Q

How is an ox-bow lake formed?

A

In a meander, the water erodes the meander neck and soon cuts through. It starts flowing from the shorter route it has formed. The path it used to travel from before is now called an ox-bow lake. The ox-bow lake soon dries up, leaving a meander scar. The land in the middle is called the meander core.

Q

Why are many aged people in countries like Japan wanting to go to jail?

A

This is because they are not getting enough pensions due to the large amount of aged people and they do not have many people to look after them because 1 in 3 people choose NOT to get married or have children.

Q

What is urbanisation?

A

Urbanisation is when a lot of people move from the countryside to the cityside at the same time either forcefully because of natural disasters or by choice in search for better opportunities.

34
Q

Tributary

A

Small streams that join the main channel.

35
Q

Abrasion

A

the material being carried by the river hits the sides and beds of the channel, each impact breaking pieces of the bed and banks.

36
Q

Attrition

A

Rocks and stones in the river bang against each other, chipping bits off so the rocks become more rounded and smaller.

37
Q

Hydraulic action

A

Hydraulic action

38
Q

Corrosion

A

Rocks such as chalk and limestone are dissolved in the river water and carried away as dissolved material.

39
Q

Deposition

A

When a river slows down and no longer has the energy to carry the material it is transporting, It drops some of it.

40
Q

Transportation

A

Movement of a material down a river.

41
Q

Erosion

A

the wearing away of the banks and bed of the river by the power of the flowing water in the channel.

42
Q

How does a waterfall form?

A

A waterfall is formed when hard rock lies on top of softer rock. The force of the water pushes the soft rock in which makes the hard rock unstable and unsupported. So, the hard rock collapses and the process continues. Soon, a valley is formed.

43
Q

The upper course of the river

A

The upper course of the river has less water because it has just started. It often has more energy because of steep grounds and causes vertical erosion.

44
Q

The middle course of the river

A

It has more water and runs off less steep land, so it moves slowly.

45
Q

The lower course of the river

A

The lower course of the river has a lot of water and is deep. It moves slowly and often causes lateral erosion. Soon, the river joins the sea.

46
Q

What is a meander?

A

When the water in a river flows in a curved path.

47
Q

What is a meander neck?

A

The land between the upper and lower arm of the meander bend.

48
Q

What do the contour lines on a map show?

A

49
Q

What is a flood?

A

Flooding is an overflowing of water onto land that is usually dry.

50
Q

What are the physical factors that can affect flooding?

A

What are the physical factors that can affect flooding?

51
Q

What are the human factors that can affect flooding?

A

Urbanisation
Deforestation

52

When water is caught by plants before it reaches the ground while precipitation.

64
Q

Groundwater storage

A

Water stored in the rocks.

65
Q

Permeable

A

A material water can move through.

66
Q

Impermeable

A

A material water cannot move through.

67
Q

Secondary sector

A

People make or build things, often using raw materials from the primary sector for ex. factory workers, house builders, people constructing roads and railways etc.

68
Q

Primary sector

A

Where people take things from land and sea for ex. farmers, fishermen, miners, oil workers, forestry workers etc. They often produce raw materials that other people process.

69
Q

Tertiary sector

A

People provide services for other people for ex. Doctors, Nurses, Teachers, Actors etc.

70
Q

Quaternary sector

A

People use their high-level expertise to help other sectors. For ex. they develop new types of medical treatment (scientists), or new technologies or help companies make financial decisions.

71
Q

Arable farms

A

Where crops are grown e.g. Wheat and Barley

72
Q

Mixed farms

A

Where crops are grown and cattle are kept.

73
Q

Pastoral farms

A

Where animals are raised.

74
Q

Market gardens

A

Where fruits, vegetables and flowers are grown.

75
Q

Why is tourism important?

A

The circulation of money rises the economy. It also offers a lot of jobs.

76
Q

Globalisation

A

The increase links between countries around the world.

77
Q

TNC

A

A company that operates in many countries around the world.

78
Q

What are the different continents?

A

Asia, Africa, North America, South America, Antartica, Europe and Oceania.

79
Q

What are the different oceans?

A

Pacific, Atlantic, Indian, Arctic and Southern ocean.

80
Q

What is a v shaped valley?

A

The river transports the rocks downstream and the channel becomes wider and deeper creating a V-shaped valley between interlocking spurs.

81
Q

Suspension

A

The small transport in the river are light enough to float in the water.

82
Q

Solution

A

Material such as chalk and limestone dissolves in the water.

83
Q

Saltation

A

Heavier rocks bounce on the bed of the river.

84
Q

Traction

A

When the river is flowing over steep land and has a lot of energy, it makes the very heavy rocks roll on the bed of the river.
