Which of the following options correctly describe ways in which mountains can be formed?

A) Tectonic Plate Collision: When two tectonic plates collide, they can create mountains through the process of uplift and folding. Examples include the Himalayas and the Alps.

B) Volcanic Activity: Mountains can also be formed through volcanic activity. When magma rises to the surface and solidifies, it forms volcanic mountains. Examples include Mount Fuji in Japan and Mount Kilimanjaro in Tanzania.

C) Erosion and Weathering: Over time, erosion and weathering can shape existing landforms into mountains. This process involves the gradual wearing down of rocks and the deposition of sediment. Examples include the Appalachian Mountains in the United States.

D) Faulting: Mountains can be formed through faulting, which occurs when there is a break or fracture in the Earth's crust. The movement along the fault line can uplift and create mountains. Examples include the Sierra Nevada Mountains in California.

E) Isostatic Uplift: Isostatic uplift occurs when the Earth's crust adjusts to changes in the weight distribution, such as the melting of glaciers. This process can lead to the formation of mountains. Examples include the Scandinavian Mountains in Norway and Sweden.

F) None of the above.
