Flashcards

Biosphere

The thin layer of Earth that supports life, including the atmosphere, hydrosphere, and lithosphere.

Atmosphere

All the gases surrounding Earth, primarily nitrogen and oxygen. It is divided into four layers: troposphere, stratosphere, mesosphere, and thermosphere.

Troposphere

The layer of the atmosphere closest to Earth, where most weather occurs and where life exists.

Stratosphere

The layer of the atmosphere above the troposphere, containing the ozone layer which protects us from harmful UV radiation.

Greenhouse Effect

Greenhouse gases trap heat from the sun. These gases allow sunlight (solar radiation) to enter the atmosphere, but prevent infrared radiation from escaping back into space, keeping Earth habitable and warmer.

  • Composed of gases
  • Nitrogen (78.08%): Needed for plant growth
  • Oxygen (20.95%): For cellular respiration by organisms
  • Other gases (0.97%): Include water vapor (part of hydrosphere), carbon dioxide, and other gases

Atmospheric Layers

  • Troposphere: Average temperature 15°C; ↑ altitude = ↓ temperature; 80% atmospheric gases; nearly all life here
  • Stratosphere: ↑ altitude = ↑ temperature; contains clumps of cells; contains most of the ozone layer
  • Mesosphere: ↑ altitude = ↓ temperature
  • Thermosphere: ↑ altitude = ↑ temperature; auroras occur here; caused by Earth's magnetic field

Lithosphere/Crust

  • Includes crust and uppermost mantle (rigid outer layer of Earth)
  • 100km deep
  • Contains plants, animals, microorganisms
  • Warmed by Sun's energy and geothermal energy (from the core)

Hydrosphere
