When an organic compost pile is built correctly (sufficiently large, slightly moist, and containing a variety of organic material), it tends to get hot. which of the following best explains why a compost pile gets hot? solar energy hitting the pile causes photosynthetic microorganisms in the pile to begin working and releasing the stored energy as heat. water molecules within the compost pile spontaneously break down and release their energy as heat. the decomposers are breaking down energy-containing organic molecules for their own use and some of the energy escapes as heat. the decomposers are constantly moving around within the compost pile and the friction of their motion heats up the pile.

I think it is D or maybe C.

Explanation:

But like the other person who answered I am not sure as well. Hope Thos Helps:)

answer and explanation;

volcanic rocks are igneous rocks which form from lava, molten rock which has been thrust out of a volcano onto the surface of a rocky body such as an asteroid, planet, or dwarf planet.  

plutonic rocks are igneous rocks which form from subterranean chambers of molten rock or magma. plutonic rocks make up the base of continental crust as well as oceanic crust. their slow rate of formation causes them to be coarse grained since there is plenty of time for large crystals to form before the magma solidifies into rock.

the textural difference is that plutonic rocks are more coarse grained than volcanic rocks. plutonic rocks are coarse grained while volcanic are fine grained ; glassey or fragmental. since fine and coarse are adjectives the decision as to whether a rock is fine or coarse grained is generally made on the bases of whether or not the individual crystals can be seen in most if the rock.

there's no big difference.

explanation:

the only little different between a rabbit and bunny is just that bunnies are much smaller than rabbits. bunnies are basically baby rabbits.
