Is the entire ocean floor sand?
The simple answer is that not all of the ocean floor is made of sand. The ocean floor consists of many materials, and it varies by location and depth. In shallow areas along coastlines, you'll mainly find sand on the ocean floor. As you venture deeper, though, you'll encounter other thicker soils and sediments.

Is sand made out of poop?
No, not all sand is fish poop. Sand is made of various bits of natural material and from many different locations. Most of the sand material starts off in-land, from rocks. These large rocks break down from weathering and eroding over thousands and even millions of years, creating smaller rocks.

If you went up into space, above the Earth's atmosphere, the pressure would decrease to zero.
How much lost gold is in the ocean?
