the system run more humanized. This point is that XP can't compare with 7 and 8.1.

question 6: carry out the propaganda of green and low-carbon life (write a few low-carbon suggestions and explain the reasons). Low-carbon life is indeed a rational lifestyle. In fact, before the industrial civilized society, even decades ago, we lived a low-carbon life, but the promotion of industrialization and urbanization quickly pushed human life to a high-carbon life. Of course, a high-carbon life cannot be sustained. So how can we achieve energy conservation and emission reduction and a low-carbon life on the basis of maintaining modern living standards? In fact, low-carbon life is an attitude, not an ability, for us ordinary people. We should actively advocate and practice low-carbon life, pay attention to saving electricity, oil and solar terms, and start from scratch. In addition to planting trees, some people buy goods with short transportation mileage. Some people insist on climbing stairs, some of which are interesting, while others are inevitably troublesome. Now let's talk about clothing, food, housing, transportation and economic activities. The first is "clothing". Everyone knows that young people like to wear jeans. In fact, jeans are the least "low-carbon". As far as the processing of denim is concerned, it not only consumes a lot of water and electricity to polish, but also extracts various chemical dyes with high carbon emission, which has a certain degree of * * * on the skin and is easy to cause allergic dermatitis, causing itching, pain, redness or blisters. In addition, chemical fiber fabric clothes have poor air permeability and hygroscopicity, which affects sweat evaporation and skin breathing, and is also easy to absorb dust in the air. Therefore, we try to choose less chemical fiber products as close-fitting clothes to wear. In addition, in the choice of fabrics, we may wish to choose some "low-carbon" materials, such as cotton, linen, silk and other natural fabrics, and try to avoid choosing clothing with chemical fiber texture. The second is "food". As we all know, pork and muscle are produced by consuming food on a large scale. Every year, China consumes more than half of the proportion of pork and chicken in the world, while producing a catty of pork or chicken consumes more than five times the food. If everyone goes to eat pork and chicken, it will hinder the development of this industry, which is actually a completely wrong route. 71% of the development of animal husbandry abroad is herbivorous animals, not food-eating animals. Therefore, the choice of meat in life should be mainly herbivorous animals, such as cattle and sheep, plus some fruits and vegetables, and don't eat too much meat transformed from grain. To sum up, we should achieve a balanced diet and change the habit of emphasizing meat; Eat less junk food and eat more vegetables and fruits. The third is "living". We should try to live in residential buildings, which are small in area and have many walls, so that the walls of one family can also transfer heat and make the room warmer. If you live in a villa, all sides are ventilated, so the energy consumption of a villa is very large. In addition, in the use of glass in the house, double-layer glass should be used as much as possible, or a one-way radiation film should be attached to the glass to prevent the light from reflecting and spreading to the outside quickly, because the heat insulation layer of the house is done well, which is equivalent to saving half of the energy supply. In terms of house decoration, most of the decoration materials still have different amounts of harmful chemicals. Too many decoration materials lead to the comprehensive concentration of pollution, which is difficult to dissipate for a long time. Moreover, energy is needed to process materials. In the era of low carbon, we should choose the appropriate apartment according to the number of family members and reduce the amount of water and electricity, which not only reduces the emission of carbon dioxide, but also saves money. Interior decoration should be based on the principle of simplicity, natural ventilation and lighting, and should not be over-decorated. Put more green plants in the house to absorb carbon dioxide, make oxygen, adjust the air and eliminate odor. The fourth is "line". If you use a private car, a private car itself weighs one or two tons, plus the heat loss of the engine. Even if there is no car for five people, 15% of the good energy of a car will be really utilized, and most of it will be lost. Therefore, it is a real waste and a huge crime for a person to drive out. Therefore, in our daily life, we should walk more, take fewer cars and climb stairs as much as possible, which can not only exercise, but also help to reduce carbon. Long-distance office workers should try to choose cars with low fuel consumption and more environmental protection, and take public transportation. Walking to work, on the other hand, can keep fit, enhance heart and lung function, improve blood circulation, enhance daily appetite, prevent cervical diseases, strengthen bones, avoid osteoporosis, exercise two arches, and prevent venous thrombosis. In addition, exercise should choose natural and healthy outdoor exercise instead of relying on electric fitness equipment; Should be carried out with moderate intensity, so as not to feel laborious. This way, carbon reduction and health care can be described as killing two birds with one stone. The fifth is economic activities. Traditional firewood and cookstoves are still used in many areas of our country. Burning straw with dried cow dung as fuel in southern Gansu wastes a lot of energy and resources, which is not conducive to the development of low carbon ..... >; >

question 7: green environmental protection, low carbon emission reduction and green living

June 5th is the annual World Environment Day. The theme of this year's World Environment Day in China is "Low carbon emission reduction? "Green Life" aims to advocate the public to practice green consumption, actively promote the construction of ecological civilization, and strive to achieve clean, safe, green and sustainable development.

With the continuous rise and development of modern China, our country's economy has gradually become stronger, and our people's living standards have been greatly improved. However, in the process of economic development, there are also many problems in our country, the most fatal of which is our environmental protection, which has seriously affected the continued development of our country. In order to help people know more about environmental protection, let people pay more attention to environmental protection in their lives, and form good habits of environmental protection, it is of great help to our country.

I learned about the so-called "low-carbon life" through the training on environmental protection some time ago. It is to minimize the energy consumed in daily life and schedule, so as to reduce carbon dioxide emissions. Low-carbon life is a life attitude for us ordinary people. It has also become a new way for people to push the trend. It gives us a question of whether we are willing to create a low-carbon life with everyone. We should actively advocate and practice a low-carbon life, starting from the little things around us.

1. Turn off the computer in time

Statistics show that 75% of the electricity in the home is spent on keeping the TV, computer and stereo on standby. On average, a desktop computer consumes 61 to 251 watts a day. If a computer is used for 4 hours every day and turned off at other times, it can save about 511 yuan RMB every year and reduce 83% of carbon dioxide emissions.

2. Take more buses

Carbon dioxide produced by traffic accounts for more than 31% of greenhouse gas emissions. One of the best ways to reduce such emissions is to take buses. According to the American Public Transportation Federation, public transportation saves nearly 5.3 billion liters of natural gas every year, which means that 1.5 million tons of carbon dioxide emissions can be reduced.

3. Choose a small house

People yearn for a big house, but the big house will increase carbon emissions invisibly and need more energy for heating and cooling. Take heating supply as an example, the big house needs to consume a lot of energy to maintain the temperature. The bigger the house, the greater the impact on the environment. At present, every household in the United States emits an average of 18 tons of greenhouse gases every year, and consumes a lot of fuel and non-renewable energy.

4. Open a window

We emit about 25 tons of carbon dioxide per capita every year. How can we reduce this figure? There are some simple and effective methods: open a window to replace indoor air conditioning; When using air conditioning in summer, the temperature is slightly raised by several degrees. Statistics show that as long as everyone turns up the air conditioner by one degree, the country can save 3.3 billion kWh of electricity every year.

5. Bring your own shopping bags

More than 511 billion plastic bags are consumed worldwide every year, of which less than 3% can be recycled. Plastic bags are all made of polyethylene, and it takes thousands of years to realize biological degradation after burial, and during this period,
