Q

Tree rings

A

The light-colored rings represent wood that grew in the spring and early summer, while the dark rings represent wood that grew in the late summer and fall. One light ring plus one dark ring equals one year of the tree’s life. The color and width of tree rings can provide snapshots of past climate conditions.

Q

Process of hurricane being formed?

A
  1. warm air currents rise from the ocean, as it rises more air rushes to replace it
  2. updraughts of air contain huge volumes of water vapour from the oceans which condense to produce cumolonimbus clouds
  3. coriolis force causes rising currents of air ti spiral around the centre of the tropical cyclone so it resembles a whirling cylinder. Some of it descends to form the clear, still and cloudless eye of the storm
  4. as it tracks away from its source it is fed new heat and moisture which makes it more powerfull
  5. Once it reaches a landmass it loses its energy source from the ocean. Air pressure rises as temperature falls. Winds drop, rainfall decreases and it decays to become a more storm

Q

What is the evidence for continental drift?

A

fossil evidence and places like india looking like they were once part of a larger body of land

54
Q

What is subdutction

A

enser oceanic crsut sinks below continental crust at a convergent plate boundary. THhe subducted crust melts and new crust is formed at divergent plate boundaries which means the age of the crust varies greatly.

55
Q

Why is inner core solid

A

Intense gravity and pressure

Patterns in evaporation and precipittation and lower salinity at equator then increases then decreases towards polls

67
Q

Salt water means

A

Denser

68
Q

What else can cause earthquakes?

A

● Tsunami can be caused by landslides (1) which causes water to be
displaced generating waves. (1)
● Tsunami can be caused by underwater volcanic eruptions (1) which
causes water to be displaced giving large waves. (1)
● Tsunami can be caused by large meteor strikes (1) which displaces
large quantities of water causing large waves. (1)
● Upward movement of a tectonic plate (1) causing the movement of
water. (1)
● The movement of plates (1) causes friction to occur (1)
● Earthquakes (1) transfer energy to the water causing it to move

69
Q

Natural causes of climate change/

A

Volcanic eruptions (1) cause cooling as incoming solar radiation is
blocked by volcanic dust. (1)
● Asteroid collisions (1) can cause cooling as large quantities of ash and
dust to be kicked up into the atmosphere. (1)
● Increased/decreased sunspots/solar flare activity (1) cause
warmer/cooler periods as more/less solar energy is released towards
the earth. (1)
● Changes in the earth’s orbit / Milankovitch cycles (1) can cause
cooling or warming of the earth as the amount of solar radiation
received by earth varies. (1)
● Volcanic eruptions (1) can lead to a warming of the earth as more

87
Q

Why do projections of sea levels vary?

A

● Humans may adopt more renewable energy sources (1) which will
lead to less global warming and less sea ice melt (1).
● Future rates of economic development are difficult to predict (1)as
countries develop they may either reduce or increase their emissions
(1).
● Future rates of population growth are uncertain (1) so a reduced
rate of growth may lead to less global warming and lower sea level
rise (1)
● There could be an increased volcanic activity (1) which may result in
lower sea level rise nearer the 20cm lowest projection. (1)
● A rapid increase in fossil fuel use (1) could cause a 200 cm increase
(1).
● The process of climate modelling may have inaccuracies (1), it is
difficult to make accurate future projections as there are so many
variables (1).

91
Q

Suggest one way in which systems of governance can cause inequaliti

A

Open economic policies (1) encourage foreign investment
which leads to faster development (1) which benefit some
groups e.g. those who are employed (1).
● Colonialism (1) resulted in colonies being exploited for the
economic gain of colonial powers (1) with unequal trading
relationships established (1).
● Gender bias within governments (1) may result in widening
inequalities between men and women (1) which leads to pay
differences (1).
● Government policy which focus on development in specific
regions (1) increases inequalities between wealthy / poor
regions (1) for example the investment in new infrastructure in
urban areas (1)
● Racial bias within governments (1) negatively effects certain
ethnic groups (1) which has led to the persecution of people for
their religion
High levels of corruption often correspond to low levels of
development (1). In such countries, public finances may not be
used effectively (1) limiting spending on public services such as
schools and hospitals (1).
● In countries where corruption is high, government officials
may make poor decisions regarding public finances (1). A lack
of investment in health services (1) may result in lower life
expectancies (1).
● Countries where governments have invested in
education/healthcare tend to develop faster (1). A
healthy/educated population encourages investment (1) and the
workforce more able to contribute to economic growth (

