Here's why:
* Plate tectonics: Mountains are formed primarily through the movement and collision of Earth's tectonic plates. These plates are giant slabs of rock that make up the Earth's outer layer.
* Collision and Uplift: When two plates collide, the denser plate often subducts (slides) beneath the less dense plate. This process creates enormous pressure and heat, which can cause the overlying plate to fold, buckle, and uplift, forming mountains.
* Other Processes: While plate collisions are the most common way mountains form, other processes can also contribute, such as volcanic activity (like the Hawaiian Islands) or erosion by glaciers (creating jagged peaks and valleys).
Think of it like this: Mountains are not like giant bubbles rising from the ground. They are formed by the intense forces of plate tectonics, which push and fold the Earth's crust into towering peaks.
