The longest mountain range in the world is the Andes, which stretches for about 7,000 kilometers (4,300 miles) along the western edge of South America.

Is the crust thicker under the sea or a mountain range?

The crust is generally thicker under a mountain range compared to under the sea. This is because mountain ranges are formed by the collision of tectonic plates, which can result in the crust being pushed up and folded, leading to its thickening. In contrast, the crust under the ocean is thinner due to the process of seafloor spreading where new crust is constantly being created at mid-ocean ridges.
