Sand and gravel have different angles of repose.

Question

Quizplus · Accepted Answer

Sand and gravel have different particle sizes and shapes, which can result in different angles of repose. Sand typically has a lower angle of repose than gravel as it has smaller and rounder particles that can settle closer together, creating a more stable slope. Gravel, on the other hand, may have a higher angle of repose due to its larger and angular particles, making it more prone to sliding and movement.
