Study Notes
Earth Science Module 14: The History of Earth Through Geologic Time
- This module details the history of Earth, from its creation to the present day, through geological time.
- Earth's history spans billions of years, much longer than human history.
- Geological and paleontological methods are used to understand Earth's age and the history of life on Earth.
- The geologic time scale divides Earth's history into eons, eras, periods, epochs, and ages. This scale is based on major events in Earth's history.
- Precambrian:
- The longest span of the geologic time (88% or 4.1 billion years).
- Three parts: Hadean Eon (Earth's formation, severe volcanic activity, and meteor impacts), Archean Eon (early life, formation of continents, and oceans, atmospheric changes), and Proterozoic Eon (rise of oxygen, formation of multicellular organisms).
- Phanerozoic Eon:
- Divided into the Paleozoic Era ("ancient life"), Mesozoic Era ("middle life"), and Cenozoic Era ("recent life").
- Paleozoic Era features the development of marine invertebrates, first land plants, and early vertebrates.
- Mesozoic Era sees the dominance of reptiles and dinosaurs, and the emergence of early mammals.
- Cenozoic Era marks the rise of mammals, including humans.
- Evidence of fossils and other geological features help divide these into further units.
- Divided into the Paleozoic Era ("ancient life"), Mesozoic Era ("middle life"), and Cenozoic Era ("recent life").
- Geologic time scale helps track Earth's history and major events across long spans of time.
- The module explains how absolute and relative dating are used to determine eras' subdivisions.
- Various activities like timelines and other exercises aid in learning the history of Earth.
