4. Sand is a type of soil best described as: a. mostly decayed matter with tiny rock particles. b. large rock particles and very little decayed matter. c. very small rock particles that hold water well. d. found only on beaches.

The best answer is A, "Mostly decayed matter with tiny rock particles.

Explanation:

Sand is one of the poorest soils, it has very, very low water holding capacity, as well as nutrients. I found the answer because we know it is not B, because sand does not have large rock particles, and we know that it is not c because sand has a very low water holding capacity. And we know that it is not D because it is kinda obvious that sand is not only found on the beach.

Really hope this helps! If I got it right can I have Brainliest?
