    Study Notes

    Earth’s Subsystems

    • Biosphere: Comprises all living organisms and ecosystems on Earth.
    • Hydrosphere: Encompasses all water bodies, including oceans, glaciers, rivers, and groundwater.
    • Geosphere: Represents the solid portions of the Earth, extending from the core to the crust, including:
      • Crust
      • Mantle
      • Outer core
      • Inner core
    • Atmosphere: Layer of gases surrounding the planet, primarily made of:
      • Nitrogen (78%)
      • Oxygen (21%)
      • Other gases (1%), including argon, carbon dioxide, carbon monoxide, and ozone.

    Interactions Among Subsystems

    • Atmosphere provides heat and energy to the geosphere, facilitating rock breakdown and erosion processes.
    • Biosphere receives essential elements such as gases, heat, and sunlight (energy) from the atmosphere, as well as water from the hydrosphere and a supportive environment from the geosphere.

    Essential Elements

    • Temperature: Regulated primarily by solar energy from the Sun, influencing atmospheric conditions.
    • Water: Critical for all life forms and processes; part of the hydrosphere.
    • Energy: Vital for driving biological and geological processes; derived from the Sun.

    Minerals

    • Defined as the building blocks of rocks.
    • Characteristics of minerals:
      • Naturally Occurring: Formed through Earth's natural geological processes.
      • Inorganic: Not produced by biological processes; must originate from physical processes of the Earth.
      • Homogeneous Solid: Possess a definite and uniform shape and volume.
      • Crystalline Structure: Atoms are arranged in an orderly repeating pattern.
      • Chemical Composition: Can be represented by a specific chemical formula.
