Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
How do most mountains form?
A
Continents collide and fold up on each other
B
Earth is shrinking and the crust wrinkles up
C
Ocean plates diverge and fold up on each other
D
Gravity from the moon pulls sections of the Earth up
Explanation: 

Detailed explanation-1: -Fold mountains are created where two or more of Earth’s tectonic plates are pushed together. At these colliding, compressing boundaries, rocks and debris are warped and folded into rocky outcrops, hills, mountains, and entire mountain ranges. Fold mountains are created through a process called orogeny.

Detailed explanation-2: -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-3: -These are created where two or more of Earth’s tectonic plates are pushed together. Block Mountains: Block Mountains are formed when two tectonic plates move away from each other causing cracks on the surface of the Earth. Volcanic mountains: are formed as a result of volcanic activities on the surface of the Earth.

Detailed explanation-4: -At a destructive plate boundary, the oceanic plate is subducted beneath the continental one. The molten material then rises to the surface to form volcanoes, either in an island arc (e.g. the West Indies) or on the continental landmass (e.g. the volcanoes of the Andes). In both cases, the Fold Mountains can be formed.

Detailed explanation-5: -How Are Mountains Formed? The world’s tallest mountain ranges form when pieces of Earth’s crust-called plates-smash against each other in a process called plate tectonics, and buckle up like the hood of a car in a head-on collision.
