Deposition is like the beach party of geography! It crafts various features like spits and beaches.

Beaches - sandy stages of the sea 🏖️

  • What's needed for a beach party? Lots of materials - like beach deposits, offshore deposits, river sediments, material eroded from cliffs and headlands. They are the party supplies!
  • Longshore drift: Picture this as the conveyor belt, moving these materials along the coast.
  • Beaches are more likely to form on irregular, indented coastlines, like river mouths or low-energy coastlines. It's like the party preferring some corners for all the fun.
  • And don't forget the contribution of plants, or bioconstruction, adding some greenery to the beach.
  • Beaches in the mid and high latitudes usually rock the pebble look, while the tropical ones prefer sandy vibes. It's like different dress codes depending on the location!
  • The form of a beach is impacted by a bunch of factors - material size, shape, composition, tidal range, and wave characteristics. Kinda like how the vibe of a party changes based on music, lighting, crowd and venue.

Beach profiles & sediment size 📏🔍

  • Storm waves in winter can sculpt beaches differently than swell waves in summer. It's like different DJs creating different beats.
  • Steep destructive waves reduce beach angles, whereas gentle constructive waves increase it - the beach dance-off!
  • Different sediments impact the beach profile. Shingle and pebbles allow quick infiltration, reducing the impact of swash (waves washing onto the beach) and backwash (waves washing back to sea). It's like the pebbles laying down a dance floor for the waves!
  • Sand beaches have shallower angles and less percolation. Imagine the sand absorbing the water, slowing down the wave dance-off.
