• Himalayan Mountains in India

• Mt. Fuji in Japan

• Mt. Kilimanjaro in East Africa

The Himalayas formed as a result of _______.

• an ocean-continent convergence

• a continent-continent convergence

• an ocean-ocean convergence

• a hot spot

An identifying characteristic of convergent boundaries is _______.

• rift valleys.

• trenches

• seamounts and atolls

• black smokers

Volcanoes form above subduction zones because _______.

• water carried down by the subducting plate triggers the melting of rock that forces it's way up to the surface forming volcanoes

• the asthenosphere is pushed up by the subducting lithosphere and rises to the surface to form volcanoes

• the lithosphere thickens above the subducting lithosphere and causes volcanoes to form

• the subducting lithosphere melts as it descends and the magma descends deeper into the core

The San Andreas Fault zone in California is an example of _______.

• an ocean-continent collision

• a continental rift

• a divergent plate boundary

• a transform plate boundary
