Section A
Answer ONE question from this section.
1. (a) Fig. 1A (INSERT) shows the distribution of volcanoes around the world.
(i) With reference to Fig.1A, describe the distribution of volcanoes around
the world. [3]
(ii) Explain how volcanoes can be a real threat to the communities living near
its vicinity. Use examples to support your answer. [4]
(b) Fig.1B (INSERT) shows the formation of various landforms as a result of plate
movement between the African Plate (Somolian) and African Plate (Nubian).
With the help of a well labelled diagram, explain the formation of the landforms
as a result of the movement of plates along the African Plate (Somolian) and
the African Plate (Nubian). [5]
(c) Fig. 1C shows an extract from an online news article regarding an earthquake that
hit Ecuador’s northwest coast on 10 Jul 2016.
The quake was centered near the town of Esmeraldas, northwest of the capital
Quito, at a shallow depth of about 35 km (22 miles), the USGS said. The Pacific
Tsunami Warning Center did not issue a tsunami warning immediately after the
quake.
President Rafael Correa said authorities had not received any reports of casualties
or material damage. "We must remain calm," Correa said during a telephone call to
a state-run television station."These are normal replicas, though the fear that people
feel is understandable - especially the victims of the April 16 quake."
The tremor was felt in Quito and the coastal business hub of Guayaquil, with
residents streaming out of buildings into the streets, according to witnesses. The
coastal region has been hit by a series of quakes since the April 7.8 tremor that
killed more than 650 people, the nation's strongest quake in decades.

the help of a well-labelled diagram, explain the formation of this type of
rainfall. [4]
(b) Fig. 2B (INSERT) shows some facts about global warming.
With reference to Fig.2B, explain two negative impacts that global warming will
have on human settlements along the coasts. [5]
(c) Fig. 2C shows a news extract regarding an earthquake that took place in the south
Taiwanese of Tainan, Taiwan on 5 Feb 2016.
A 35-year-old woman described how she and her two children were pulled from the
rubble.
"Rescue workers broke through (the building) layer by layer. And they asked us to
climb out but I said my children are too small to climb. So they dug a bigger hole.
Then one rescue worker tried his best to climb in and take the children out. Then I
slowly climbed out myself," she said.
There have also been at least five aftershocks. The quake was felt in the capital
Taipei, 300 km away. Although the damage does not appear to be widespread, a
number of tall buildings have been left leaning precariously.
There are also reports of power outages, and transport links have been disrupted on
what is one of the busiest travelling days of the year ahead of the Chinese New Year
holiday.

man, Canada, 2008)
It's so easy to lose everything you’ve got because you disclose your information
and then it goes like a domino ...and then what you gonna do? Can’t get a job,
can’t get a girlfriend, can’t do nothing.(Heterosexual man, Michigan, United States,
2009)
I’d been openly taking my pills in front of this guy I’d been seeing for weeks. I
assumed he knew my HIV status. When I said I was off to my HIV doctor that
afternoon it suddenly became apparent that this was not the case. He thought it
was not polite to ask what the pills were for... and hadn’t even thought they might
be for HIV. (Gay man, Australia, 2005)

Suggested Mark Scheme
1. (a) Fig. 1A (INSERT) shows the distribution of volcanoes around the world.
(i) With reference to Fig.1A, describe the distribution of volcanoes around
the world.
- Volcanoes are found near convergent and divergent plate
boundaries.
- Most of the volcanoes are found near convergent plate
boundaries, such as between the Indo-Australian and
Eurasian plates, and the Pacfic plate (Pacific Ring of Fire).
- Some volcanoes can also be found near divergent plate
boundaries, such as between the African and North/South
American plates.
- A few isolated volcanoes can be found away from plate
boundaries, but on locations known as “Hot spots”, such as
Kilauea and Mauna Loa, in the middle of the Pacific plate.
[3]
(ii) Explain how volcanoes can be a real threat to the communities living near
its vicinity. Use examples to support your answer.
- Destruction by volcanic materials
o Volcanic materials, such as lava and rock fragments,
produced by volcanic eruptions can lead to widespread
damage of property when they burn the areas they flow
through or fall on.
o An example is the ongoing eruption of Kilauea in
Hawaii, USA since 1983, which have destroyed many
homes and highways.
- Landslides
- Pollution
- Effects on Weather
[4]
(b) Fig.1B (INSERT) shows the formation of various landforms as a result of plate
movement between the African Plate (Somolian) and African Plate (Nubian).
With the help of a well labelled diagram, explain the formation of the landforms
as a result of the movement of plates along the African Plate (Somolian) and
[Turn Over 9
10. the African Plate (Nubian).
- When the African Plate (Somolian) and African Plate (Nubian)
diverge or move apart, they are stretch, causing fractures to form
at the plate boundary.
- The land in between the two continental crusts sinks, forming a
linear depression known as a rift valley.
- Rising magma might escape from the fractures caused by the
movement and erupts onto the Earth’s surface, and overtime, cools
and accumulate to form volcanoes.
- In this case, the East African Rift Valley, along with a number of
volcanoes and earthquake fractures, was formed.
[5]
(c) Fig. 1C shows an extract from an online news article regarding an earthquake that
hit Ecuador’s northwest coast on 10 Jul 2016.
Using examples from Fig. 1C and other studies you have made, explain two
factors affecting the impact of an earthquake.
- Magnitude of earthquake
o Magnitude of earthquake refers to the amount of energy
released and is often measured using the Ritcher Scale.
o For each increasing magnitude on the Ritcher Scale, the
impact of the earthquake is 10 times greater than the
previous one,
o thus with a magnitude of 7.8, the earthquake in Fig.1C is
likely to cause severe damage.
- Population density
- Level of preparedness
- Distance from epicentre
- Depth of focus
- Time of occurrence
- Type of soil
[5]
(d) “Short term responses are more effective in reducing the damage caused by
an earthquake than long term ones.” To what extent do you agree with the
statement? Give reasons to support your answer.
Possible Content:
Agree because
- Short term responses are those that occur immediately and last for
weeks after the occurrence of an earthquake, and focuses on
managing the impacts of an earthquake to minimise the casualties
and damage.
- Handling the status of the affected area
o When

