A clap of thunder and a lightning bolt occur from the same collision of molecules, but we hear the thunder after we see the lightning bolt because of the slower speed of sound.

Explanation:

Thunder and lightning happen from the same collision of molecules, but we hear thunder after seeing the lightning because of the slower speed of sound.

What happens is that light travels at a much greater speed than sound. While light travels at a speed of 299,792,458 meters per second (almost 300,000 km / s) in a vacuum, sound travels through the air at a speed of approximately 340 m / s.

In water, the speed of sound is higher (1,400 m / s), but remains much lower than the speed of light. Thus, the lightning of lightning is seen by our eyes before the sound of thunder reaches our ears.

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.
