How does physical weathering contribute to creating beach, sandbars and spits

• 
  

  Physical weathering directly erodes coastal areas, creating beaches, sandbars, and spits.

  
  

• Physical weathering releases gases that push sediments towards the coast, forming beaches, sandbars, and spits.

• Physical weathering breaks down rocks into smaller particles that are then transported by wind and water, eventually accumulating in coastal areas.

• Moving away of rocks
