Why sands are more prone to quick sand condition than clay?

Sands are more prone to quicksand conditions because they have larger pore spaces between the grains, which allows water to flow more easily through the sediment. When water saturates the sand, it can reduce the friction between the grains and cause them to lose their ability to support weight, creating a quicksand-like effect. Clay particles are much smaller and closer together, which limits the movement of water and makes them less likely to form quicksand conditions.
