    Study Notes

    Introduction to Earth Science

    • Earth Science is composed of four branches: Geology, Oceanography, Meteorology, and Astronomy.

    Geology

    • Deals with the composition of Earth materials, Earth structures, and Earth processes.
    • Physical Geology examines the material composing Earth and seeks to understand the many processes that operate beneath and upon its surface.
    • Historical Geology is concerned with understanding the origin of Earth and the development of the planet through its 4.6 billion-year history.

    Oceanography

    • Involves the application of all sciences in a comprehensive and interrelated study of the oceans in all their aspects and relationships.
    • Integrates chemistry, physics, geology, and biology.
    • Includes the study of the composition and movements of seawater, as well as coastal processes, seafloor topography, and marine life.

    Meteorology

    • Is the study of the atmosphere and the processes that produce weather and climate.
    • Involves the application of other sciences in an integrated study of the atmosphere and processes that produce weather and climate.

    Astronomy

    • Is the study of the universe and the heavenly bodies.

    Scientific Method

    • Involves research, analysis, and presentation of findings related to Earth science topics.

    Rocks

    • Minerals are composed of elements, which are the building blocks of minerals.
    • Elements can be stable or unstable, and most minerals are a combination of two or more elements.
    • Atomic number is important in understanding the composition of minerals.
    • Atoms bond through ionic and covalent bonds, forming ions, anions, and cations.
    • Example: NaCl (sodium chloride) is formed through ionic bonding.
    • Difference between a rock and a mineral: When elements join to form a mineral, the constituent elements lose their physical properties.
