    • Sea level refers to the average height of the ocean's surface around the world.
    • Tides are caused by gravitational forces between the moon, sun, and Earth.
    • Coastal erosion process
      1. Hydraulic action - force of the water crashing against the coastline
      2. Abrasion - rocks thrown at the coastline breaking off rocks
      3. Attrition - rocks crash and break each other up
      4. Air compression - air trapped expands and cracks rock
      5. Solution - acid in water dissolves rock
