What are the properties of minerals and
rocks?

Types of rocks
1) Sedimentary
rocks
2) Igneous rocks
3) Metamorphic
rocks

Igneous rocks1- Formed when rocks melt and then cool.
1) Rocks are pushed under the earth crust where it melts and turns into magma.
2) Magma comes out of a volcano and cools to form Igneous rocks.When magma comes out of the volcano, it is called LAVA

IfIgneous rocks cool down
quicklyOutside the volcano
(Extrusive igneous rocks)
Look like glassExample:
Basalt
Igneous rocks cools down slowly
Inside the volcano(Intrusive igneous rocks)
Has large grainsExample:Granite

Sedimentary rocks2- Formed when materials settle into layers.
Example:
SandstoneCompressed sand
LimestoneCompressed skeletons and
shells of sea animals

Wind and water break the rocks into small pieces.
Wind and water carries bits of rock and soil away.
Bits of rock and soil settle into layers.
After a long time, layers harden into rocks.
Weathering
Erosion
Sediments
Compression

plants.

Metamorphic rocks3- Formed when other rocks are changed under heat or pressure.
Example:
MarbleTransformed
limestone
SlateTransformed
clay

Pressure from the above layers
Heat from the magma
Any other type of rock
