Q

A
  • It is expensive to protect the area and rebuild after a disaster.
46
Q

How did climate related diseases and pests cause the development gap?

A

Can destroy a countries livestock and are premature deaths in humans reducing the workforce.

47
Q

How does the supplies of clean water cause the development gap?

A

Having to travel to get clean water results in less time to work and go to school.
Dirty water can cause illness and gain impact on the economy.
This could cause both human and physical. In areas with low rainfall it is a physical feature but in some areas it is a human issues due to lack of adequate infrastructure.

47
Q

How did manufacturing issues cause the development gag?

A

Many low income countries rely on manufacturing to make money. This is often low skilled and low paid. The rich countries keep the costs down by making products in LICs and NEEs and the profit returns to the HICs.

47
Q

How does struggles with gaining independence cause the development gap?

A

As LIC and NEE countries were often once colonies they can struggle with gaining independence. This can lead to civil wars and struggles for power. Corrupt political system and fallout from war can have a devastating impact on a countries ability to develop its own economy.

48
Q

How does exporting primary products cause the development gap?

A

Exporting primary products tends to be one of the ways in which LIC countries make money. This is a volatile market and prices rise and fall very often. This makes it difficult to develop as they are unsure of future profits.
Also supply and demand for raw materials.

49
Q

What is bottoms up aid?

A

Aid/development funded and carried out by NGOs in co-operation with local communities.

50
Q

NGOs

A

Non - Government Organisation

51
Q

What do NGOs do?

A

NGOs ask local communities what they want to ensure they meet their needs.

52
Q

What is the goat aid in Tanzania do?

A

After talking to villagers about their needs Farm Africa and NGO imported goats costing £400 each. In total £200, 000 was invested. This occurred between 1999 and 2006. Toggenburger goats were choose because they produce 3 litres of milk a day. The owners were trained on how to care for the goats.

53
Q

What are the advantages of Toggenburger goats?

A
  • Provides milk which can improve people’s health and ability to go to school and work.
  • Manure can be used as fertilizer which improved crop yields and meant farmer could sell excess and make more money.
  • Goats bread more easily which means they can be sold for money.
  • Milk can be made into cheese and butter to be sold.
54
Q

What are the disadvantages of Toggenburger goats?

A
  • Goats require lots of water which is scare.
  • Goats hooves and grazing can lead to over gazing and lead to desertification.
  • Vet bills can be expensive.
55
Q

Why are food, energy and water the most important resources in the world?

A

Some LICs have resource insecurities because their lack of food, water or energy is preventing them from developing. Their resource security in HICs, which enables them to make money and for people to have a good standard of living.

56
Q

Rescources

A

Something that have a value or purpose, such as food, water or energy.

57
Q

Resource insecurity

A

Lack of resources like food, water and energy.

58

Q

What is the composition of the continental crust?

A

63
Q

How dense is the continental crust?

A

Less dense

64
Q

Tell me about the inner core.

A

The inner core is at the centre of the Earth. It is made up of solid metals - mostly iron and nickel. It is also the hottest part of the Earth, with temperatures reaching 5500 degrees Celsius. With this immense heat energy, the inner core is like the engine room of the Earth.

65
Q

Tell me about the outer core.

A

The outer core surrounds the inner core. It is a liquid layer, made up of iron and nickel. This layer is still extremely hot, with temperatures similar to those found in the inner core.

66
Q

Tell me about the mantle.

A

The mantle is the widest layer of the Earth, with a thickness of approximately 2900 kilometres. The mantle is made up of semi-molten rock called magma. In the upper parts of the mantle the rock is hard, but lower down the rock is soft and beginning to melt.

67
Q

Tell me about the crust.

A

The crust is the outermost layer of the Earth. This is a thin layer, between 0-60 kilometres thick. This is made up of solid rock, and is the layer which we live.

68
Q

Why do the Earth’s tectonic plates move?

A

The theory of convection suggests that magma is rising in the mantle as it is heated and then sinks back towards the core when it cools.

As the currents move beneath the plates they build up lateral pressure and carry the plates with them.

69
Q

What is a tectonic plate?

A

A large section of the earth’s crust.

70
Q

What is an oceanic crust?

A

Thin and dense.

71
Q

What is a continental crust?

A

It is thick and less dense than the oceanic crust.

72
Q

What are the two main types of tectonic plates?

A
  • Oceanic crusty
  • Continental crust
73
Q

What causes an earthquake?

A

It is caused by rocks suddenly shifting.

74
Q

What causes a volcano?

A

Forms when liquid rock bursts out through Earth’s hard surface.

75
Q

Constructive plate boundaries

A

= As two plates move apart, new oceanic plates are constructed.

  • You get
    - volcanoes
    - Small earthquakes.
  • e.g.
    - Mid-Atlantic Ridge
76
Q

Destructive plate boundries

A

= Plate is destroyed - Oceanic plate is subducted down into the mantle.

  • You get
    - Violent volcanoes
    - Enormous Earthquakes
  • e.g.
    - Nazca plate
    - South American plate
77
Q

Conservative plate boundaries

A

= Two plates moving past each other either different directions or different speeds.

  • You get
    - No volcanoes
    - Earthquakes
  • e.g.
    - San Andreas, California
78
Q

Collision plate boundries

A

= Two continental plates meet. Same density, so no subduction. Two plates push up when they collide.

  • e.g.
    - No volcanoes
    - Earthquakes
79
Q

What is a focus?

A

The point of origin of the earthquake.

The place in the Earth where rocks were moving.

80
Q

What is the epicentre?

A

The point on the Earth’s surface directly above the focus.

The point at the strength above the focus.

81
Q

What is a seismic wave?

A

Energy released by the Earthquake.

82
Q

What is the richer scale?

A

The scale on which the strength of the Earthquake is measured.

83
Q

What does magnitude mean?

A

How strong an Earthquake is.

84
Q

What is an after-shock?

A

Small Earthquake after the main large one.

85
Q

What is a seismometer?

A

An instrument to measure the strength of an Earthquake.

86
Q

How do Earthquakes happen?

A
  1. Earthquakes occur at the plate margins.
  2. As the plates move past each other at the margins the movement is not smooth.
  3. The plate sometimes lock, causing pressure to build up.
  4. This pressure is suddenly released in a jerky movement.
  5. This release of pressure is called an Earthquake.
87
Q

What is formed by convergent plate boundries?

A
  • Mountains
  • Trenches
  • Volcanoes
88

A
  • The core
  • The mantle
  • The crust
92
Q

What does the plate tectonic theory show?

A

That they Earth’s crust is split into plates.

Small areas where Earth’s crust that hot magma melts and breaks the rock above it, often building up over time to form an island.

104
Q

What happens inside a volcano?

A

Deep below the grounds surface is a magma chamber. Magma rises through a pipe called the vent. At the top of the vent is a volcanic crater. Magma reaches the ground surface to form lava which flows down the sided of the volcano.
