• During the Precambrian Eon 4600 - 542 m.y.a.

2) We start to see life on land ONLY AFTER what event happened?

• plate tectonics- plates start to move
• oxygen appears in Earth's atmosphere
• the planet cools and water vapor turns to liquid water

3) Very few fossils are found during the Precambrian Eon because

• most living things were eaten, or had soft bodies that rotted quickly
• plate tectonics destroyed most of the fossil-bearing rocks
• there were very few living things during the Precambrian
• most living things had hard body parts, such as bones or shells

5) Relative Dating is a process used to

• determine the age of a rock in years.
• determine when a particular event happened in history.
• determine the age of a rock compared to the age of other rocks.

6) Absolute Dating is a process used to

• determine the age of a rock in years.
• determine when a particular event happened in history.
• determine the age of a rock compared to the age of other rocks.
