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
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
Diapositiva 3
Deposition
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

examples of global warming
what causes it ?
carbon dioxide- burning fossil fuels
methane - cows
nitrogen- burning fossil fuels Effects
effects of global warming are social and environmental changes caused (directly or indirectly ) by human emissions and greenhouse gases
HUNGER - Not having enough food to satisfy hunger
STARVATION- People die because not having enough food to eat
FAMINE- When supplies (crops ) go after long period of time
MALNUTRITION- Not getting enough food or varied food
OVERCONSUMPTION- When you eat to much it causes obesity
FAIR TRADE- All money used to by beans goes straight to farmers and they're community
(remember developed and undeveloped countries)
Earthquake - a violet shaking of the earths surface
tsunami - earthquake under sea makes massive wave
RESPONCE TO TSUNAMI
Short term-days medium term - weeks , months long term - months years
PREPARE FOR TSUNAMI
Emergency supplies evaluate plan warning signs
spot signs
tsunami
