Question

Which of the following statements about the rock cycle is false?

1) Igneous rocks can be weathered to form sediment
2) Rocks typically first become metamorphosed before they can be melted to form magma
3) Metamorphic rocks cannot undergo weathering to form sediment
4) Heat from the interior of the Earth contributes to the rock cycle
5) The Earth is in a constant state of change

Answer 1

Metamorphic rocks can undergo weathering and form sediment.

Step-by-step explanation:

The false statement about the rock cycle is the following: Metamorphic rocks cannot undergo weathering to form sediment. In reality, all three types of rocks can undergo weathering and contribute to the formation of sediment. Igneous rocks can be weathered to form sediment, which can then be lithified into sedimentary rocks. Metamorphic rocks can also undergo weathering, breaking down into sediment that can form sedimentary rocks.
