Earth's History 3/28 to 4/25

Warm-ups

3/28 If you were a tree and grew a tree ring during Spring Break, would it be thick or thin?

3/29 Make a Venn diagram comparing Uniformitarianism with Catastrophism. (DE pgs. 120 to 121)

3/30 Make a list of the different kinds of fossils and give an example of each. (DE pgs. 81-83)

3/31 Use the principle of superposition to list the youngest 3 strata of Minor Canyon from youngest to oldest. Animation of Minor Canyon Formation – mheducation.com

4/4 Make a Venn diagram comparing an Intrusion with a Fault. (DE pgs. 94-96)

4/5 List the strata from minor canyon from youngest to oldest. (Hint: Start from the bottom and use the principles of superposition and crosscutting to determine what is younger) Animation of Minor Canyon Formation – mheducation.com

4/6 List the events and strata in order from youngest to oldest. Write "tilting", "folding" and "erosion" when those events take place. Earth Science Lab: Relative Dating - facweb.bhc.edu

4/11 1) What was the importance of finding Tik-Tal-Lik?

2) How were relative dating principles used?

3) How were absolute dating principles used?

4/13 What kinds of rock are we to find in the 3 and 4 billion Continental Shield rock? (DE pgs. 124-127, Old ES pg. 152)

4/14 A fossil of a mosquito in amber has 0.5 (one-half or 50%) of the original carbon-14 material in it. If the half-life of carbon-14 is 5730 years, how old is the mosquito?

4/18 Besides worldwide catastrophes, what can cause species to go extinct?

4/20 What are the two big continents formed after Pangaea started to break? What modern continents make up these? (DE pg. 202-203)

Objectives

• Explain how Earth materials, such as rock, fossils, and ice, show that Earth has changed over time.

• Summarize how scientists measure the relative ages of rock layers.

• Identify gaps in the rock record.

  • Describe how geologists use a geologic time scale to divide Earth's history.
