Word of the Week: Evident - obvious Science Word of the Day: Law of Superposition - in horizontal sedimentary rock layers the oldest layer is at the bottom.

II. EQ: What can you infer about Earth's age from rock layers and index fossils?

Friday, 27 September 2019 - Relative Age of Rocks

CO: (8.E.2.1) You will infer the age of Earth and relative age of rocks and fossils from index fossils and ordering of rock layers (relative dating (age) and radioactive dating)LO: You can participate in reading and discussion of the relative age of rocks.EQ: What can you infer about Earth's age from rock layers and index fossils?

Warm-Up Activity - On previous page.

Classwork

1. Watch video describing Relative Dating, and take notes to answer guided questions2. Class discussion / review of the Law of Superposition

As you watch, try to answer the following

questions:

1. What does the position of rock layers

reveal?

2. How do geologists determine the relative

age of a rock?

3. How are fossils used to date rocks?
