Coasts

which of these are costal erosions ?

• sea wearing away the land

• how the waves are created

• waves crashing into the shore

select 4 proccesses of costal erosion?

• hydralic action

• attrtion

• abrasion

• corrosion

• nutrition

hydralic-action is......

• where large rocks collide causing them to break down into the smaller rocks

• where acids in the water disslove the cliff

• where waves pick up rocks and hurl them at the cliff causing it to break down the rock

• where waves push air into cracks in the cliff trapping air forcing it slowly war and break apart

corossion is ......

• where large rocks collide causing them to break down into the smaller rocks

• where waves push air and water into cracks forcing the air into the hole forcing it to break apart

• where waves pick up rocks and hurl them at the cliff causing them to break down

• where acids in the water disslove the cliff

bays are formed because.....

• they are made up of soft rock, which erodes faster than hard rock

• they are made up of hard rock which erodes slower than soft rock

define the term'deposition'

• the dumping of sand and minerlas on a coastline

• the bulid up of land through deposits of sand and other materials

do aboriginal and torres strait islanders communites have coastilne managment stratergies?

• yes

• no

identify two natural forces that can change coastal managment

• wind and fire

• fire and water

• water and wind

• wind and air

why are sea walls built along our coast?

• to reduce deposition

• to reduce erosion

• to provide sfae swimmig are for peolpe visting the coastline

• so our ships have a safe pasage along our coastline

constructive waves contribute in creating...

• cliff landforms

• oceans

• erosinal landforms

• depositional land forms
