Igneous Rock – formed from melted lava and magma. These rocks are all
made from magma but can look very different, this is because some cool fast
and some cool slowly. The slower a rock cools, the more minerals it forms.
Ex. Obsidian – smooth rock, glassy, cooled very quickly
Basalt – smooth rock with few mineral grains, cooled fairly quickly
Granite – rough rock that cooled very slowly because of all the
mineral grains in it (hint: grains = granite)

Sedimentary Rock – Formed from layers of settled rock. When rocks erode,
they get washed down rivers and streams, as they settle, layers form. Each
layer builds on one another and rocks are formed. It is like a bunch of little
rocks get cemented together to form new rocks, like your driveway!)
(hint: settled = sedimentary) Ex. Sandstone. Sometimes once living things
can settle in these layers, this is what creates fossils. Fossils are sedimentary.

Metamorphic Rock – A rock that has been changed (morphed) by heat and
pressure. These rocks are found deep in the earth. These rocks are very
heavy and solid because they have been densely packed together. The
mineral grains are flattened and spread out. Example: marble.

Fossil Fuels – Once living things may settle in the earth. They had stored
energy from the sun. This mixture of plant and animal remains gets layered
deep in the earth. We can dig deep in the earth to get these fossil fuels to
give many things energy like cars, trains, power plants, and airplanes!

Nonrenewable resources - Resources that cannot be made new again.
These can only be used once. When we use fossil fuels, we burn them. Once
they are burned, they are gone forever.
