Answer 1

Thermal metamorphism is the term used to describe metamorphism due to heat alone, without differential stress.

Step-by-step explanation:

Thermal metamorphism occurs when a rock is subjected to high temperatures, causing the minerals within the rock to undergo recrystallization. The end result is a new metamorphic rock with altered mineral composition and texture.
