GEOLOGY

Detailed explanation-1: -Mountains form where two continental plates collide. Since both plates have a similar thickness and weight, neither one will sink under the other. Instead, they crumple and fold until the rocks are forced up to form a mountain range. As the plates continue to collide, mountains will get taller and taller.

Detailed explanation-2: -Mountain Building-Fault-block Mountains When divergent plate motion occurs beneath a continental crust, rift structures and normal faults form. This continental rifting causes valleys floors to drop down along fault lines.

Detailed explanation-3: -Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collisional mountain range forms as the crust is compressed, crumpled, and thickened even more.

Detailed explanation-4: -Plate tectonics is a scientific theory that explains how major landforms are created as a result of Earth’s subterranean movements. The theory, which solidified in the 1960s, transformed the earth sciences by explaining many phenomena, including mountain building events, volcanoes, and earthquakes.
