describe what the atmosphere includes:
the air around us
what is the biosphere
anything organic
what is the hydrosphere
anything that is water
what is the cryosphere
water frozen in snow, ice, and glaciers
what is the lithosphere
the earths outermost layer
What is the primary factor that influences climate at a given location
latitude
where is the greatest amount of solar radiation received on earths surface

the axis, orbit, timing of seasons and earths distance from the sun
how do humans impact climate
human activities
what is deforestation
clearing a large area of a forest
how does deforestation impact climate change
all the Co2 in the cut down trees are released
what are two ways the carbon cycle is affected
less Co2 intake by plants, and decaying plants give of Co2
