True or false: Igneous rocks are useful as building materials because the interlocking grain textures help to give them strength, and many of the minerals found in them are resistant to weathering.

• False

Extrusive igneous rocks generally have small mineral grains because

• the minerals in extrusive rocks do not form crystals under any condition.

• there is too much water in the magma.

• they cool quickly.

• they cool slowly.
