the current world biomes.
short growing season of 3 month or less
cool temperature, average about 10"c
vegetation contains more grasses and sedge than alpine tundra.
Boreal coniferous forest.
occurs in Eurasia, Alaska ,Canada
not rich in diversity.
northern coniferous forest
tropical grassland and savanna
best known savanna in Africa, Brazil
abundant colonies and mounds so large that termites nutrient cycling.
rains occurs almost everyday.
large tress go massive pollination.
Shrublands and woodlands
shrublans are similar except replaced by shrubs.
low rainfall causes the drier environment and causes fire
woodlands is similar to forest except it don't form canopy
either cold or hot based on winter temperature.
plants on desert are Bursage, Agaves prickly pear.
driest region of temperate regions, rainfall less than 25cm/yr.
central plain of north America are grasslands.
referred as prairie
are eligible for farming.
located above the highest point at which tree survive on mountain.
cold much of year
short growing season limited
late snow melt and early fall in autumn.
drier montane and subalpine forests
mixed coniferous forest
cold winter and warm to cool summers.
drier and shed less rain
temperate rain forest
dominated by giant long lived conifers
often called lungs of planet
temperate deciduous forest
occupies lower and warmer regions.
forest is not uniform across the breadth
cold winters and warm but not hot summer
southeastern evergreen forests
region has dry aspects to it
more fire catching forest and repeatdly supressing.
shows the powerful effect that disturbance and soil type exert.
Atmospheric distribution of heat
greenhouse effect causes the heat
conduction, convention and turbulence.
heat from core of earth, radiation and conduction.
Oceanic distribution of heat
then to the poles and cold water from the poles back to the tropics.
store solar radiation and distribute around globe.
act as a conveyor belt, transporting warm water and precipitation from the equator
effects of earth tilt
more tilt is more severe seasons
less tilt is less severe seasons
tilted towards sun receives more radiation and viceversa
past position of world's continent
middle and late paleozoic era
life begin to move on land
colison between Eurasia and north America formed Appalachian mountains.
evolution of plants occured
continent5s started to seprated.
temperature got warmed
life was aquatic
eurasia and gondwanland
present position of world's continent
only planet having liquid in surface
important factors to determine climate through latitude
near equator is warm and humid and other is cooler.
has seven continents
