sea level change

• eustatic sea level change refers to the change in sea level whereas isostatic sea level change refers to the change in land level
• 2 examples of eustatic sea level change is increased temps causing melting of ice sheets increasing sea level and thermal expansion

  another example is sea level decreasing due to decreased temperatures as precipitation turns into snow
• 4 examples of isostatic sea level change?

  post glacial adjustment

  subsidence

  accretion

  tectonic activity
• emergent coastlines form from sea level fall
• 2 emergent coastline landforms are raised beaches and fossil cliffs
• 3 submergent coastline landforms are rias, fjords and dalmatian coastlines
• one reason for sea level change and how it affects the coastline?

  global temperature rising leading to increased sea level through melting of cryosphere and thermal expansion

  this affects the coastline as low lying coastal areas are prone to floods
