Tectonic Wonders: Earth's Geological Puzzles

What is a mid-ocean ridge?

• A single mountain peak formed by volcanic activity

• A deep trench in the ocean floor

• An underwater mountain range formed by plate tectonics

• A flat area on the ocean floor where new crust is not being created

In a subduction zone, what happens to the oceanic crust as it is forced beneath the continental crust?

• It becomes less dense and rises back to the surface

• It accumulates into large folds and forms mountains

• It melts and may contribute to volcanic activity

• It remains intact and slides under the continent without changing
