Question

1. How are metamorphic rocks formed?
and give example.​

Answer 1

Answer:

Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Conditions like these are found deep within the Earth or where tectonic plates meet.

Answer 2

Under heat and pressure,both igneous and sedimentary rocks transform into metamorphic rock. These metamorphic rocks get partially or wholly get changed in colour, texture,hardness and mineral composition from their igneous or sedimentary rock. This is how metamorphic rock are formed

Ex:

•granite is a igneous rock which changes into gneiss due to immense pressure

•sandstone is a sedimentary rock which changes to quartzite due to very high temperature
