i hope u find it very educationally

1. LESSON 3:
Rocks

2. ROCKS
-are naturally formed solid made up of one or
more minerals.
-all rocks on or below Earth's surface belong
to one of three groups. Depending on how
they are formed, sedimentary rocks can be
igneous, metamorphic, or sedimentary.

Types of Rocks

4. Igneous RockIgneous Rock
The word igneous is derived from a
Latin word that means "fire."
Igneous rocks form from the
cooling and crystallizing of magma
or lava.

5. Igneous RockIgneous Rock
The size of the mineral crystals in
the rock is affected by the time the
magma or lava cools. The faster it
cools the smaller the minerals are.

6. Igneous RockIgneous Rock
When the rock forms below Earth's
surface it is called intrusive
igneous rock while those formed
on Earth's surface are called
extrusive igneous rocks.

7. Sedimentary RockSedimentary Rock
Sediments like gravel, sand,
silt or clay, are naturally
compacted and cemented
together to form sedimentary
rocks.

8. Sedimentary RockSedimentary Rock
This is the only type of rock
that may contain fossils and
other organic particles.

9. Metamorphic RockMetamorphic Rock
Metamorphic rocks are formed
when an existing rock of any
type is changed by heat or
pressure within Earth.

10. Metamorphic RockMetamorphic Rock
The formation of metamorphic
rocks, called metamorphism,
are caused by the presence of
high heat and pressure but not
enough to melt the rock into
magma.
