ROCKS
Origin
Sedimentary
Formed from fragments of other rocks
Metamorphic
Formed by pressure and heat
Igneus
Lava or magma solidifies
Texture
Depend on the form , size and crystal grains
Composition
One mineral
Several minerals
Types of rocks
Plutonic rock
They have got crystals
Formed by solidified magma
Granite
Most abundant in land
Most used in construction
Periodite
Most abundant rock in mantle
Metamorphic rock
For example
Slate
Has got very tiny crystals
Scritch
Crystals can be seen easily
Geneiss
This is formed of larger crystals
Some of them have got layered
They have been tranformed
Sedimentary rocks
Types
Sandstones
Clays
Conglomerate
Sedimentary rocks with grains
Thinner material matrix
Formed the composition of
Sediments
Fragments of other rocks
