REVIEW OF GEOGRAPHY TERMS.
Atmosphere Gases Surrounding the earth
Biosphere Living and non-living organic matter
Hydrosphere Water components
Lithosphere Rocks, minerals and soil
Non-living components Anything that is not alive or have ever been alive.
Living components Anything (a person, animal or plant) that has ever been alive
Living things Anything that is alive
Climate The weather conditions prevailing in an area in general or over a long period.
Topography the arrangement of the natural and artificial physical features of an area
Natural vegetation Plants that have not been grown by humans
Soils The upper layer of earth in which plants grow, consisting of a mixture of organic remains, clay, and rock particles.
Natural system Something that exists in nature, independent of human involvement
Inputs Items or forces that enter the system, such as wind or precipitation
Components The material things that make up a natural system, for example vegetation, rocks, water, air.
Processes The methods of operation or types of actions within the system by which energy or matter are moved into, around or out of the system for example, weathering, erosion, transportation, deposition, evaporation, photosynthesis.
Outputs Matter or energy leaving the natural system, such as sediments carried by a river, or water vapour ascending into the atmosphere above the ocean.
Geography Focuses on the distribution of natural phenomena and the interaction of humans with the natural world.
The four spheres Atmosphere, Biosphere, Hydrosphere, Lithosphere
Weathering Physical, chemical or biological breakdown of rocks and minerals into smaller sized particles.
Erosion The removal of weathered sediment or rocks by the forces of wind, water, and ice.
Transportation The movement of eroded material in the medium of air, water or ice.
Deposition Laying down of sediment transported by wind, water, or ice.
Evaporation The process by which liquid water is converted into a gaseous state
photosynthesis Is the chemical process where plants and some bacteria can capture and organically fix the energy of the Sun.
Ecosystem A system formed by the interaction of a community or organisms with their physical environment
Biome Largest recognizable assemblage of animals and plants on the Earth. The distribution is controlled mainly by climate.
symbiosis Mutual relationship between two organisms which is necessary for either to survive.
