Types of erosion

• Solution: Dissolving of soluble chemicals in rock (e.g: limestone)
• Corrosion: Rock fragments picked up by sea and thrown at the cliff, they scrape and wear away the rock
• Abrasion: 'sandpapering' effect of pebbles grinding over a rocky platform
• Attrition: Rock fragments carried by sea knock against each other becoming smaller or more round
• Hydraulic action: Power of waves as they hit a cliff, trapped air is forced into cracks eventually causing the rock to break up
