Chocolate is a kind of food that many people like. It is sweet and delicious, with a strong and special taste, which is always irresistible. Even in many fairy tales, chocolate kingdom and chocolate castle often appear, which is enough to prove people's love for chocolate.
If there is really a chocolate hills in this world, I must especially want to find it and have a good time. However, this chocolate hill is not really a mountain made of chocolate, but a natural conical hill. However, although it can't really be full of food, its peculiar landscape can bring great visual enjoyment to people!
Chocolate hills is a natural wonder in the central part of Baohe Island, which consists of 1268 conical hills. The heights of these hills range from 40m to120m. From the air, they look like haystacks piled on the ground.
Every summer, these "haystacks" will dry up, and the hills will turn brown and look like rows of chocolates on the ground. And "chocolate hills", a mouth-watering name also comes from this.
The shapes and colors of these chocolate-like hills are already very eye-catching and can arouse people's beautiful reverie. And if we observe them carefully, we can also find a strange phenomenon, that is, it is difficult to find trees on the top of chocolate hill. There are no trees on this mountain except grass.
Maybe someone will guess, is it that the climate here is not suitable for trees to grow? Actually, it's not like this. Chocolate hills is located in the subtropical zone with a hot climate. Besides, it is close to the ocean and the air is very humid. In the rainy season every year, the precipitation is also very rich. This environment is actually conducive to the growth of plants. The most direct evidence is that there are not only thatched hills in chocolate hills, but also a large number of lush green trees, which is in sharp contrast with the bare hills.
Obviously, the climate and environment here are very suitable for plant growth, and the vegetation coverage rate in the surrounding areas is also very good. Why are there no trees on this chocolate mountain?
After exploration, geologists found that there was only a thin layer of residual soil on these hills, and hard limestone was under the residual soil. The roots of common plants are usually difficult to destroy the rock surface and penetrate deep into the rock. So only thatch can make a home on it. For tall plants like trees, it is difficult to grow on the top of the mountain because of the difficulty of rooting and the limited nutrition provided by residual soil. This is the strange phenomenon that there are no big trees on the top of the chocolate mountain.
However, some people think that the reason why trees can't grow on the top of the mountain is that the sea breeze here is too strong, and the trees on the top of the mountain are easily blown off by the wind, so they can't grow.
