Everything in or on water pushes some water aside even if it's just a little bit What is this called
This is called "displacement", as the weight of water that moves is equal to the weight of the object on the water. Heavier objects displace more water. If the total weight of the object is greater than the water displaced by its volume, it is denser than water, and sinks.
