Study Notes
Biosphere
- Biological component of Earth, encompassing all living organisms.
- Includes microbes, plants, and animals found from 1 km above sea level to the ocean's deepest depths.
- Represents interconnected ecosystems.
Anthroposphere
- Defined as the "human sphere," it is the section of Earth that has been altered by human activities.
Earth's Composition
-
Crust: The outer rock layer, only about 1% of Earth's volume, includes:
- Continental Crust: 30-70 km thick.
- Oceanic Crust: 5-7 km thick.
-
Mantle: Makes up 82% of Earth's volume, consisting of:
- Upper Mantle: Cooler, solid magma.
- Lower Mantle: Weaker, semi-solid magma.
-
Core: Composed of iron and nickel:
- Outer Core: 2,260 km thick, liquid state.
- Inner Core: Solid form.
Atmosphere
- Five layers:
- Troposphere: Contains over half of the atmosphere's air; temperature decreases with height; hosts most weather and pollution.
- Stratosphere: Contains protective ozone layer; volcanic gases can persist here.
- Mesosphere: Temperature decreases with height.
- Thermosphere: Temperature rises rapidly; influenced by solar radiation.
- Exosphere: Outermost layer; light gases escape into space.
- Atmospheric Composition:
- Nitrogen (N2): 78%
- Oxygen (O2): 21%
- Argon (Ar): 0.9%
- Carbon Dioxide: 0.03%
- Water Vapor: 0-4%
Cryosphere
- Derived from Greek "krios" meaning cold; includes regions with solid frozen water.
- Snow and ice are crucial in regulating Earth's climate by reflecting solar heat.
Water Cycle
- Involves processes such as:
- Cloud formation and water vapor.
- Precipitation and surface runoff.
- Freshwater storage in ice, snow, and groundwater.
- Water evaporation and transpiration.
Earth System
- A closed system regarding matter; only energy is exchanged with the sun and space.
Hydrosphere
- Encompasses all water bodies on Earth, constituting around 70% of the planet's surface.
- Groundwater represents the largest freshwater reservoir.
Main Spheres of Earth System
- Includes atmosphere, hydrosphere, geosphere, and biosphere.
Concept Highlights
- Ecosystem interactions and components influence the overall health of the planet.
- Various spheres work together to maintain balance in Earth's systems.
