Formations

Question 1

Formation of levees

Answer 1

Build up of materials that create a natural hill

Question 2

Formation of flood plains

Answer 2

Area of flat land adjacent to a river created to allow water to overflow once bank full conditions are reached

Question 3

Formation of estuaries

Answer 3

Tidal part of river where fresh water from the river merges with salt water from the sea

Question 4

Formation of interlocking spurs

Answer 4

Hard resistant rock that the river cant move so it travels through gaps winding around the, to form spurs and as the process continues the spurs appear to interlock

Question 5

Formation of v shaped valleys

Answer 5

The river erodes downwards and the steap sides are attacked by weathering which loosens the rock. The loosened material creeps down the slope because of gravity.

Question 6

Formation of a waterful

Answer 6

River erodes soft rock away to leave an overhanging cliff which eventually falls off

Question 7

Formation of a spit and a bar

Answer 7

The prevailing wind comes in at an angle creating longshore drift which carries sand and sediment down the beach and is deposited on the headlands which then forms a spit. As the spit gets bigger it grows across a bay joining up 2 headlands

Question 8

Formation of a wave cut platform

Answer 8

1. Land slopes down to the sea freeze thaw ,weathering weakens the rock
2. Wave pounding by hydraulic action and abrasion by shingle hurled at the land erode the base
   3.continued erosion causes rock to break away. Cliff now has a notch as its base. Section of nitch is now unsupported and becomes more precarious as erosion continues
3. Over hanging cliff breaks away and falls onto beach

Question 9

How are sand dunes formed

Answer 9

When the sea brings sediment to the beach and then the wund redistributes that sediment. When the wind encounters the beach, obstacles velocity falls ans the sediment is deposited

Question 10

Formation of a wave

Answer 10

As wind travels over the ocean it causes the water to circulate and forms a wave. As the top overtakes the bottom, it collapses ans hits the main current crashing down. The bottom slows down due to friction while the top keeps its speed causing the wave to break

Question 11

How is a cove formed

Answer 11

Concordant coastline with a hard rocky by the sea. The waves break through and erosion starts taking place behind the hard rock. The soft rock gets eroded away forming a cove

Question 12

Formation of rock fall

Answer 12

Rocks that are prone to freeze thaw can loose control of the cliff face and fall. At the bottom they fan out to form a slope

Question 13

Formation of a rotational slump

Answer 13

A side takes a fairly straight path down a cliff. It is a concave cliff so the material is rotated backwards into the cliff face

Question 14

Formation of a mud slide

Answer 14

The heavier saturated mud falls away along a slip plane which is a line of weakness
