What is Quicksand?

Quicksand is a bed of loose sand mixed with water. It is found in places such as river banks and sea coast where there is a layer of impervious clay below. Although it looks like solid ground, quicksand cannot support weight and any person stepping on it may sink and get trapped. This happens because the water seeping in from the nearby water body remains trapped in the quicksand because of the impervious bottom underneath.
