Question

Which of the following best describes an igneous rock that formed from quickly cooling lava?

Answer 1

I believe foliated is the correct answer as igneous rocks must form from molten magma/lava

Answer 2

Answer:

Fine grained

Explanation:

Fine grained is an igneous rock that is formed from quickly cooling lava, it is a kind of rock that has little grains that are less than 2 mm long, for this the grain is not visible to the naked eye, the grain on the igneous rock are dependant on the speed on which the lava is cooled, slow cooling allows for larger crystals and grains, while faster cooling creates smaller crystals and grains.
