Geography Edexcel B Dynamic Planet Unit 2 REVISION CARDS

Climate and Change Revision Cards 

If you want to print them, you'll have to fold each card where the blue line in the middle is and glue it down. You can then use it to test yourself on the questions. I recommend going through the cards once before you revise and put the cards into two piles; Know, and Need to revise. Then go through and learn the cards in the Need to revise pile. 

Exams are so soon and I need all the good karma I can get! I hope these are as useful for you as they were to me. Good luck! :)

insects living space
·More air conditioning · Heat waves death and illness in

Alexandria will be underwater

Give 4 examples of
greenhouse gases, where
Name some human activities
they come from and what
which contribute to the
percentage it is out of all
enhanced greenhouse effect
the greenhouse gases
Carbon dioxide:
· Burning fossil fuels, deforestation by burning
down forest
·Driving · 89%
·Burning fossil fuels Methane:
·Eating meat cattle ranches · Gas pipeline leaks, farming rice in paddy
·Rice farming fields, cattle farming
· 7%
Nitrous Oxide:
· Jet aircraft engines, cars, lorries, fertilisers
and sewage farms
· 3%
Halo carbons:
· Industry, solvents, cooking equipment
· 1%
Name the 5 air masses What will the UK's

1. Arctic: air masses from the arctic bring very
strong cold wind and snow
·Overall UK summers will be warmer and

Continental Europe bring dry, hot weather in the ·By 2080 temperatures will have risen by
