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.
