Sand Beaches vs. Shingle Beaches: Key Differences

Sand Beaches

• Composed of small, loose particles (quartz, feldspar, mica).
• Formed by wave erosion of cliffs/headlands and river transport.
• Colors vary by mineral content: white (quartz), pink (feldspar), black (mica).
• Well-sorted (uniform particle size).
• Minimal organic material.

Shingle Beaches

• Made of larger, rounded rock particles ("shingle").
• Also formed by wave erosion and river transport.
• Typically grey, brown, or black.
• Poorly sorted (mixed particle sizes).
• Contain significant organic material (shells, seaweed).

In summary, the two beach types differ in particle size, composition, sorting, and organic content.
