GENERAL KNOWLEDGE

Detailed explanation-1: -The type of a landform formed by the massive rock movements or solidification of huge quantities of magma due to the plate tectonics is known as “structural landforms.” These landforms include volcanoes, rift valleys, fold mountains, and shields.

Detailed explanation-2: -Mountains, Plateaus and Plains are some major landforms of the Earth. Natural processes such as weathering, water, elevation, sinking, and erosion of the soil are constantly shaping the Earth’s surface. It doesn’t really happen overnight. In fact, it takes hundreds and thousands of years for us to notice these changes.

Detailed explanation-3: -Answer: (a) The major landforms are: mountains, plateaus and plains. A mountain is any natural elevation of the Earth’s surface. It is considerably higher than the surrounding area.

Detailed explanation-4: -Tectonic plate movement under Earth can create landforms by pushing up mountains and hills. Erosion by water and wind can wear down land and create landforms like valleys and canyons. Both processes happen over a long period of time, sometimes millions of years.
