	Earthquake	Volcanic eruption
MEDC (MIC)

f.      Important notes: such as …

                                          i.    Why is the event important?

                                         ii.    How did this event help future prediction?

                                        iii.    What could be done to minimise the impact of a similar event in the future?

      2.     Give an example of a place in the world where there is …  

a.     A destructive margin

b.     A constructive margin

c.     A conservative margin

d.     A collision zone

      3.     Name three positive impacts of volcanic eruptions for the people who live nearby?

      4.     What piece of equipment measures the strength of an earthquake?

      5.     What is the difference between the quake’s focus and its epicentre?

      6.     What scale do we measure earthquakes on?

      7.     For an earthquake that you have studied …

a.     Name where and when it occurred.

b.     Why did it occur?

c.     What were the primary effects?

d.     What were the secondary effects?

e.     What did people do to minimise the effects of future quakes?

      8.     What is a tsunami?

      9.     Why do earthquakes and volcanic eruptions seem to cause more damage in LEDCs than MEDCs?

Revising Settlements

As promised here is a little revision for those who wish to keep their little grey cells ticking over during the break.

Read the Settlement Notes

Here are some questions to help you.

1. What is a settlement?

2. Write out the following settlement types in order of size (smallest to largest).
City, village, town, hamlet, conurbation

3. List five factors that will affect where a new settlement is built? (Think ancient times)

4. What is the difference between a settlement’s site and situation?

5. What is meant by a settlement’s function?

6. What is the function of the following settlements …

a. Dover

b. Chamonix

c. Sheffield (c1900)

7. For each of the following three village shapes, draw a diagram to show what it looks like and offer a suggestion as to why it might have occurred …

a. Nucleated

b. Linear

c. Dispersed

8. What is meant by the words …

a. Urbanisation

b. Suburbanisation

c. Counterurbanisation

9. What is a service?

a. Give three examples services that you would expect to find in a city?

b. Give three examples services that you would expect to find in a village?

10. Draw a clearly labeled diagram of the Burgess Model of land-use.

a. What do the letters CBD and ZIT stand for?

b. What would you expect to see if you visited each of these zones?

c. What are the weaknesses of Burgess’ model? (compare the model to real life).

11. What sorts of problems are often associated with the Inner City or ZIT?

12. What can governments do to improve the ZIT? (give an example of where this has happened)

Extension:

Watch the Megacities Video and think about .

Why do people move to the cities? (Think PUSH and PULL factors and OBSTACLES)
What are the logistical and social problems created by having so many people living so close together?

Is it Imogen's fault?

 

Is it not a coincidence that since the Met Office started naming our storms we have already got as far as 'I' for Imogen? Did they know what was coming our way when they started to give them names?

Click here to see the BBC Weather forecast for Imogen.

Imogen is the latest depression to batter the UK and this time it is us is the Southeast who will feel her rage with wind speeds of up to 90mph along the south coast. Current wind speeds here at Brambletye are around 30-40kph with gusts exceeding 70kph: see our data on the Weather Underground site.

Why are we getting so much 'bad' weather in the UK this year? It seems to have been a catalogue of floods, storms and hurricane force winds: weather records are being broken every year.

As BBC weatherman, John Hammond, explained in Countryfile yesterday (See the episode on iPlayer - first 15 minutes) , the repeated extreme weather, and flooding in places such as Cockermouth, is a side effect of this being an 'el nino'. This is a major el nino year and the warm ocean currents in the Pacific Ocean have altered weather patterns globally just as was predicted back in May. We are getting high winds and floods; the US has had extreme snow storms (the so-called #snowmaggedon2016 and tornadoes and Sub-Saharan Africa is experiencing the worst drought in years! Zimbabwe has declared a state of emergency as farmers are losing up to 80% of their livestock due to the drought (read the story).

I wonder if this chap has started to believe in Climate Change? (he didn't in September 2015)
