Here are the descriptions of the mountain forming processes:

a) This picture shows volcanic mountain formation. Magma rises from beneath the Earth's surface and erupts as lava, ash, and rock fragments. These materials accumulate around the vent over time, building up a cone-shaped mountain.

b) This picture illustrates fault-block mountain formation. Tectonic forces cause the Earth's crust to fracture along faults. Blocks of land are then uplifted or tilted along these fault lines, creating mountains with steep, often straight sides.
