The Himalaya mountain range stretches about 2,400 km from Tibet into Pakistan. It began forming when the Indian plate collided with the Eurasian plate. The pressure of the colliding plates forced the crust upward, folding, bending, and twisting rock. The Indian plate still moves north at a rate of about 5 cm/year, which is faster than your fingernails grow. Some mountains in the Himalayas lift up at a rate of 10 mm/year 1. At which type of plate boundary did the Himalayas form?​

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.Mar. 9, 2015

Earth's crust

Explanation:

The lithosphere is the rigid outer part of the earth, consisting of the crust and upper mantle. It is the, rigid, rocky outer layer of the Earth, consisting of the crust and the solid outermost layer of the upper mantle. It extends to a depth of about 60 miles (100 km). It is the outer part of the solid earth composed of rock essentially like that exposed at the surface, consisting of the crust and outermost layer of the mantle.

We can also look at it as the solid part of the earth on which plants grow and animals survive. It contains all the rock formations that bear the various minerals found on earth.

The lithosphere is composed of both the crust and the portion of the upper mantle that behaves as a brittle, rigid solid.
