GEOLOGY

Detailed explanation-1: -Sometimes an entire ocean closes as tectonic plates converge, causing blocks of thick continental crust to collide. A collisional mountain range forms as the crust is compressed, crumpled, and thickened even more.

Detailed explanation-2: -Each of these types of plate boundaries is associated with different geological features. Typically, a convergent plate boundary-such as the one between the Indian Plate and the Eurasian Plate-forms towering mountain ranges, like the Himalaya, as Earth’s crust is crumpled and pushed upward.

Detailed explanation-3: -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-4: -Continent-continent convergence creates some of the world’s largest mountains ranges. The Himalayas (Figure below) are the world’s tallest mountains. They are forming as two continents collide.

Detailed explanation-5: -Most divergent plate boundaries are underwater and form submarine mountain ranges called oceanic spreading ridges. While the process of forming these mountain ranges is volcanic, volcanoes and earthquakes along oceanic spreading ridges are not as violent as they are at convergent plate boundaries.
