answer this

any two from: two parts, inner and outer; outer is liquid, inner is solid; outer core is thicker (2200 km) than inner core (1250 km); radius of core is 3450 k

10

The average radius of the Earth is 6400 km. Use the information on the diagram to calculate the approximate thickness of the Earth’s crust.

(6400 – (1250 + 2200 + 2900) =) 50 (km);

5

Name the three main types of rock found in the Earth’s crust.

igneous AND sedimentary AND metamorphic;

5

Explain how heat in the Earth’s crust can be used to generate electricity in a geothermal power station

any three from: cold water is pumped underground; contact with hot rocks heats the water; water is changed to steam; steam is piped to, (geothermal) power sta

15

Geothermal energy can be one benefit of living near a volcano. Suggest other benefits of living near a volcano.

any three from: lava / ash (weather to produce) fertile soils for farming; tourism (scenery is tourist attraction); e.g. health spas / volcanic scenery / hot s

15

Name the two continents where there has been no change in the number of megacities between 2005 and 2015.

North America AND Oceania;

10

Calculate the percentage increase in megacities in Asia between 2005 and 2015. Show your working.

(10 / 11 x 100 =) 90.9 / 91;;

10

The populations of megacities are growing faster in developing countries than in developed countries as a result of push and pull factors. Explain what is meant by the terms push factor and pull factor.

push factor: negative factors / reasons, that make people want / force them to leave, an area; pull factor: positive factors / reasons, that attract people to

10

Describe two environmental problems caused by rapid population growth in cities.

pressure on land causes, deforestation / loss of habitats; loss of, agricultural land / green spaces / green belts; air pollution / smog, from traffic / indust

10

Name the country responsible for almost one quarter of global greenhouse gas emissions in 2012.

China

5

Name the developed country responsible for the largest percentage of global greenhouse gas emissions in 2012.

USA

5

Calculate the total percentage of greenhouse gas emissions from the developing countries that are named in the pie graph.

(24.0 + 6.0 + 6.0 + 1.5 + 1.5 =) 39(%);

5

Suggest disadvantages of solar power as a source of energy. (3)

any three from: not reliable / inefficient; energy only produced in daylight hours / no power generated at night; power may not be generated when, the sky is c
