    Correct Answer
    B. Skeletons
    Explanation
    Coral reefs are formed by the accumulation of the calcium carbonate skeletons of tiny animals called coral polyps. These polyps secrete a hard exoskeleton that forms the structure of the reef. Over time, as more and more polyps die and their skeletons remain, they build up and create the coral reef. Therefore, the correct answer is "skeletons."

    Which of these BEST describes how sand is formed?

    • A.

      Over thousands of years, ocean waves pound skeletons of reef animals and plants into smaller and smaller bits, which eventually become grains of sand.

    Correct Answer
    A. Over thousands of years, ocean waves pound skeletons of reef animals and plants into smaller and smaller bits, which eventually become grains of sand.
    Explanation
    Sand is formed through a process called weathering, where rocks and minerals are broken down into smaller particles. In the case of sand, the process specifically involves the pounding action of ocean waves on the skeletons of reef animals and plants, gradually breaking them down into smaller and smaller bits. Over thousands of years, these particles become grains of sand. This process is well-documented and understood by scientists.
