📘 Why are the Himalayas still rising and wearing away?

Stand in the Himalayan foothills. The mountains are still rising, India keeps pushing north beneath Asia, and rain and ice wear the range down. The surprise is that both can operate together.

What you’ll learn

  1. India arrives at AsiaExplain India’s journey and collision with Eurasia.Buoyant continents collided and the boundary remains active.
  2. A thick crust makes high groundDistinguish crustal thickening, elevation, uplift and exhumation.The collision brings deep rocks upward across a broad high plateau.
  3. Rivers and glaciers take it apartExplain erosion and isostatic response.The range loses rock as it rises, and that loss can expose and rebound crust.
  4. Earthquakes reveal the locked boundaryConnect convergence to faults, earthquakes and hazard.The building boundary stores strain and releases it through earthquakes.

Questions this course answers

Why did the collision build mountains?

Continental crust resists deep subduction, so convergence is accommodated by shortening and uplift.

Match each term to its meaning.

The terms use different objects and reference frames.

How can erosion contribute to uplift without being the main engine?

The processes interact but are not interchangeable.

Order the earthquake cycle.

A locked fault stores strain while plates keep moving.
