- WEATHERING ~
- Physical weathering ------weathering and breakdown of rock by weather
- Biological weathering -----breakdown of rock by plants and animals
- Chemical weathering------erosion is the disintegrating of rocks
- EROSION ~
- Corrosion ----- rocks are hitting against the cliff edge
- Attrition ------- Rocks are hitting against each over and go small and round
- Solution-------- dissolved by slightly acidic water
- Hydraulic action - force of water
-
headlands , bays , transport and waves
- CONSTRUCTIVE WAVE ~
- Long wave length strong swash weak backwash low energy
- DESTRUCTIVE WAVE ~
- weak swash strong back wash erodes sand high energy
- TRANSPORT IS.....
- Traction-rolling rocks Saltation-bouncing smaller rocks
- Suspension-particles carried by water
- Solution-dissolved
-
- when certain conditions arise the sea can no longer maintain its energy and drops any material its carrying such as sand pebbles and rock materials
-
- GREEN HOUSE EFFECT ~
- is the Process by which radiation atmosphere warms the planet to a temperature what it would be without its atmosphere if a planet contains active gases they will radiate energy in all directions
- ENHANCED GREEN HOUSE EFFECT ~
- Refers to human activity that are adding to the warming of the earths surface due to the greenhouse effect the presence of gases increase the worlds heat by adding to the heat from the sun
-
