Question

State the chief characteristics of metamorphic rocks.

Answer 1

1. They are harder and more compact than their original form.

2. Most of them are impermeable; they do not allow water to percolate through them.

3. They do not have fossils because fossils in sedimentary rocks are destroyed during metamorphism.

4. They are formed due to a change in texture and composition of pre-existing rocks.

5. New minerals are formed during the process of metamorphism.
