Q

Explain how volcanic activity and orbital changes can cause climate change. (4 marks)

A
  • Volcanic ash can block out the Sun
  • This reduces temperatures on Earth. This tends to be a short-term impact
  • The Earth’s tilt affects the seasons so a greater tilt would extend seasons, a lesser tilt would shorten them
  • This also means that some regions of the world experience very long days and very long nights

Q

Explain how planting trees and using renewable energy can mitigate climate change. (4 marks)

A
  • Trees remove CO2 by photosynthesis
  • Release moisture into the air (cooling effect+reduces solar radiation)
  • Renewable energy sources do not emit CO2 (absorbs heat)
  • eg. Hydro-electricity and nuclear energy

Q

Explain the formation of a tropical storm. (4 marks)

A

Sun sends incoming solar radiation to Earth which warms our oceans to 27°C

This causes warm air to rise. This gives low pressure at the centre of the storm

This air cools as it rises causing condensation to occur, clouds to form and rain to occur

Some cooled air sinks back down helping to create the eye

Air rushes in from higher pressure areas outside of the storm to lower pressure areas at the centre of the storm creating winds

The whole storm rotates because of the Earth’s spin (Coriolis effect)

Q

Explain how the effects of tectonic hazards vary between areas of contrasting wealth. (6 marks)

A

Effects in LIC countries are more profound

  • Nepal (2015) 9000 people died and 3 million left homeless
  • This is due to them not having enough money to prepare like building better buildings etc

Effects in HIC countries are less extreme

  • Christchurch (2011) earthquake 481 died
  • They have better prediction equipment due to them having more money

Q

Explain how plate boundaries can cause tectonic hazards. (6 marks)

A

Destructive plate margin

  • Between oceanic and continental when moving towards each other(eg Nazca plate and South American)
  • When the more dense oceanic crust subducts the continental crust, it creates strong earthquakes.
  • Can also form steep sided volcanoes

Conservative margin

  • Two plates are moving past each other
  • eg San Andreas Fault and Pacific plate
  • Earthquakes happen as stresses gradually build up over many years
  • These are released when plates suddenly slip and shift

Q

Explain how we can mitigate and adapt to climate change. (6 marks)

A

Carbon capture and storage

  • Carbon gas is captured and compressed
  • Transported by pipeline to an inject well to be stored in suitable geological reservoirs

Alternative energy sources
-Hydro-electricity, nuclear power, solar, wind and tidal power

Planting trees

  • Trees act as carbon sinks, removing CO2 from the atmosphere by photosynthesis
  • Moisture released has cooling effect

Q

Choose either an earthquake or a volcanic eruption. Assess the extent to which primary effects are more significant than secondary effects. Use an example that you have studied. (9 marks)

A

Nepal

  • primary: 9000 died and 20,000 injured
  • secondary: avalanche killed 19
  • 1.4 million people needed food, water and shelter
  • Landslide were triggered, slowing down relief efforts
  • hospitals were overwhelmed
  • avalanche left 250 missing

Q

Assess the extent that prediction is the most important factor in reducing the effects of tropical storms. (9 marks)

A

Yes

  • National hurricane centre in Miami in North Atlantic
  • hurricane watch/hurricane warning
  • can be used to warn people to get into shelter

No

  • Protection
  • For example, in Bangladesh 2000 cyclone shelters have been built
  • Strong concrete and built on stilts in case of floods
  • Place where people can go to when a storm in predicted

No

  • Planning
  • USA-National Hurricane Preparedness week.
  • Make action plans and educating about dangers
  • Raises awareness and people then know what to do in the event of a tropical storm

Q

Explain how eco-tourism helps manage the rainforest sustainably. (4 marks)

A

Ecotourism allows tourists a safe and sustainable way to explore the rainforest

For example, tourist leaders can guide the along paths that have already been made to ensure the rainforest itself does not get damaged

Economic advantages
Tourists spend money
This money is spent to by the government and the local community to sustainably manage the rainforest

Q

Explain the role of producers in an ecosystem. (4 marks)

A

Producers convert energy from the environment (mainly sunlight) into sugars (glucose)

The most obvious producers are plants that convert energy from the sun by photosynthesis

30
Q

Assess the physical and human causes of flooding. (6 marks)

A

Physical

  • Precipitation can lead to sudden flash floods as river channels cannot contain all the water
  • Geology (rock type) impermeable rocks like shales and clays cause surface run off
  • Steep slopes

Human

  • Urbanisation-Tarmac roads, concrete driveways and slate roofs. Makes flooding more likely
  • Deforestation-No infiltration and temporary storage. More surface run off
