We use minerals like diamonds to make jewellery.
Rocks are materials made up of minerals.
We dig mines to obtain rocks that are under the ground.
We dig quarries to obtain rocks that are on the surface.
ROCKS ARE USEFUL
Slate,marble and granite are used for building.
Coal is used for fuel.We burn it to obtain heat.
Granite is hard and resistant.
TYPES OF SOIL
The ground is made up of rocks,sand,soil,air,water and
Humus is the remains of living things like leaves.
Fertile ground has a lot of water,air and humus.
It is good for plants.
Poor ground has little water, air and humus.
Only resistant plants, like olive trees, can grow in
VERY POOR GROUND
Very poor ground, for example in the desert, very few
plants can grow there.
Some water from rain filters through the ground,
and reaches the bottom layer of rocks.
These rocks do not let the water filter any further.
It stops and becomes underground water.
In deserts, this underground water creates an oasis.
An oasis is where people and animals can find water.
