During the rock cycle, sedimentary rocks are returned to the Earth's interior and become metamorphic rocks through metamorphism. Metamorphic rocks can then move even deeper into the Earth's interior and melt into magma. What phenomenon is responsible for moving sedimentary and metamorphic rock into the Earth's interior?

Question

infiltration

condensation

the carbon cycle

plate tectonics

Answer 1

Plate tectonics are responsible for moving sedimentary and metamorphic rock into the Earth's interior. When tectonic plates converge or subduct, rocks on the surface can be pushed down into the mantle. This process is called subduction, and it can create intense heat and pressure that can transform rocks from one type to another, creating metamorphic rocks. Eventually, these rocks can be melted and mixed with other materials to form magma.
