Question

what type of plate boundary forms large mountain ranges such as the himalayas?

Explanation:

The problem is about plate boundaries and mountain formation, which falls under the subfield of Geology (a part of Natural Science, specifically Geography or Geology). Convergent plate boundaries, where two continental plates collide, cause the crust to crumple and form large mountain ranges like the Himalayas (formed by the collision of the Indian and Eurasian plates).

Answer:

Convergent plate boundary (specifically continental - continental convergent boundary)
