A sediment core is retrieved from the middle of the North Pacific Ocean, about 1000 kilometers (620 miles) south of the Aleutian Islands (Alaska), 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. Develop a hypothesis that could explain this occurrence. Also, develop a test for your hypothesis

You are a researcher for a golf club manufacturer. you are given two identical looking cubes of a metal alloy. you are informed that they are made of the exact same material, but one is crystalline, whereas the other is amorphous. it is your job to determine which one is amorphous this one is more stress-resistant and is useful in reinforcing golf clubs. which of the following is the best way to determine which is which? a. determine the density of each cube. the more dense one is the amorphous solid. b. melt both cubes and look for a broader range of melting temperatures. the one that melts over a broader range of temperatures is the amorphous solid. c. determine the density of each cube. the less dense cube is the amorphous solid. d. melt both cubes and measure the range of melting temperatures. the one that melts over a narrower range of temperatures is the amorphous solid.
