Q

explain how the wind is relevant towards the sea

A

waves are formed by wind, moving across the surface of the sea. The distance of open sea over which the wind blows, is called FETCH. Waves with a fetch are stronger

Q

Explain what happens when the shallow water is reached

A

When we reach shallow water, the front of the waves melt the sea bed, causing it to break as it moves toward the shore

Q

Explain backwash and swash

A

When a wave breaks, the water that rushes up the beach is known as the SWASH. The water that runs back down the beach is known as BACKWASH

Q

Explain constructive waves (2)

A

Waves in which the swash is greater than the backwash

But the backwash is weak and cannot carry the sand and stones away again. So the coastline builds up. Typical on calm days

Q

Explain destructive waves (2)

A

Waves in which the backwash is greater than the swash. Destructive waves erode material and carry it away

They have a powerful backwash that can drag stones, sand and people back into the water but their swash is weak

Q

Explain all 3 points on the cliff erosion

A

1) destructive waves crash against the base of the cliff, weakening the rock.

2) a notch is eroded at the base of a cliff over time by the processes of waves erosion. Continued erosion causes the notch to grow

3)the headland hangs overhead until the notch becomes so deep that the overhanging land collapses and falls into the sea

Q

Name the 2 steps for longshore drift

A

1) Waves approach the coast at an angle, due to wind direction, carrying material to the beach.

2) the backwash then carries the material back to sea in a straight line

Q

EXAM ANSWER ON WAVES

A

Waves approach the coast at an angle because that is the direction the wind is blowing. Material is carried towards the coast at this angle by the swash of a wave and then dragged back out to sea in a straight line by wave backwash. This transportation of material up and down the coast in a zig-zag pattern is known as longshore drift

Q

Explain the 5 terms of deposition on beach

A

1) When a constructive wave hits the shore, its strong swash carries small stones and sand up as far as the wave will reach. The wave runs out of energy and deposits its load.

2) itโ€™s weak backwash drags only the smaller, lighter particles back to the sea, leaving the heavier stones higher up the shore.

3) in times of storms, destructive waves will throw much larger boulders and stones to the top of the shore which are left as a storm beach.

4) when the tide is out, the beach sand is dried by the wind and is blown to the back of the beach where it is deposited into sand hills called sand dunes

5) sometimes people plant marram grass to stabilise sand dunes so that they donโ€™t move inland and cover farmland

Q

Sea arch

A

a gap that forms when a cave erodes fully through a headland

28
Q

sea cliff

A

a high, steep feature made of rock and soil that has been eroded back by the sea

29
Q

Blowhole

A

Forms when the roof of a cave is eroded vertically

30
Q

Wave-cut platform

A

a sloping floor of rock extending from the shoreline out to sea

31
Q

sea stack

A

a piece of rock that stands alone in coastal water

32
Q

stump

A

a sea stack that has been worn down by the forces of erosion

33
Q

Deposition definition

A

Deposition refers to when the sea drops or deposits itโ€™s load of eroded material along the coast by the swash of waves

this happens most notably in sheltered bays and inlets where the backwash is not strong enough to drag material back out to sea

34
Q

Managing coastal processes (2+4)

A

The forces of marine erosion, transport and deposition can cause problems for people living in coastal areas

people have learned to protect the coast from erosion and manage transport and deposition in the following ways:
rock armour
sea walls
gabions
groynes

35
Q

Rock armour (4)

A

Rock armour refers to large rocks and boulders that are placed along the coastline to protect against erosion

This armour if often places at the back of a beach

the type of rock used for rock armour is a hard and heavy rock that is resistant to erosion, for example granite

when waves crash against rock armour, they lose energy due to friction

36
Q

Sea walls (4)

A

sea walls are large concrete defence structures built at the back of beaches that experience high level of sea erosion

sea walls are usually built at an angle and may have a curved top to help turn waves back in to see

Sea walls are put in place to prevent erosion by absorbing the strength of crashing waves against the coast

they can also prevent flooding

37
Q

Gaboonโ€™s (4)

A

Gabions are welded wire or mesh cages filled with rocks resistant to erosion

gabions are often stacked on top of one another at the back of the beach

Gabions break the power of a crashing waves and lower the speed of erosion

many people prefer gabions and rock armour to the construction of a sea wall because they fit in better with the local environment

38
Q

Groynes

A

Groynes are wooden or concrete barriers that run along the beach from backshore to forshore

these barriers are place at 90ยฐ to the sea, and their purpose is to disrupt longshore drift and prevent the transportation of material along the beach.

This prevents a buildup of sand at one end of the beach.

39
Q

Headland

A

A headland is an area of hard rock jutting out into the sea

40
Q

formation for bays and headlands

A

The coastline is made up of hard rock and soft rock as waves crashed against the coastline, soft rock such is lime stone is eroded more quickly on the other hand hard rock, such as basalt is eroded more slowly.

41
Q

Name 4 Key reasons why population has increased

A

Improved nutrition- access to better nutrition and a more diverse diet has improved overall health and contributed to increased life expectancy

Falling death rates- advances in e medical science and healthcare infrastructure have resulted in lower death rates.

Urbanisation- as more people moved to urban areas of larger families.

42
Q

NAME ALL STAGES OF POPULATION

A

stage 1- high fluctuating stage

stage 2- early expanding stage

stage 3- late expanding stage

stage 4- low fluctuating stage

stage 5- senile stage

43
Q

Explain stage 1 (3)

A

High birth rate, high death rate

in this stage, both birth rate and death rate are very high

people in this country is usually have large families because many children might of survived adulthood due to diseases, lack of healthcare and other reasons.

This stage is often seen in very poor or pre-industrial societies.

44
Q

Explain stage -2 (3)

A

High birth rate- falling death rate

in the stage, the birth rate remains high, but the death rate starts to decline.

advances in healthcare, better food and clean water. Lead to more people surviving to adulthood.

As a result the population starts to grow rapidly because my babies are being born and few people are dying

45
Q

explain stage 3 (3)

A

Falling birth rate, falling death rate

in the stage, the birth rate begins to decline as people start having fewer children

This decrease in birthrate can be because families want fewer children due to changing social norms, more access to family planning and a desire for better education and living standards for the children,

the death rate continues to remain low or decreases slightly. The population still grows, but not as fast as in the stage two

46
Q

stage 4 (2)

A

Low birth rate low death rate
in the stage, both birth rate and death rate are low

Families tend to have fewer children often just one or two and they usually plan went to have them.

Often associated with more development and prosperous society is population growth is slow and the population tends to stabilise or even decline in some cases

47
Q

Stage 5 (2)

A

Ultra-low birth rate, low death rate

some countries may enter a fifth stage where the birth rate becomes extremely low, and the population starts to decline over time.

this can happen when there are very few young people compared to the elderly leading to challenges in supporting an aging population

48
Q

The 4 bullet points of an expanding population pyramid (thick at bottom and thin at top)

A

High birth rate

Natural increase

Low life expectancy

developing countries eg. tanzania

49
Q
