    Study Notes

    The Spheres of Earth

    • The anthrosphere encompasses human-made constructs, including technology, infrastructure, and products.

    Technology

    • Technology is defined as the application of scientific knowledge for practical purposes.

    Biogeochemical Cycles

    • Biogeochemical cycles involve the movement and transformation of elements, such as carbon, nitrogen, and oxygen, through the Earth's systems.
    • These cycles involve the exchange of elements between the atmosphere, hydrosphere, geosphere, and biosphere.

    Factors Influencing Biogeochemical Cycles

    • The strong influence of human activities on the cycles of matter is a significant factor.

    Mineralization

    • Mineralization is the process of converting organic matter into inorganic compounds, releasing nutrients back into the environment.

    Powering Biogeochemical Cycles

    • Biogeochemical cycles are ultimately powered by energy from the sun.

    The Atmosphere

    • The primary role of the atmosphere is to regulate the Earth's climate and provide the air necessary for life.

    Fresh Water

    • Most of Earth's fresh water is found in underground aquifers and ice caps.

    Geosphere

    • The pedosphere, the layer of soil, is directly involved with environmental processes.

    Hydrosphere

    • The hydrosphere is mainly composed of oceans, lakes, and rivers.

    Biosphere

    • The biosphere consists of all living entities on Earth, including microorganisms, plants, and animals.

    Lithosphere

    • The lithosphere is mainly composed of rocks and minerals.

    Carbon in the Biosphere and Anthrosphere

    • The main difference between the occurrence of {CH2O} in the biosphere and anthrosphere is the higher concentration of carbon in the anthrosphere due to human activities.

    Microorganisms in the Carbon Cycle

    • Microorganisms play a crucial role in the carbon cycle by breaking down organic matter and releasing carbon dioxide.

    Microorganism Biodegradation

    • One advantage of microorganism biodegradation is that it can clean up pollutants and contaminants.

    Algae in the Carbon Cycle

    • Algae contribute to the carbon cycle by absorbing carbon dioxide during photosynthesis and releasing oxygen.

    Nitrogen in the Atmosphere

    • Molecular nitrogen (N2) makes up 78% of the elemental nitrogen in the atmosphere.

    Nitrogen Oxides

    • An example of nitrogen oxide present in trace amounts is nitrous oxide (N2O).
