Hello there!,
Well a Igneous rock forms of course by the rate that it cools down in. If there is slow magma cooling then there will be larger crystals. Fast cooling leads to smaller crystals.
Hope I helped!
Stars with higher mass have much shorter life cycles because stars expand as they get older that is why the larger the star the older it is smaller stars are more dense with more energy
The answer is C. Energy is released
