The first law of thermodynamics states that

1. when a process converts energy from one form to another, some energy converts into heat, an unusable form of energy
2. energy can neither be created nor destroyed, but it can change from one form to another
3. energy flows through ecosystems without being recycled
4. most energy in ecosystems comes from the sun

Your answer would be; Energy can be changed from one form to another, but it cannot be created or destroyed.

igneous rocks which formed by the crystallization of magma at the surface of the earth called extrusive rocks. they are characterized by fine-grained textures because the rapid cooling at or near the surface did not provide enough time for large crystals to grow.