- Providing medical aid, food and water
- Setting up emergency shelters
- Calling for humanitarian aid
Disagree because
- Long term responses can stretch over months and years and
involve rebuilding an affected region.
- Improving infrastructure
o With
- Compensating people who lose their land and property
- Ensuring the affected region recovers economically
- Improving health options

2. (a) Fig. 2A (INSERT) shows the climograph of a country in the tropics.
(i) Identify the type of climate experienced in this country and describe the
features of this climograph.
- Tropical equatorial climate
- The country experiences high mean annual temperature of
~26.5°C
- The country experiences a small annual temperature range of
2°C
- The country experiences high total annual precipitation of
2705mm
- The country experiences precipitation that is evenly

precipitation recorded every month.
(ii) Places such as those in Fig.2A typically experience a type of rainfall. With
the help of a well-labelled diagram, explain the formation of this type of
rainfall.
- Convectional rain occurs when the earth’s surface is heated
intensely, causing the air around the surface to be heated up.
The air becomes unstable, expands and starts to rise.
- As the air rises, its temperature starts to drop and upon
reaching dew point, starts to condense into cumulonimbus
clouds.
- When the water droplets in the clouds become large and
heavy enough, they fall to the ground as rain.
[4]
(b) Fig. 2B (INSERT) shows some facts about global warming.
With reference to Fig.2B, explain two negative impacts that global warming will
have on human settlements along the coasts.
Negative impacts in Fig.2B:
- Sea Level rise
o As a result of global warming, glaciers melt and introduce
more water to the ocean system,
o coupled with the higher temperatures in the atmosphere
causing water in seas and oceans to expand, thus resulting
in an increase in sea level.
o As mentioned in Fig.2B, the occurrence of climate change
has resulted in the Coral Triangle experiencing an increase
in sea level of 30-60cm by 2100, this might result in coastal
settlements being submerged under the sea.
- Low productivity
- Increased occurrence of extreme weather events i.e. typhoons and
cyclones.
- Acidified Oceans

- Effective building design can reduce the collapse of buildings and
minimise damage caused by an earthquake
o Steel and reinforced concrete
o Damping devices
o Construction of buildings with wide and heavy bases
o Base isolation bearings

14. Section B
3. (a) Fig.3A (INSERT) shows a map illustrating the global distribution of malnutrition.
(i) Describe the global distribution of malnutrition as shown in Fig.3A.
- Acute malnutrition are generally found in LDCs such as
South America and Africa, while absent in DCs such as
North America and Europe.
- The highest concentration of countries with acute
malnutrition population are found in the continent of Africa,
ranging to as high as >20% in Burkina Faso.
- India and Sudan also experiences a high proportion of
population with acute malnutrition (11-15%).
- Though having population facing acute malnutrition, it
constitutes a much lower percentage of 0-5% in countries
such as Brazil, Russa, Peru, and Thailand.
[3]
(ii) Explain two possible reasons for the distribution.
- Low Disposable Income
- Pricing of food
- Lack of stability of food supply due to civil war/natural
disasters
- Rapid population growth
[4]
(iii) With reference to Fig.3B and studies you have made, explain the
economic impacts a country with a high malnourished population will
face. Support your answers with examples.
Fig.3B:
[5]
[Turn Over 14
15. - When the population is malnourished, they will have lower
resistance to diseases and thus are weak and will fall sick
more easily.
- When they fall sick, they will not be able to turn up to work or
be less efficient while working, thus this will result in lower
productivity, such as producing less food. With less food
produced, there will not be enough to feed the family and the
whole vicious cycle will repeat itself.
- An example is in countries such as Sierra Leone, India, Sri
Lanka and Ethiopia, where low levels of nutrition intake have
resulted in farmers being less innovative and unable to
implement improvement to increase crop yield.
Higher public health expenditure:
- With more people falling sick, there will be an increase in
demand for health services, which would in turn increase the
overall costs of providing health care, putting a strain on the
country’s budget.
- For many LDCs, the higher spending on health care means
that limited financial resources are diverted from other areas
such as education, which would further slowdown the
country’s economic development and growth.
Long-term debt:
- Food aid and financial aid can be given to help people and
countries cope with insufficient supply of food, however, due
to the terms and conditions, this may result in the countries
being faced with long-term debt problems.
- For example, of the food and financial aid provided by the
USA, most of it requires the recipient to buy from USA’s
suppliers and transporters, thus ultimately indebting the
recipient to USA.
(b) Table 3C (INSERT) shows the amount of rice committed by each country to the
ASEAN Plus Three Emergency Rice Reserves (APTERR).
Explain how regional food policies, such as that seen in Table 3C, can help to
address food shortages.
- Regional food policies are decisions made by a group of
countries to ensure food security, such that in times of
emergency, food will still be able to be supplied.
- In Table 3C, the ASEAN Plus Three Emergency Rice Reserves
(APTERR), countries in ASEAN, together with China, Japan and
South Korea pledge to ensure food security for its members.
- This agreement requires the big rice producers and each member
country to supply rice for a reserve.
- For example, Brunei – 3,000tonnes, Philippines – 12,000, People’s
Republic of China – 300,000tonnes, and Thailand – 15,000tonnes.
[5]
[Turn Over 15
16. - This reserve will then be used to provide rice to countries, who
have signed the agreement, in times of disaster.
(d) “Social factors such as rapid population growth pose the greatest challenge to
overcoming food shortage.” To what extent do you agree? Explain your
answer.
Possible Content:
Agree because
- Social
o Rapid population growth
o Lack of accessibility
o Inadequate logistics of food distribution and storage
Disagree because

