Question1
A sediment core is retrieved from the middle of the North Pacific Ocean, about 1000 kilometers (620 miles)
south of the Aleutian Islands (1/4 the way to Hawaii), and at a water depth of 5000 meters (16,400 feet). The
core contains coral reef fossils, which are only found in shallow, tropical waters.
• A) Develop a hypothesis that could explain this occurrence.
B) Develop a test for your hypothesis
.
Question 2
A) Discuss how a deposit with a coarse grain size indicates whether it was deposited by a high- or low-energy
transporting mechanism.
B) Give at least 2 examples of various transporting mechanisms that would produce such a deposit.
