Study Notes
Earth Science Overview
- Earth Science encompasses the study of Earth and its universe, employing observation and experimentation to understand natural phenomena.
- Notable contributions include:
- China: Oldest records of earthquakes and the invention of the first seismoscope (780 BC).
- Ancient Greeks: Early cataloging of rocks and minerals (200 BC).
- Mayans: Advanced tracking of celestial movements, represented in a disk-shaped calendar.
Branches of Earth Science
- Geology: Investigates the origin, history, and structure of solid Earth, including the study of volcanoes by volcanologists.
- Oceanography: Focuses on Earth's oceans, examining waves, tides, and currents.
- Meteorology: Studies Earth's atmosphere, particularly weather and climate, employing tools like Doppler radar for storm tracking.
- Astronomy: The study of the universe beyond Earth, recognized as the oldest branch of Earth science.
Importance of Earth Science
- Understanding natural forces aids in predicting disasters and managing natural resource conservation.
Components of the Universe
- Normal Matter (5%): Composed mainly of hydrogen and helium, includes stars and heavy elements.
- Dark Matter (27%): Essential for galaxy formation, interacts through gravity, remains invisible and undetectable by traditional means.
- Dark Energy (68%): The expansive energy of the universe, propelling galaxies apart; its nature remains largely unknown.
Cosmology
- A subfield of astronomy that explores the universe's origin, large-scale properties, and evolution.
Creation Myths
- Cultural narratives explaining the world’s beginnings include:
- Greek: KHAOS leads to Gaia (Earth), Tartaros (Pit Below), and Eros (Procreation).
- Hindu: Vishnu represents preservation while creating and transforming the universe.
- Egyptian: Atum, the self-created figure, is the origin of all excluding Shu and Tefnut.
