Geography Key Words

Atmospheric Air Pressure
the force exerted on the Earth's surface by the weight of the air, which is measured in millibars.
1 of 13
Climate zone
divisions of the Earth's climates into 3 belts zones according to average temperatures and average rainfall
2 of 13
Condensation
the process whereby rising water vapour becomes a liquid
3 of 13
Hemisphere
a half of the Earth, usually divided by the northern and southern halves by the equator
4 of 13
High Pressure
When there is more air pressing down on the ground, caused by sir sinking; air descends and cools
5 of 13
Latitude
the imaginary lines that surround the Earth ranging from 0 degrees at the Equator to 90 degrees at the poles
6 of 13
Low Pressure
caused when the air is rising, so less air in pressing down on the Earth; air rises as it warms

is when the water at the coast of Peru is COLDER than usual and happens half as often.

How Is A Tropical Storm Formed?
They are formed over warm oceans over 27 degrees and 60m deep. The air is warm and rises it then cools allowing the vapour to condense. releasing heat energy and generating a vacuum that sucks more and more warm air into the storm increasing the size
12 of 13
Drought
A drought occurs when theres not enough rain to support people and their needs. Different places have different definitions, in Africa a drought is after 2 years or more of below average rainfall.
