Question

Which phrases apply to metamorphic rock formation? Check all that apply.

form from existing rocks

form without melting

appear foliated or non-foliated

form from liquid rock

form from deposition

require heat and pressure to form

Answer 1

Metamorphic rocks form from existing rocks under the influence of heat and pressure, without melting. They exhibit textures that are either foliated or non-foliated, and they are distinct from igneous and sedimentary rocks.

Step-by-step explanation:

The phrases that apply to metamorphic rock formation include the following:

• Form from existing rocks
• Form without melting
• Appear foliated or non-foliated
• Require heat and pressure to form

Metamorphic rocks are rocks that have been transformed from pre-existing rocks under the influence of high temperature and pressure. They do not form from liquid rock; that describes igneous rocks. They also do not form through the process of deposition, which is associated with sedimentary rocks. Metamorphic rocks may exhibit a foliated texture, where the minerals are aligned and layered, or a non-foliated texture, where minerals do not show any preferred alignment.
