Igneous
Rocks
Do you know how they are
formed?
Watch to see if you can figure out
how igneous rocks form.
Did you figure it out?
Igneous rocks are called fire rocks and are
formed either underground or above ground.
Underground, they are formed when the
melted rock, called magma, deep within
the earth becomes trapped in small
pockets. As these pockets of magma
cool slowly underground, the magma
becomes igneous rocks.
Igneous rocks are also formed when
volcanoes erupt, casing the magma to
rise above the earth's surface. When
magma appears above the earth, it is
called lava. Igneous rocks are formed as
the lava cools above ground.
Review:

underground or _________.
