Q

Development gap

A

The difference in levels of development between the richest and the poorest countries in the world. The difference between HICs and LICs is getting wider.

Q

Investments can help close the development gap?

A

Large companies can locate part of their business in other countries. This helps a country to develop as the companies build factories, lay roads and install internet cables.

Q

Aid can help close the development gap?

A

Aid is when one or more countries give money to other countries. The money has to be spent on things that will benefit the population.

Q

Using intermediate technology can help close the development gap?

A

Intermediate technology is using equipment and techniques that are suitable for their country of use. Many poorer countries do not have the skills to maintain expensive equipment. Small-scale, basic solutions are usually more appropriate.

Q

Fairtrade can help close the development gap?

A

Fairtrade is paying producers a reasonable price for the goods that they produce. Many farmers in LICs are paid very low wages. This means that they cannot escape poverty. Fairtrade gives farmers a better chance in life.

Q

Debt relief can help close the development gap?

A

Many LICs owe money to other countries. Often the repayments and interest are so expensive that indebted countries have no money left to spend on development projects. Debt relief is when debts are either reorganised to make them more manageable, or reduced.

Q

Microfinance loans can help close the development gap?

A

Microfinance loans are when money is lent to LICs to help them to develop. These are often small loans with reasonable interest rates. They are available to people and businesses who may normally struggle to get credit.

Q

The crust

A

It is made from enormous plates which move very slowly due to movements of the mantle below.
It is the outmost 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 upon which we live.

Q

The Mantle

A

The mantle is the widest layer of the Earth with the thickness of approximately 2900 kilometres. The mantle is the 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.

Q

The inner core

A

It 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.

Q

The outer core

A

It 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.

Q

How do the Earth’s tectonic plates?

A

The theory of convection suggests that magma is rising in the mantle as it is heated and then goes 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.

25
Q

Oceanic crust

A

The part of the Earth’s crust that makes up the seafloor. It’s thinner, denser, and simpler in structure than the continental crust.

26
Q

Continental crust

A

The outermost layer of Earth’s lithosphere that makes up the planet’s continents and continental shelves and is formed near subduction zones at plate boundaries between continental and oceanic tectonic plates. It is Thicker and less dense than Oceanic curst.

27
Q

What are the two main types of

A
  • Oceanic crust
  • Continental crust
28
Q

Earthquake

A

Caused by rocks suddenly shifting.

29
Q

Volcano

A

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

30
Q

Where are most Earthquake and volcanos?

A
  • They tend to lie along lines.
  • Are often together.
  • Occur in the ocean as well as on land.
31
Q

Why do tectonic plates move?

A
  1. Plates are slabs of the lithosphere - Earth’s hard curst and upper mantle.
  2. They float on the soft hot rock below.
  3. They move because they’re dragged by the powerful hot currents- convection currents - in the soft hot rock. (Other factors play a part too. Scientists are still researching these.)
  4. They move just a few cm a year - but it all adds up.
  5. For example India had moved 2000km north in the last 70 million years.
32
Q

Lithosphere

A

Earth’s hard curst and upper mantle.

33
Q

Convention

A

In the soft hot rock. (Other factors play a part too. Scientists are still researching these.)

34
Q

What plate is moving north?

A
  • Indo-Australia Plate
  • African Plate
35
Q

What is a plate that carries just ocean?

A
  • Pacific Plate
  • Nazca Plate
  • Philippine Plate
36
Q

What plate is circled around the Rind of Fire?

A

Pacific Plate

37
Q

Constructive Plate Boundaries

A

= As two plates move apart, new oceanic plate is constructed.
- Have
- Volcanoes
- Small Earthquakes
- e.g.
- Mid - Atlantic Ridge

38
Q

Destructive Plate Boundaries

A

= Plate is destroyed - Oceanic plat is subducted down into the mantle.
- Have
- Violent Volcanoes
- Enormous Earthquakes
- e.g.
- Nazca
- South American Plate

39
Q

Conservative Plate Boundries

A

= Two plates moving past Each other either different directions or different speeds.
- Have
- No Volcanoes
- Earthquakes
- e.g.
- San Andreas, California

40
Q

Collision Plate Boundries

A

= Two continental Plates meet. Two plates push up when they collide
- Have
- No Volcanoes
- Earthquakes

41
Q

Focus

A

The point of origin of the Earthquake.

The place in the Earth where rocks were moving.

42
Q

Epicentre

A

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

43
Q

Seismic waves

A

Energy released by the Earthquake.

44
Q

Richer Scale

A

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

45
Q

Mafnitude

A

How strong an Earthquake is.

46
Q

After-shock

A

Small Earthquake after the main large one.

47
Q

Seismometer

A

An instrument to measure the strength of the Earthquake.

48
Q

How do Earthquakes happen?

A
  1. Earthquakes occur at plate margins
  2. As the plates move past each other at the margins the movement is not smooth.
  3. The plates 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.
