Warm-ups
6/1 - What eons are in Precambrian time? What were the major events during this long time period?
6/2 - Make a Venn diagram comparing Uniformitarianism with Catastrophism. (DE pgs. 120 to 121)
Make a list of the different kinds of fossils and give an example of each. (DE pgs. 81-83)
6/5 - Work on steps 8 and 9 of the Geologic Time Activity. Start with
The 25 Biggest Turning Points in Earth's History - BBC Earth .
Minor Canyon, AZ
6/6 - 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
6/7 - Make a Venn diagram comparing an Intrusion with a Fault. (DE pgs. 94-96)
6/8 - 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
6/9 - Use the Geologic Timetable to answer the following:
1. What is the first kind of Flora to be found on Earth?
2. What are the era and period each of the following first appear?
Flowering plants, Trilobytes, Mammals, Reptiles
3. When do Trilobytes dissappear?
- 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
- 1) What was the importance of finding Tik-Tal-Lik?
2) How were relative dating principles used?
3) How were absolute dating principles used?
- 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)
- 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?
- Besides worldwide catastrophes, what can cause species to go extinct?
- What are the two big continents formed after Pangaea started to break? What modern continents make up these? (DE pg. 202-203)
- If you were a tree and grew a tree ring during Spring Break, would it be thick or thin?
