Metamorphic rocks

Explanation:

The word metamorphic comes from Greek and it means "To Change Form". Metamorphic rocks are formed from parent rock with the change of pressure and heat. The original rock (protolith) is subjected to heat (temperatures greater than 150 to 200 °C) and pressure (more than 100 megapascals ), causing profound physical or chemical change. Metamorphic rocks make up a large part of the Earth's crust and form 12% of the Earth's land surface.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
