If the Earth had no mountains, the land would become mostly flat everywhere. Mountains help in stopping winds and causing rainfall. Without mountains, winds would move freely and many places would get less rain. Rivers usually begin from mountains, so rivers would become slower and less powerful. Mountains also create valleys, hills, and plateaus and provide homes for many plants and animals. Without mountains, the Earth would lose much of its natural beauty and biodiversity. The landscape would look almost the same everywhere.

Short Note
What If Earth Had No Mountains ?
If Earth had no mountains, the land would become completely flat. Mountains play an important role in controlling weather by blocking winds and causing rainfall. Without them, weather patterns would change and many regions would receive less rain. Rivers, which usually originate from mountains, would flow more slowly due to lack of slope. Also, there would be less land diversity, as mountains create valleys, hills, and plateaus.
