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.
