Analysis:
How did this mountain come into being? Jinyi said that mountains are made of stone; Colin said that the mountain was formed by lava from volcanic eruption; Zhuo said that mountains are made of stone.
Are they right? You will know after reading the following story.
Mother Earth has seven sons. Their names are Asia-Europe plate, Africa plate, North America plate, South America plate, Pacific plate, India plate and Antarctica plate.
Brothers are lively and active, always walking around or colliding with each other. One day, the naughty Indian plate wanted to play with the Asian-European plate in the north, but the Asian-European plate not only ignored it, but also annoyed it. The Indian plate is angry. It continued to move northward and slammed into the Eurasian plate.
There are many reasons for the formation of mountains, some are caused by volcanic eruption and magma accumulation, and some are caused by the compression of the earth. After a long time, some places are convex and some places are concave. The convex places form mountains and the concave places become basins.
