Answer 2

Answer:

1.Plains are one of the major landforms on earth, where they are present on all continents, and would cover more than one-third of the world's land area. Plains may have been formed from flowing lava, deposited by water, ice, wind, or formed by erosion by these agents from hills and mountains.

2. Plateaus are built over millions of years as pieces of Earth's crust smash into each other, melt, and gurgle back toward the surface. The highest and biggest plateau on Earth, the Tibetan Plateau in East Asia, resulted from a collision between two tectonic plates about 55 million years ago.
