- Predicts Increase in Global Temperatures
- Over past 25 years - +0.2°C per Decade
- Sea Levels Grow (3mm per year)
- Storm Events
- Wave Energy closer to shore and cliff faces
- More coastal erosion
- Places with Soft Rock
The Formation of Beaches
- Constructive Waves
- Strength of Wind and Fetch
- Depositing and Transporting Material
- Geology + Wave Energy
- Long shore Drift
- High and Low Watermark
- Constantly Changing
- Small Particles: Near water
- Big Particles: Further near the Coast
Formation of a Bar
- Spit grows along bay
- Sandbank develops
- Waves and Wind
- Joins to mainland
- Makes a lagoon
- Infilled by Deposition
Thank you for Watching!
The Formation of a Tombolo
What is a Beach, Spit, Bar or Tombolo?
- Created by Long shore Drift
- When Spit continues to grow
- Reaches an Island
- Links to mainland (Bridges)
- DEPOSITION
- Long shore Drift Transports Material
- Formed in Shallow Water
- Salt Marshes can be created
Beaches:
- Land form that lies along the shoreline
- Contain little particles (Sand, gravel, shingle, pebbles and more)
The Formation of a Spit
Spits:
- Extended stretch of beach material
- Out to the sea from the coastline
Bars:
- Ridge of sand and shingle
- Cuts off a bay
- Joins two headlands together
Tombolo:
is a ridge of sand and shingle that joins the mainland to an island.
These are all called:
