“the eons, eras and periods used by geologists”
- The period is the basic unit of geological time in which a single type of rock system is formed.
- Two or more periods comprise a geological Era.
- Two or more Eras form an Eon, the largest division of geologic time.

4 factors that affect climate
Latitude affects climate.
Distance from the sea affects climate.
Prevailing winds affect climate.

Coastal areas are cooler and wetter than inland areas. …
In the summer, temperatures can be very hot and dry as moisture from the sea evaporates before it reaches the centre of the land mass.
It will bring cool weather
Warm weather if it blows over warm surfaces
Wet weather if it blows over the sea and picks up moisture
Dry weather if they blow over land
Relief (height). Places which are high up and in mountains have lower temperatures and more rainfall than places which are lower down
