An igneous rock has large red, black, and green crystals. how else can this rock be accurately described? fine texture cooled quickly intrusive origin created by lava

The best answer would be:

Intrusive

If you'd like to know more about this read on:

Intrusive igneous rocks are formed beneath the Earth, so they are formed from magma. (Not lava because lava is magma that has reached the surface of the Earth)

These types of rocks cool slowly which allows time for the formation of large crystals and accumulation of different other minerals. The texture is then coarse.

The opposite is called an extrusive igneous rocks, which are usually fine-grained because it cooled quickly from lava.

this could be newton#'s law of cooling. the cooling curve is exponential
