Tectonic forces
driven by the heat (and therefore movement) radiating from the Earth’s liquid mantle/core.
Example of tectonic forces
folding moutnains, volcanoes, earthquakes
Gradational forces
external forces which are driven by Earth’s gravity and heat energy from the Sun. These modify the lithosphere by smoothing it.
Examples of gradational forces
Weathering, erosion, mass movement, deposition
global patterns of climate
variations in isolation, earths rotation and revoltion on the axis, composition of atmopshere, distrubution of ocean currents, topography
examples for each pattern of climate
distance from sun (equator compared to poles) and global heat budget, seasons changing each year, greenhouse effect and enhanced, warm currents higher evaporation rate and proximity to oceans, rainshadow and orographic rainfall
Evaporation
the sun shines on water and heats it, turning it into gas called water vapour which rises into the atmosphere.
Precipitation
when water droplets fall from the sky as rain, snow or hail.
Condensation
water vapour in the air cools and turns back into a liquid, forming tiny water droplets in the sky.
Accumulation
the process of water collecting in rivers, lakes, streams, oceans and other bodies of water.
Transpiration
the sun warms people, plants and animals and they release water vapour into the atmosphere.
Surface Run off
when water flows over the ground and into creeks, rivers and oceans.
Infiltration
when water falls on the ground and soaks into the soil.
percolation
when water seeps deeper into tiny spaces in the soil and rock.
Orographic rainfall
produced when moist air is lifted as it moves over a mountain range. As the air rises and cools, orographic clouds form and serve as the source of the precipitation. lots of biodiversity and diversity
Most of the rain will fall on the windward side of the mountain ridge. On the leeward mountain range side rainfall is usually low and the area is said to be in a rain shadow. arid and dry, not much vegetation
Factors of vegetation
climate, topographic, edaphic, biotic
Climate vegetation factor
certain moisture and temperature condition to grow (precipitation, light, temperature, wind)
Topographic vegetation factors
Effected indirectly by altitude, aspect, and degree of slope (
Edaphic vegetation factors
Mature soils vary in different biomes
Biotic vegetation factors
relationship between plants and animals in ecosystem (symbiotic relationships, human impacts on environments)
