Lesson details

Key learning points

  1. Happisburgh is experiencing some of the fastest coastal erosion rates in the UK.
  2. Physical processes make the Happisburgh coastline vulnerable to erosion.
  3. Human processes play a significant role in the rate of coastal erosion at Happisburgh.

Keywords

  • Erosion - the wearing away of rocks along the coastline

  • Climate change - long-term shifts in temperatures and weather patterns

  • Coastal management - the protection of coastlines from erosion and flooding through artificial or natural methods

Common misconception

Coastal management always positively impacts coastlines.

Coastal management can sometimes harm coastlines by causing erosion in nearby areas. For example, building groynes may protect one section but increase erosion further down the coast.

GIS can be used in this lesson to investigate the coastal erosion of area by comparing historic and modern maps.

Q6.
Select the answers that correctly describe impacts of climate change on coastlines.
Correct answer: Climate change causes rising sea levels, leading to coastal flooding.
Correct answer: Increased storm intensity from climate change erodes coastlines faster.
Climate change has no effect on coastal ecosystems or landforms.
Climate change only impacts coastal areas by increasing fish populations.
