Question

stones and pebbles from sand

Answer 1

Answer:

Hey mate I can't understand the question but I think it is your answer.

Explanation:

Stones and rocks and boulders and pebbles are all the same things: rock material. The main difference is size. Stone is generally used for large amounts, rock is just the generic term, boulders are pieces of rock bigger than a foot across or so, and pebbles are smaller than 2.5 inches - roughly.
