Answer 1

The phrases that apply to metamorphic rock formation are:

• Form from existing rocks

• Form without melting

• Appear foliated or non-foliated

• Require heat and pressure to form

Step-by-step explanation:

Metamorphic rocks are formed from existing rocks that have been subjected to heat and pressure. This causes the minerals in the rocks to recrystallize and form new, more stable minerals. The process does not involve melting, and the resulting rocks can appear either foliated (layered) or non-foliated depending on the type of minerals present.

Metamorphic rocks do not form from liquid rock or from the process of deposition, which involves the accumulation of sediments to form sedimentary rocks.
