GEOLOGY

Detailed explanation-1: -This immense mountain range began to form between 40 and 50 million years ago, when two large landmasses, India and Eurasia, driven by plate movement, collided. Because both these continental landmasses have about the same rock density, one plate could not be subducted under the other.

Detailed explanation-2: -The Alps in Europe and the Himalayas are both fold mountains. The Himalayas were created millions of years ago when the Eurasian plate collided with the Indo-Australian plate.

Detailed explanation-3: -Deep ocean trenches, volcanoes, island arcs, submarine mountain ranges, and fault lines are examples of features that can form along plate tectonic boundaries.

Detailed explanation-4: -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.
