Did you know rocks are the nonliving
solid material of the Earth?
Geologists use many different tools.
Hammers are used to separate
rocks and look at the different
layers.
A magnifying glass or a microscope is
used by a geologist to closely observe
properties of rocks and minerals.

Did you know rocks are the nonliving

Some rocks are formed from lava
coming out of an erupting volcano.
When the lava cools and hardens, it
separates and forms basalt, tuff, or
scoria.

Basalt is formed when
lava that has erupted
from a volcano cools and
hardens. A basalt rock is
gray and smooth.
Tuff is formed from the
ash created when a
volcano erupts. Tuff is
white, soft, and dusty.
Scoria is formed from the
bubbly top of lava. Scoria is
red and rough. It usually
has holes in it.

Another way rocks are formed is by
erosion. Erosion is when the wind, the
rain, and the sun break away the earth’s
surface and make rocks over time.
