With an area of 1,964,375 square kilometers, Mexico is the third largest country in Latin America, located in the south of North America and the northwest end of Latin America. It is the only place for land transportation in South America and North America, and is known as the "land bridge". It borders the United States to the north, Guatemala and Belize to the south, the Gulf of Mexico and the Caribbean to the east, and the Pacific Ocean and the Gulf of California to the west. The coastline is 11,122 kilometers long. Among them, the Pacific coast is 7828 kilometers, and the Gulf of Mexico and the Caribbean coast are 3294 kilometers. It has an exclusive economic zone of 3 million square kilometers and a continental shelf of 358,000 square kilometers. The famous Tewantepec isthmus connects North America and Central America. The satellite map of Mexico covers about 5/6 of the country's plateau and mountains. Mexico Plateau is in the middle, flanked by East and West Madre Mountains, to the south by Neovolcanic Mountains and South Madre Mountains, to the southeast by the flat Yucatan Peninsula, with many long and narrow coastal plains. Orisaba volcano, the highest peak in China, is 5700 meters above sea level. The main rivers are bravo river, Balsas River and Yakimo River. Lakes are mostly distributed in the intermountain basins of the central plateau, and the largest is Chapala Lake, with an area of 1,109 square kilometers. Mexico's climate is complex and diverse. The coastal and southeastern plains have a tropical climate with an average annual temperature of 25-27.7℃. The climate in the Mexican plateau is mild all year round, with 24℃ in the intermountain basin and 17℃ in the higher terrain. Northwest China has a continental climate. Most areas are divided into two seasons: drought and rain, and the rainy season concentrates 75% of the annual precipitation. The average annual precipitation is less than 250 mm in the northwest, 750-1000 mm in the mainland, and 1000-2000 mm in the central part of the Gulf Coast and the southern part of the Pacific Coast. Because the territory of Mexico is mostly plateau terrain, there is no severe cold in winter, no heat in summer, evergreen trees in all seasons, and the natural conditions are extremely superior, so it is known as the "Pearl of the Plateau".
