Give 2 examples of Variable aspects of a landscape.
Sounds and Storms
Give 2 soft engeneering techinques at the coast.
Beach nourishment and dune regeneration.
Give 3 types of rocks.
Sedimentary, Igneous and Metamorphic
Give 4 hard engineering techinques.
Groynes, Sea wall, Gabions, Rock armour
Give 4 soft engineering techniques to manage floods.
Afforestation, River restoration, Flood warnings, Flood plain zoning
Give the most and least resistant rocks in Britain.
Granite (most) and Clay (least).
Give the Pros and Cons of Beach Nourishment.
Pros: Blends in with beach, Cheap
Cons: Requires constant maintenance
Give the Pros and Cons of Dune regeneration.
Pros: Cheap, Good for the environment
Cons: Takes time, Can be damaged by storms.
Give the Pros and Cons of Gabions.
Pros: Very cheap
Cons: Can be washed away or broken, May cause abrasion.
Give the Pros and Cons of groynes.
Pros: Bigger beach for more tourists, useful for fishermen
Cons: Increases erosion further downstream, Unattractive
Give the Pros and Cons of Rock Armours.
Pros: Cheap and esy to maintain, Efficient
Cons: Dangerous and unattractive, Obtrusive
Give the Pros and Cons of sea wall.
Pros: Effective, Can protect against coastal flooding
Cons: Expenisive, Unnatural
How are beaches formed?
When the swash is stronger than the backwash, depostition occurs and a beach is formed.
How are gorges created?
when the plungepool cuts backwards under the hard rock, the overhang falls and the waterfall moves backwards. After many centuries, the path the waterafll has taken backwards can be seen in the gorge.
How are igneous rocks created?
by the cooling and hardening of magma and lava
How are metamorphic rocks created?
when sedimentary or igneous rocks are put under intense heat and pressure.
How are sedimentary rocks created?
by deposition of organsims and sediment that is then pressurised
How are v-shaped valleys formed?
The river is coming from a steep gradient (high in the mountains) so there is a lot of gravity which helps the water erode downwards. Eventually the river erodes so far down, that the material on the side slides down, making a v-shaped valley.
How are waterfalls created?
There is hard rock and soft rock underneath the river. The soft rock erodes much more quickly causing the river to flow downwards. Eventually, so much soft rock has been eroded, you can see a waterfall.
How do dune regeneration protect the coastline?
The plants prevent some erosion and their roots hold the land together.
How do gabions protect the coastline?
The rocks prevent a lotof the force of the water hitting the cliff.
