    What does "mechanical weathering" mean? How would you define it?

    Right, so what do you know of that breaks down rocks but does NOT change their chemical composition?

    :) No, mechanical weathering is the "process", just as pounding is the process of striking something, but you could say that a hammer is used for pounding.

    So what about the beach? What do you suppose causes the sand, where do you think that sand comes from?

    You could have also said sea shells, as there is a little bit of each of those in the sand. However, the main component of sand is crushed rock.

    What crushes those rocks to make the beach?

    No. A sedimentary rock is just that, a rock. While it is comprised of compressed sediment, it does not produce sand.