92
Q

) Explain one disadvantage of intermediate technology

A

Intermediate technology does not often benefit a large number
of people (1) so may not have much of a positive impact on an
area’s quality of life (1).
● Micro-hydroelectricity can be an unreliable form of power (1)
because of variations in rainfall. (1)
● Intermediate technology often does not have direct
government support (1), therefore may incur financial
difficulties (1).
● Intermediate technology often still involves some cost / some
can’t afford it (1) whichmeans not all of the community will be able
to benefit (1).
● Intermediate technology can be unreliable (1) requiring regular
repairs (1).
● Intermediate technology is not well suited to address issues at a
national scale (1) such as transport and communication
infrastructures

93
Q

How does FDI’s benefit emerging countries

A

FDI increases the number of jobs (1) which leads to an increase in
tax revenue for the government (1).
● FDI creates jobs (1) which, in turn, leads to the population
learning new skills (1).
● TNCs invest in local infrastructure (1) which can benefit
existing local industries (1).
● FDI may introduce new technologies (1) that can help further
development for ‘local’ businesses.
● FDI leads to the multiplier effect (1) leading to further economic
development

94
Q

Explain two negative impacts of the rapid economic development of an emerging
country on different age group

A

Air pollution (1) leads to breathing problems amongst the elderly
/ young people (1)
● Often there are not enough jobs leading to unemployment for
young people (1) as a consequence of rapid rural to urban
migration (1)
● Rapid rural to urban migration (1) leads to an ageing population
in rural areas who have no-one to look after them (1).
● TNCs in emerging countries are known to employ young children
resulting in them not attending school (1) and their education
suffering as a consequence (1).
● Rural to urban migration (1) leads to an inactive ageing population
in rural areas who are often economically inactive (1

97
Q

) Explain two ways in which changes in the area of Arctic ice may have
consequences for people.

A

Melting Arctic ice will lead to rises in sea levels (1) which may result
in coastal flooding (1).
● Melting ice can lead to the destruction of animal habitats (1) which
people rely upon to provide food and furs (1).
● Melting sea ice can have an effect on ocean circulation (1) potential
leading to climate changes (1).
● Melting Arctic ice can result in the release of methane from
permafrost (1) leading to further global warming (1).
● Unstable ice can lead to difficulties when fishing (1) leading to
injuries and death (1).
● Melting ice leads to transport becoming difficult (1), isolating
communities (1).
● Decreasing Arctic ice can lead to an erosion of indigenous cultures
(1) as traditional sources of employment are replaced by work in the
oil/gas industry (1).
● Early spring ice melting will give a longer fishing season (1), this will
lead to increased incomes for indigenous people (1).
● Melting Arctic ice opens new shipping routes (1), boosting trade and
being a source of employment in Arctic towns (1).
● Reduced Arctic sea ice coverage will lead to increased oil
exploration in the area (1), this will provide a source of employment
for local people (1).

98
Q

) Explain two reasons why tropical cyclones lose their energy

A

marks for each explanation.
● When tropical storms reach land (1), they no longer have access to
warm water which is their source of power (1).
● Tropical storms lose energy when they move into areas of cooler
water (1). They require water with a temperature of above 26.5
degrees Celsius (1).
● They lose energy when they meet different weather systems (1)
where winds are blowing in the different directions / wind shear is
high (1)

99
Q

People affected by aila

Q

Maternal mortality rate

A

The annual number of deaths per 100 000 women whilst pregnant
or in childbirth

101
Q

) Explain one reason why fertility rates fall as countries develop

A

Improving education/literacy levels in women (1) improves knowledge of birth control
methods (1).
● As female education improves (1) women are more likely to have opportunities for
careers/employment (1).
● More money Is spent on birth control programmes (1) educating the population about
the advantages of having smaller families (1).
