Study Notes
Hydrosphere
- Comprises a dynamic mass of water, continually cycle through evaporation, precipitation, and runoff.
- Water evaporates from oceans, precipitates onto land, and returns to oceans, creating a constant movement.
Atmosphere
- Gaseous envelope surrounding Earth essential for supporting life.
- Facilitates energy exchanges leading to weather and climate phenomena.
- Climate changes significantly impact Earth’s surface processes, influencing their intensity and nature.
Impact of No Atmosphere
- Without an atmosphere, Earth would resemble the Moon: lifeless and unchanged.
- Key processes such as weathering and erosion would cease, impacting the planet’s surface dynamics.
Biosphere
- Encompasses all life on Earth, with ocean life primarily found in sunlit surface waters.
- Terrestrial life is largely concentrated near the surface, involving tree roots, burrowing animals, and aerial creatures like insects and birds.
- Life forms exist in extreme environments, showcasing biodiversity.
Geosphere
- The solid Earth beneath the atmosphere and ocean extends to a depth of 6,400 kilometers (4,000 miles).
- Largest of Earth’s spheres, containing soil as a critical layer that supports plant growth.
- Soil is a mix of weathered rock debris (geosphere) and organic matter from decaying plants and animals (biosphere).
