Why are sand-sized particles easier to erode than clay-sized particles?
A)because sand grains are rounder and roll more easily,whereas clay particles are flat and platy
B)because sand grains are typically made of quartz,which saltates more easily than clay particles
C)because clay particles are denser than sand particles,making them heavier
D)because clay particles are attracted to tone another because of opposite charges,which hold them in place

Question

Quizplus · Accepted Answer

Clay particles have opposite charges on their surfaces, which leads to electrostatic attraction between them. This attraction causes the particles to clump together, making them more resistant to erosion compared to sand-sized particles that do not have such strong inter-particle attractions.
