Document Summary
Hydrosphere: solid, liquid, and gaseous water. Lithosphere: crust and upper mantle, contains non-renewable resources. One-way flow of high quality of energy. Cycling of matter (the earth is a closed system) Gravity: causes downward movement of matter, process of renewal. Abiotic components: water, air, temperature, soil, light levels, precipitation, salinity, sets tolerance limits for populations and communities, some are limiting factors that structure the abundance of populations. Biotic components: producers, consumers, decomposers, plants, animals, bacteria/fungi, biotic interactions with biotic components include predation, competition, symbiosis, parasitism, commensalism. Limiting factors on land and in h20: terrestrial. Three ways energy is transferred: convection, conduction, and radiation. Varies with wavelength/frequency producing different properties of energy the em spectrum. All objects having a temperature above absolute zero emit em radiation. 99% of the solar radiation emitted has a wavelength between 0. 15 and. Changes from radiant energy to thermal energy and kinetic energy.
