Diagram
Here’s the earth
There’ s a layer around the earth called an ozone layer. The ozone layer protects the earth
Ozone Layer
From all the pollution we have made a hole in the ozone layer Hole
The sun shines in the hole and into the earth
This has increased the average temperature and
caused climate changes to the earths atmosphere and also
causes drought
Farmers:• Australian farmers have been suffering
throughout the drought time .It has been very hard for them to:
• Grow there crops• Grow plants• They have:• Lost a lot of money• There animals have died in the hot

There are 3 types of drought They are
Meteorological drought
Hydrological drought
Agricultural drought
Type of droughts
Meteorological drought
Meteorological drought is generally defined by comparing the rainfall in a particular place and at a particular
time.
The meaning is therefore specific to a particular location
Meteorological drought leads to soil moisture and this always
has an effect on crops production
Hydrological drought
Hydrological Drought is associated with the affect of low rainfalls on water level in reservoirs, rivers & lakes .This type of drought are noticed sometimes after a meteorology drought.
A hydrological drought change in water level affects eco-system
Agricultural drought
Agricultural drought occurs when there isn’t enough water for a crop to grow at
the particular time.
This type of drought doesn’t depend only in the amount of rainfalls where water is used carelessly for irrigation
and other purpose.
