3 of 34
what is a collision plate?
when the two plates collide into each other
4 of 34
name two things that a shield volcano has?

5 of 34
name two things a composite volcano has?
found on destructive and do not erupt frequency.
6 of 34
primary impacts of an earthquake?
people sleeping in streets and people dying
7 of 34
secondary impacts of earthquake?
tsunamis and fires occur
8 of 34
how do to predict volcanoes and earthquakes?
see that bird and animals are moving and also gas emissions rising because it heats the earth
9 of 34
how can we not predict earthquakes?
how big the impact is and when it will erupt?
10 of 34
name a case study for an earthquake?
Haiti- 250,000 houses destroyed and people killed
11 of 34
the relief efforts of the earthquake?
shortage of clean water and lots of people still living in tents
12 of 34
for a named volcano explain the primary impacts?
the Montserrat volcano erupted in 1995 affected the whole of the capital city covered in ash.
13 of 34
what are some of the natural causes of climate change?
amount of energy radiated from the sun and ocean current changing become warmer and cooler
14 of 34
impacts of climate change.
cold winters and shorter summers, crops did not grow meaning less productivity.
15 of 34
present and future climate change?
levels of carbon dioxide increase
16 of 34
state two challenges for people in the uk because of climate change?
there could be a temperature and less predictable rainfall meaning there will be drier summers.
17 of 34
economic impacts of the climate change in the UK?
worse storms, ecosystem change meaning they could be affected.
18 of 34
what are the possible economic impacts of climate change?
when floods occur businesses close which means they loose money and also soil is affected which affects farming.
19 of 34
what are the 5 different biomes?
deciduous, coniferous, tundra, desert, tropical,
20 of 34
what does the life support system do?
it regulates water, keeps soil healthy, regulates gases making up the atmosphere

what are some of the threats to the biosphere?
Deforestation, mining, farming

name a management scheme for the biosphere?
wicken fen it aims to keep all the species a live and rare living organisms healthy?
23 of 34
for a named example where has unreliable water resources?
sahel has very dry seasons therefore the water needs to be stored.
24 of 34
named example of a water management system?
hoover dam on the Colorado river in the USA, stops flooding, generates electricity, stored water is used for growing cities such as Las Vegas.
25 of 34
what are the disadvantages of the hoover dam?
land is lost, less water for places like mexico
26 of 34
what are local ways of storing water?
wells dig to get underground water and are lined preventing sewage
27 of 34
how do waves erode the coastline?
hydraulic action- waves hitting rocks forming air pockets. abrasion when waves pick up stones. attrition-pebbles collide hitting cliffs
28 of 34
factors affecting coastlines?
erosion, rock type,fetch
29 of 34
coastal managing and hard engineering types?
sea wall, rip rap, groynes
30 of 34
reasons for coastal retreat?
holderness coastline, to stop erosion and increase tourism round the area
31 of 34
reasons for not protecting?
very expensive, local people are affected and also may not be sustainable.
32 of 34
what are the characteristics of the hot and arid regions?
very little rainfall , hot temperatures,
33 of 34
polar climate characteristics?
cold because of latitude, summers are short, cold glacial regions
