The word igneous comes from the Latin word for fire. However, the name is inaccurate. The rocks are not created with flames. Instead, they are created when magma cools and hardens. Magma is hot molten rock found deep in the earth. Igneous rock is either intrusive or extrusive. It is intrusive when it forms inside the earth's crust. It is extrusive when it is formed above the earth's surface.
Select the statement that explains how igneous rock is formed.
Question 9 options:
Molten rock found inside the earth cools and hardens.
Existing rocks are heated in fire until they melt.
Ash from volcanos falls and compresses into layers of rock.
Pressure below the surface forces rocks to smash together.
