- Sea-level Rise
- Sea Level change......
- over time it has risen and fallen fluctures
- The sea is tidal so it becomes high and lower during the day
- Links to ice age and major global events
- Hydrological Cycle
- Closed System
- fixed quantity of water on Earth
- this changes state to..
- Solid (Ice)
- Liquid (Water)
- Gas (Water Vapour)
- this changes state to..
- fixed quantity of water on Earth
- Closed System
- Types of Changes
- Eustastic
- Water changing in relation to land
- Alteration in volume in the ocean
- Fall in sea level = will fill up again after an ice age (this take place during and after)
- Isostatic
- Land changing in relation to the sea
- Links to tectonic change of the ocean basin
- Eustastic
- Key Terms
- Emergence
- the impact of relative fall in sea level
- Emergent Landorms
- Raised beaches and are developed above sea level
- E.g. Aaran, West Scotland
- Raised beaches and are developed above sea level
- Submergence
- the impact of a relative rise in sea level
- Submergent Landforms
- Water floods the land & fills up
- Rias
- typical river valley but have more water
- cross section of a Ria
- For lower course -> floodplain gets flooded
- Coastal inlet formed by the partial submergence of an un-glacial river valley
- Dendritic -> can be straight without tributries
- Fjords
- steeper & deeper variants of Rias
- have 'U' shaped cross section
- deeper inland than to mouth
- due to glacier deposited its load
- e.g. Sognefjorde
- Dalmatian Coast
- valleys lie in parallel to each other
- flood due to the rise in sea level
- Croatia
- valleys lie in parallel to each other
- Emergence
- Sea Level change......
