Question 1
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.
