Question

briefly define mechanical metamorphism​

Answer 1

Explanation:

Metamorphism means the change in the structure of rocks. Mechanical weathering of a rock takes place when  rocks are broken down into small pieces due to the action of wind, water, heat and pressure.

Answer 2

Explanation:

$\huge \tt \: answer$

This is a mechanical Transformation in which texture of rocks is changed by crushing and rubbing processes associated with heat and compression created by mechanical action.Dynamic metamorphism, or cataclasis, results mainly from mechanical deformation with little long-term temperature change. Textures produced by such adjustments range from breccias composed of angular, shattered rock fragments to very fine-grained, granulated or powdered rocks with obvious foliation and lineation.

3 types of metamorphism

Three types of metamorphism exist: contact, dynamic, and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism.
