Study Notes
Earth Sciences Overview
- Geology is the primary earth science focusing on Earth's formation and structure.
- Meteorology studies the atmosphere, phenomena within it, and their effects on weather patterns.
- Oceanography investigates the physical, chemical, and biological characteristics of the oceans.
Astronomy and Cosmology
- Astronomy encompasses the study of all celestial bodies and phenomena beyond Earth's atmosphere.
- Cosmology is a subfield of astronomy that explores the universe's origin and evolution.
Key Theories and Concepts
- The Big Bang theory describes the initial event that marked the beginning of the universe.
- The Nebular Hypothesis explains the formation of the solar system, suggesting hydrogen and other gases swirled and condensed into the Sun and its planets.
Celestial Objects
- A meteor is a bright streak of light produced when a meteoroid enters the atmosphere and heats up.
- Asteroids are rocky bodies smaller than planets that orbit the Sun.
- A meteorite is a fragment of a meteor that survives its passage through the atmosphere and lands on Earth.
- Meteoroids are smaller rocky or metallic fragments originating from asteroids, comets, or planets.
- Comets are icy celestial bodies that release gases when they come close to the Sun, creating a visible atmosphere.
