landforms of emer/submergence

Explain sea level changes

…

Whats a eustatic change

When sea levels change globally

1. Ice caps melting as we all HEGH

2. Thermal expansion = when water gets warmer = expands in volume = increases in sea level rise

Whats an isostatic change

When land rises or falls relative to the sea level and is a localised change

1. Tectonic plates

2. Post-glacial adjustment = when glaciers melted, coastlines raised again as it used to be covered in ice

Explain landforms of emergence

Raised cliffs = former beaches/wcp/caves that have been raised above the sea level

Relic cliffs (Find example

Explain landforms of submergence

1. Rias = flooded river valleys, v shaped

2. Fjord = flooded glacial valleys, U shaped (10x more powerful)

3. Dalmatian coastlines = valley parralel to coastline that becomes flooded = offshore island = Croatia
