Study Notes
Earth System Interactions & Cycles
- The Earth System is comprised of four interconnected systems:
- Atmosphere: The thin layer of gases and particles surrounding Earth.
- Hydrosphere: All of Earth's water, mostly on the surface.
- Geosphere: The solid Earth, including the thin layer of soil and rocks on the surface and internal layers.
- Biosphere: All living things on Earth, interacting within all other systems.
Layers of the Atmosphere
- Troposphere: The layer closest to Earth's surface (8-15 km), where temperature decreases with altitude.
- Stratosphere: Directly above the troposphere (15-50 km), containing the Ozone Layer which protects Earth from the Sun's ultraviolet rays.
- Mesosphere: Directly above the stratosphere (50-85 km), protects Earth from meteors.
- Thermosphere: Directly above the mesosphere (85-500 km), the highest temperature layer, containing most satellites.
- Exosphere: The farthest layer from Earth's surface, with no definite edge, where molecules escape gravity due to high speed.
- Ionosphere: Between the mesosphere and thermosphere (60-500 km), containing ions that reflect AM radio waves.
Processes within Earth's Systems
- Water Cycle: Continuous movement of water on, above, and below Earth's surface.
- Evaporation: Liquid water changing to vapor.
- Condensation: Water vapor changing to liquid.
- Transpiration: Water vapor released from plants and soil.
- Rock Cycle: Series of processes changing rocks from one form to another.
- Weathering: Breakdown of rocks and minerals on Earth's surface.
- Erosion: Transporting broken-down rock and mineral fragments.
- Carbon Cycle: Continuously moves carbon among Earth's systems.
- Photosynthesis: Removes carbon dioxide from the atmosphere.
- Cellular respiration: Returns carbon dioxide to the atmosphere.
- Phosphorus Cycle: Moves phosphorus among Earth's systems.
- Phosphorus is a key element for all organisms, present in rocks, water, and organisms.
- Human activities, like deforestation, can disrupt the cycle.
Key Facts
- The Earth's atmosphere makes up a small fraction of the planet's total mass.
- The majority of Earth's water is saltwater, found in oceans.
- The geosphere is the largest Earth system, including internal layers and surface rocks.
- The biosphere relies on all other Earth systems for resources and survival.
