    Study Notes

    Spheres of the Earth

    • The biosphere is the only biotic sphere of the Earth.
    • The Greek prefix 'geo-' means earth or ground.

    Geosphere

    • The geosphere is composed of solid land in Earth's crust.
    • The inner core of the geosphere has a temperature of around 5,000°C to 6,000°C (9,000°F to 11,000°F).
    • The hottest layer of the geosphere is the core.
    • The layer of the geosphere composed of liquid iron and nickel is the outer core.
    • The geosphere is made up of the crust, mantle, outer core, and inner core.
    • Human activities such as deforestation negatively affect the geosphere.

    Atmosphere

    • The word 'atmosphere' originates from the Greek words 'atmos' meaning vapor and 'sphaira' meaning sphere.
    • The most abundant gas in the Earth's atmosphere is nitrogen.
    • Oxygen makes up around 21% of the atmosphere.
    • The stratosphere is responsible for blocking ultraviolet radiation.
    • The troposphere accounts for nearly 15 kilometers above Earth's surface.
    • Water vapor in the atmosphere connects the hydrosphere and atmosphere.
    • The atmosphere is responsible for humidity on a muggy day.

    Hydrosphere

    • The majority of the water on Earth (around 97%) is present in oceans.
    • Water exists mainly in the liquid form in the hydrosphere.
    • The hydrosphere is connected to the atmosphere through water vapor.

    Biosphere

    • The biosphere is the sphere of the Earth where most organisms live, including oceans, land, and atmosphere.
    • Rainfall connects the hydrosphere and biosphere.
    • Some organisms can be found in the atmosphere, ice, and water within the biosphere.
    • The biosphere is distinguished from the other three spheres in that it is the only one that supports life.
    • The lithosphere is primarily abiotic in nature.

    Interconnections

    • Water vapor in the atmosphere connects the hydrosphere and atmosphere.
    • Rainfall connects the hydrosphere and biosphere.
    • The biosphere is affected when humans cut down trees for industrialization.
