Textbook Connection:
- Geologic TIme Scale- Chapter 18 section 1 and section 2
- Fossils- Chapter 17 section 3
Essential Questions:
- What major events occurred over the Earth's 4.6 billion years history?
- How is geologic time divided so that 4.6 billion years are comprehensible?
- Where do humans fit into the geologic time scale?
Enduring Understandings:
- Geologic time is divided into Eons, which are divided into Eras, which are divided into Periods.
- The Precambrian Supereon makes up an astounding 7/8ths of Earth's history.
- The Phanerozoic Eon (Paleozoic, Mesozoic, and Cenozoic Eras) make up the remainder of Earth's history.
- The Paleozoic ("Ancient Life") Era is known as the Age of Fish.
- The Mesozoic ("Middle Life") Era is known as the Age of Reptiles.
- The Cenzoic ("Most Recent") Era is known as the Age of Mammals.
- Life is adapted to varying conditions on Earth.
- The solid crust of the earth consists of separate plates that ride on a denser, hot, gradually defomable layer of earth.
- The ocean and continental crusts move slowly.
- The force of gravity enables the planet to retain an atmosphere.
