Submergent And Emergent Coastline - COASTS

Question 1

Emergent coastlines example due to isostatic (rise/fall in land)

Answer 1

Raised beaches - kings cave

Question 2

Submergent coast landforms due to eustatic (rise/fall in sea level due to volume of water )

Answer 2

• Rias - kings bridge estuary in Devon
• Fjords- Norway
• Dalmatian coasts - Croatia

Question 3

Isostatic change meaning

Answer 3

Land moves in relative to the sea

(crustal material is forced down into the mantle changing the relative sea level.)

Question 4

Eustatic subsidence meaning

Answer 4

Sea moves in relative to the land

(a rise or fall in water levels caused by a change in the volume of water.)

Question 5

Formation of fjords

Answer 5

Glacial troughs ( U- shaped valleys ) are flooded due to rising sea levels.

Question 6

Formation of Dalmatian coasts

Answer 6

Mountains run parallel/concordant to coast and submergence of this coastline produces long inlets with a can of parallel islands

Question 7

Formation of Rias

Answer 7

A ria is a drowned river valley - a section of river valley flooded by the sea, making it much wider than would be expected based on the river flowing into it

Question 8

Formation of raised beaches

Answer 8

Originally a beach or cliff created through rising sea level
