Natural hazards
Give an example of a tectonic hazard
volcanic eruption, earthquake or tsunami
What are the 4 layers of the earths structure
inner core, outer core, mantle, crust
What category of hazard is a tropical storm? (hydrological, atmospheric, geological/tectonic or biological)
Atmospheric
What is climate change?
The change in the average temperature and precipitation of a place.
Define a natural hazard
A natural event which has negative impacts on people or their lives
constructive, destructive and conservative
What is your atmospheric hazard case study?
'Super' Typhoon Haiyan
Give one natural cause of climate change
Volcanic activity
Orbital changes
Sunspots
Which type of plate boundary has the most explosive volcanic eruptions? Why?
Destructive because there is a large build up of pressure
What are your two geological/tectonic hazard case studies?
Chile and Nepal
What is your hydrological hazard case study?
Somerset levels
Give an example of how we can mitigate (reduce) climate change
renewable energy (solar, wind, hydro)
public transport
buy local
eat less meat
stop deforestation
Which place has a higher hazard risk to a tectonic hazard?
a. California
b. Rugeley
a. California as it is on a conservative plate boundary called the San Adreas fault
Describe the distribution of earthquakes and volcanoes (3 marks)
Earthquakes mainly found on plate boundaries
Volcanoes mainly found on plate boundaries
Some volcanoes are found in the middle of plates
What are the three types of cell on the GAC model. In the correct order from the equator towards the North pole.
Hadley, Ferrel, Polar
What is the difference between mitigating climate change and adapting to it?
Mitigation - trying to stop climate change from happening
Adaptation - adapting to live with the changes
What are the 4 categories of natural hazards?
Hydrological, biological, geological/tectonic, atmospheric
Why did Chile have a lower death rate of 500 compared to Nepal's 6000. 2 reasons needed
- more money
- more money helps with the 3P's
- nepal was in mountains so had avalanches
- nepal is LIC so had lesson money
- nepal therefore didn't have money for 3P's
Give 2 of the 3 things needed for tropical storms to form
ocean temps 27 degrees Celsius and above
low air pressure
between 5 and 15 degrees north and south of the equator
open ocean
Burning fossil fuels releases greenhouse gases (CO2) which traps the suns rays into our atmosphere increasing global temperatures
