Tropical Forests
1. Located near the equator between the Tropic of Capricorn and the Tropic of Cancer2. Characterised by very hot temperatures and high average annual rainfall (over than 1500mm pa) without distinct dry season
Savanna
1. Located in large surfaces in Africa, Australia, South America2. Characterised by hot, wet summers and warm, dry winters (rainfall 500-1000mm pa)
Desert Biomes
They are the Hot and Dry Deserts, Semi Arid Deserts, Coastal Deserts and Cold Deserts1. Located around tropics for hot deserts, high latitudes for cold deserts2. Characterised by little rainfall (less than 250mm pa), large temperature ranges during the day, high evaporation rates, drought resistant vegetation
Chaparral
1. Located around the Mediterranean Sea and other coastal regions2. Characterised by hot and dry summers, mild and moist winters (roughly 400mm rainfall) and constant fires (adapted by short hard shrub vegetation)
Temperate Grasslands
1. Located in North America and Eastern Europe2. Characterised by cold winters and warm summers with some rain (250-900mm pa), dense vegetation bc of high soil fertility, frequent fires
Temperate Forests
1. Located around mid-latitude regions2. Characterised by high range of temperatures (below freezing to average temperature 20-20c), consistent precipitation (750-1500mm) and found between tropical and boreal regions
Boreal Forests
1. Located in the latitude range of 50-60 degrees North2. Characterised with cold and dry winters and short, cool and wet summers (precipitation 400-1000mm) and high dominance of cold tolerant vegetation
Tundra Biomes
1. Located in very cold regions of the Northern Hemisphere2. Characterised by extremely low temperatures, little precipitation (150-250mm), short growing seasons, low vegetation, winter temperature (-34c) and summer temperature (12c)
Isobars
Isobars (measured in hPa: hectopascal) connect areas of equal air pressure with higher air pressure with closer isobars together and lower air pressure with further apart isobars
Wind Sticks
Wind sticks show the direction of where the wind is coming from and the tail shows the wind speed and it tells geographers whether a place is likely to experience warmer or colder temperatures
High Pressure Cells
High pressure cells are areas of descending air with highest air pressure value in the centre of the cell also known as anti-cyclones- rotates anticlockwise in Northern Hemisphere- generally fine weather, calm conditions and gentle breeze
Low Pressure Cells
Low pressure cells are areas of ascending air with lowest air pressure value int he centre of the cell also known as cyclones- rotates clockwise in Northern Hemisphere- cloudy, unsettled weather and chances of rain
Cold Front
Cold Front is when two opposing air masses meet driven by cold air mass meeting a warm air mass- change in wind direction- decrease in temperature- cloudy conditions- chance of rain
