Changing Coastlines
These have a strong backwash and carry out erosion to create a steep and narrow beach.
What are destructive waves?
When more resistant rock juts out on either side of a bay it forms these.
What are headlands?
describing the temporary movement of people primarily for leisure or recreational purposes.
What is tourism
What causes waves?
What is Wind dragging on the surface of the water.
The removal of material from coasts causing it to wear down
What is erosion?
The process of waves crashing into cliffs, compressing trapped air and breaking the rock.
What is hydraulic action?
Lines of weakness, such as joints and notches, are increased in size by erosive waves, eventually becoming this
What is a cave?
Where most of the Earth's coral reefs are found
What is the Great Barrier Reef in Australia (100 BONUS points if you are able to describe the location/distribution of coral reefs)
The length of water the wind bows over and the distance waves travel
What is fetch
the area where the coast meets land
What is shoreline
When particles carried by waves crash into each other and break them down into smaller, rounded particles.
What is attrition?
Most coastal depositional landforms are caused by this process.
What is longshore drift?
The world's top 6 aquaculture producers of fish belong to this region
What is Asia (100 bonus points for naming the top 2 producers)
When waves break and moves up a beach carrying sediment with it.
What is swash
Name of a structure that slows down longshore drift
What is groynes (100 points for drawing how the structure looks and works)
Occurs when the sea piles up sand and pebbles to form new land.
What is deposition?
This landform occurs when a beach or sand spit joins up with an offshore island.
What is a tombolo?
the ideal environmental conditions for coral reefs to grow
What is shallow warm waters (not more than 50m in depth, temperatures not lower than 17-18degree celsius)
When waves change direction as they approach a coast
What is wave refraction (100 BONUS points for telling me WHY they change direction)
The lowest part of a wave
What is the trough
Acids in seawater dissolve the chalk and limestone cliffs in this process.
What is solution or corrosion?
Put the following features in the right order. Stump, stack, cave, arch.