o Increased demand from emerging economies
o Food policies
o Soaring cost of fertilisers and transport

17. 4. (a) Fig.4A (INSERT) shows a map illustrating the adoption of Genetically Modified
(GM) crops around the world in 2006.
(i) Describe the variation in the adoption of GM crops around the world.
- The adoption of GM crops around the world varied greatly
from close to zero to almost half of the total crop land.
- It is most extensively adopted in the Paraguay, accounting
for almost 50% of the total crop land.
- It is least adopted in Australia, where the proportion is less
than 1%.
[3]
(ii) Explain how health and environment concerns might have resulted in
resistance in some farmers refusing to adopt GM crops.
Health concerns:
- Potential health risks
o There is a growing concern that incorporating foreign
genes into plants may have adverse effect on human
health, such as allergic reactions.
o For instance, a person who is allergic to lectin may
unknowingly consume it in a GM crop such as soy beans
and yet he is not aware of it due to the GM food not been
labelled.
Environmental concerns:
- Genetic pollution resulting in loss of biodiversity
o The process of genetic modification disrupts the
biochemistry of the plant and may produce new toxins,
allergens and anti-nutrients. This means that GM crops
have the potential to harm other organisms.
o An example of a species negatively affected by GM food
is the monarch butterfly, which feeds on milkweed. It has
been found that nearly half of the monarch butterfly
caterpillars died after eating mildewed dusted with pollen
B+ corn
- Development of superweeds
o Due to the transference of GM crop’s resistance to
herbicides
o This will cause loss of natural species and may result in
farmers using more potent and lethal
herbicides/pesticides in greater quantities, thus causing
more damage to the environment, implicating the non-
harmful species as well.
[4]
[Turn Over 17
18. (b) Photograph 4B (INSERT) shows a problem arising from of over-use of fertilisers.
Identify and explain how this consequence can have negative impact on the
marine life.
- The overuse of fertilisers cause them to be concentrated in the
soil and overtime, seep into groundwater or during rainfall, be
washed into streams and rivers by surface runoff.
- The fertilizer then become nutrients for algae to grow on the
surface of the water, resulting in eutrophication, which is the
presence of excess nutrients in water, leading to algae bloom.
- The algae bloom will deplete the oxygen in the water and block off
sunlight from reaching the aquatic plants, resulting in the death of
these plants.
- Without the sunlight, aquatic plants will not be able to
photosynthesis to replenish the oxygen level in the water,
resulting in a build-up of carbon dioxide.
- As the aquatic plants and algae decompose, they further use up
the oxygen in the water.
- Eventually the oxygen level in the water becomes depleted and
leading to the death of marine life.
[5]
(c) Fig.4C shows an article posted on aidsmap, an AIDS awareness website, about
reasons on non-disclosure of HIV-positive individuals.
Using information from Fig.4C and studies you have made, explain why it is
difficult to manage the spread of HIV/AIDS.
Fig.4C:
- Social Stigma
o HIV/AIDS patients may face various forms of discrimination,
which may lead to reused access to health care facilities,
rejection by family or community, and being expelled from
school or denial from housing.
o Thus, due to these prejudices, people who are HIV/AIDS
positive may be reluctant to disclose their status, resulting
in the virus being spread further.
Other Studies made:
- Difficulties in HIV detection
o As there are no visible signs of the disease for most of the
period of infection, infected people may continue with their
normal behavior without realizing they are infected.
o For example, in Congo, only 35.2 % of women with HIV
knew they had HIV before the test.
