The mountains of the Basin and Range Province formed when

• crust melted.

• two continents collided.

• blocks of rocks moved at faults.

NGSS.MS-ESS2-2

What role does subduction play in Earth's rock cycle?

• It causes isostasy.

• It causes erosion at the surface.

• It causes cementation of sediment.

• It causes surface rocks to be pushed deep into the Earth.
