sea level rise

global changes

rapid change

a rise or fall of the sea level

local changes

slow changes

a rise or fall of the land depending on the sea level

eustatic

isostatic

global ice melt

sea level changes in response to amount of water stored in ice caps

thermal expansion of water

changes in temperature of water = sea water expands at higher temperatures

weight of ice

land rebounds after ice has melted = new mountains and hills

emergence: a fall of sea level that exposes land normally covered by the sea

raised beach

high energy coastline

wave action occurs at water line

change in sea level rapidly (fall in levels)

leaves behind a partly eroded cliff face and long extension of land in front before the sea

marine terraces

a raised beach formation that occurs continuously = many small cliff faces with a wave cut notch underneath

submergent: a rise in sea level flooding a coastline and creating a submerged area. beaches, spits and other landforms disappear under water

ria

a river valley becomes flooded leaving behind a flooded landscape of dotted lands (higher land remains dry but valley is flooded)

fjord

a u shaped valley becomes flooded (high land remains but low lying land in the valley is submerged in water)

dalmatian coastline

a glacial valley is adjacent to the coastline and floods to form dotted round circles of higher land that stick out from the submerged area
