Question

Which statement best describes the formation of metamorphic rocks?

Magma cools and crystallizes slowly beneath Earth’s surface.
Liquid lava erupts from a volcano and cools quickly at Earth’s surface.
Sand and gravel are deposited at the mouth of a river and, over time, form layers that solidify into rock.
Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure.

Answer 1

Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure.

Answer 2

Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure is the correct answer.

Step-by-step explanation:

• Metamorphic rocks are formed when the preexisting rocks are subjected to high pressure and heat in a method called metamorphism,

• Metamorphic rocks may be created by being buried below the Earth's surface,when subjected to high heat and high pressure.

• Metamorphic rocks are derived from igneous or sedimentary rocks.

• Examples of metamorphic rocks are schist, quartzite, marble, slate, gneiss, and anthracite.
• Thus Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure best describes the formation of metamorphic rocks.
