Q

Health issues of an ageing population?

A
  • busy health services dealing with elderly health issues, costs a lot of money and time to deal with this

Q

Why are the people of Naples vulnerable to pyroclastic flows?

A
  • Really close in prox. to the volcano
  • Dense pop. so slow evac. times
  • It is between 2 mountains, the valley would channel the flow into them
  • They are located on the coast so they can only travel North
  • Not a high earning country so emergency services aren’t the best available, though they can’t do much in the time of the quick speed of a p.flow anyway.

Q

How are shield volcanoes formed?

A

Lava finds its way to the surface through cracks.Magma produces fluid lava, travelling long distances before solidifying. Frequent eruptions form the mountains.

17
Q

Composition of a shield volcano?

A

Lava with no layers

18
Q

Example of a shield volcano?

A

Mauna Loa, Hawaii

19
Q

Where are stratovolcanoes most likely to form?

A

Destructive plate margins

20
Q

Lava type of a stratovolcano?

A

Acidic, viscous and sticky

21
Q

What is the shape of a stratovolcano?

A

Conical + steepsided

22
Q

How are stratovolcanoes formed?

A

Lava is acid, has high viscousity and cools quickly. Eruptions of ash and lava forms a cone shaped volcano with steep sides as the lava does not flow far before solidifying.

23
Q

What is the composition of a stratovolcano?

A

Alternative layers (derived from the word ‘strata’) of ash and lava.

24
Q

Example of a stratovolcano?

A

Pinatubbo, Phillipines (erup. in 1991)

25
Q

What is the relationship between magnitude and frequency of volcanic eruptions?

A

The smaller the magnitude, the higher the frequency.

As magnitude increases, the frequency decreases.

26
Q

What type of scale does the Richter scale use to measure the magnitude?

A

A logarithmic scale, with each number on the scale ten times the magnitude of the one before it.

27
Q

Why is there more damage from natural disasters in LICs?

A
  • Weaker infrastructure, informal/poor quality housing
  • Poor education, people panic and make rash decisions
  • Poorly trained emergency services
  • Lack of money to rebuild
  • Lack of emergency/back up rations
28
Q

Why is there less damage from natural disaster in HIC’s?

A
  • Better quality of buildings, most being Earthquake proof
  • Proper planning and education, people know the correct procedures
  • Emergency services are trained to know what to do
  • More money to rebuild - alleviate the impact
29
Q

What social impacts do Earthquakes have?

A
  • Financial strain
  • Increased community spirit
  • Emotional/psycological impacts
  • Loss of businesses - unemployment
  • Homelessness
30
Q

What is the carbon cycle?

A

The movement of carbon between the atmosphere, land and the oceans.

31
Q

What are some examples of natural carbon stores?

A

Forests and oceans.

32
Q

Which processes help move carbon?

A

Photosynthesis - taken in by plants, animals eat the plants, animals eat other animals ect.
Respiration - C02 let out by all living organisms.

33
Q

List some ways in which could be evidence for climate change.

A

Tree rings, old agricultural notes and records, glaciers, migration of birds and other animals, the Keeling curve and met office weather patterns.

34
Q

How are ice cores used as evidence for climate change?

A
  • Gas from the atmosphere gets trapped within the layers of ice every year.
  • Scientists drill into the sheets and take them back to a lab to analyse.
  • If the concentrations of co2 are high, it means the planet was generally warmer, If the concentrations are low, it means the planet was generally cooler.
35
Q

How can volcanoes contribute to climate change?

A

Large eruption launches ash, dust and sulphur into the air.
Global circulation system moves the toxic gasses around.
Build up can lead to reflecting sunlight back into space.
Less solar energy reaches the Earth, leads to average temperatures cooling.

36
Q

Where do hurricanes usually form?

A

Between the tropic of cancer and the tropic of capricorn.

37
Q

Why are more intense hurricanes forming?

A

Increase in sea temperature which increases the air masses above it.
This means the air rises quickly and there are higher evaporation rates.
This leads to more water vapour and energy within the storms, leading to a greater intensity.

38
Q

Where are lines of longitude?

A

Vertical lines on maps

39
Q

Where are lines of latitude?

A

Horizontal lines on maps

40
Q

How is the path of a hurricane presented on a map?

A

Usually a solid red line, with dots and labels to inform us on the dates of travel.

41
Q

Environmental/economic effects of hurricane Matthew?

A

The hurricane resulted in flooding, landslides, and extensive destruction of infrastructure and livelihoods.

The agriculture and housing/urban sectors were the hardest hit, with up to 90 percent of crops and livestock lost in some areas.

Thousands of structures were damaged, and key roads and bridges were washed away.

42
Q

Social impacts of hurricane Matthew?

A

The disaster affected over 2 million people, about 20 percent of Haiti’s population, primarily in the poorest regions of the county.

It’s estimated that over 450,000 children were out of school.

A sharp increase in suspected cholera cases was recorded in affected departments.

The vaccine cold chain was destroyed, costing the health sector close to a million in losses.
