1. ROCKS
There are 3 different types of rocks called Metamorphic, Igneous and Sedimentary
rocks.

2. The rock cycle
●

3. Igneous rocks
● Igneous rock is formed when magma cools and solidifies, it may do this above or
below the Earth's surface. Examples of Igneous

4. Sedimentary rocks
Sedimentary rocks are types of rock that
are formed by the deposition of material
at the Earth's surface and within bodies
of water.
For example
Sandstone
Limestone
Shale

5. Metamorphic
Marble
Slate
Metamorphic rocks are formed
when rocks are close to some
molten magma, and so get heated
up.

● Igneous rock is formed when magma cools and solidifies, it may do this above or below the Earth's
surface. Igneous rocks are divided into two different groups called the intrusive and extrusive rocks.
Intrusive are volcanic rocks and extrusive are plutonic rocks. Plutonic rocks are formed under ground
and volcanic are formed on land. Basalt forms the metamorphic rock granulite when subjected to
extreme heat and pressure over time. Most extrusive rocks have got crystals.
Sedimentary rocks are types of rock that are formed by the deposition of material at the
Earth's surface and within bodies of water. Shale rocks can be made out of different layers
compressed together.
● Metamorphic rocks are formed when rocks are close to some molten magma, and so get heated up.
The minerals they contain are changed chemically, forming metamorphic rocks.Basalt forms the
metamorphic rock granulite when subjected to extreme heat and pressure over timeThe original rock
is subjected to heat temperatures greater than 150 to 200 °C and pressure 1500 bars, causing
difficult physical and chemical change. Metamorphic minerals are those that form only at the high
temperatures and pressures associated with the process of metamorphism. These minerals, known
as index minerals, examples sillimanite, kyanite, and some garnet.
