Document Summary
Atmosphere - a spherical mass of air surrounding the earth"s surface. Troposphere - the innermost layer of the atmosphere. Stratosphere - next layer in the atmosphere; reaches 17-50 km above the earth"s surface. The layer of the stratosphere that"s closest to the earth"s surface contains enough ozone to filter out 95% of the sun"s harmful rays. Hydrosphere - includes all the water on or near the earth"s surface. Liquid water in on the surface and underground. Geosphere - contains the earth"s rocks, minerals, and soil. Thin outer crust of rock and soil. Biosphere - consists of the parts of the atmosphere, hydrosphere, and geosphere where life is found. Greenhouse effect - when solar energy interacts with carbon dioxide and other gases, it warms the troposphere. Nutrient cycling - recycling of nutrients from organisms. Trophic level - feeding level in an ecosystem. Producers / autotrophs - create their own nutrients from compounds gained through the environment.
