Plateaus are flat topped mountains with steep sides. They are formed by erupting volcanoes,erosion by water and glaciers. Plateaus can be formed by magma swelling up to lift rocks and the ground upwards to form a plateau. Plateaus can also be formed by erosion. The glaciers melt into water and the water eats away at the rock so after millions of years only a plateau is left.
