Why is there sand on the ocean floor?

Answer 1

Basically, because sand is heavier than water and sinks.

Sand is constantly being created by erosion - both by water and wind - of solid rock. It gets carried by turbulent water but it eventually settles to the bottom of all watercourses - rivers, lakes and seas.

Answer 2

Sand is created on seashores by the action of waves against rocks, which breaks rocks down into sand. Sand moves around over time, and so ocean areas close to shore usually are very sandy as well. Deep ocean floors are often covered with mud or silt rather than sand.

Answer 3

Rocks rubbing against each other wearing down and breaking tiny bits off which are worn down and all the endy worn down bits are sand, and all the tiny bits that were worn off are sand.

Answer 4

To take a lot of hard waves
