GEOLOGY

Detailed explanation-1: -The thing that causes a change in the Earth’s landforms is plate tectonics. Tectonic plates are huge slabs of rock and underneath all of the world’s landmasses and seas. These plates move occasionally. These movements may be undetectable or may cause natural disasters such as earthquakes and volcanoes.

Detailed explanation-2: -Wind, water, and ice erode and shape the land. Volcanic activity and earthquakes alter the landscape in a dramatic and often violent manner. And on a much longer timescale, the movement of earth’s plates slowly reconfigures oceans and continents. Each one of these processes plays a role in the Arctic and Antarctica.

Detailed explanation-3: -Earthquakes, volcanoes, tsunamis and landslides are naturally occurring events that can rapidly change Earth’s surface.

Detailed explanation-4: -Weathering, erosion and deposition are processes that can wear a mountain down.

Detailed explanation-5: -Waves, wind, water, and ice shape and reshape the Earth’s land surface by eroding rock and solid in some areas and depositing them in other areas, sometimes in seasonal layers. Rock is composed of different combinations of minerals. Smaller rocks come from the breakage and weathering of bedrock and larger rocks.
