Question

which statement best describes how igneous rocks are formed?
molten material in the earth cools and hardens to form igneous rocks.
layers of dirt and other rocks are pressed together to form igneous rocks.
elements in the earth form igneous solids with crystals.
wind erodes mountains into small igneous rocks.

Explanation:

Igneous rocks are formed from the cooling and solidification of molten material (magma or lava). The first option correctly describes this process. The second option describes sedimentary - rock formation, the third option is a general and inaccurate description, and the fourth option describes an erosional process related to weathering, not igneous - rock formation.

Answer:

Molten material in the earth cools and hardens to form igneous rocks.
