Provide two reasons why it is hotter at the equator
atmosphere is thicker at the equator
The angle of the sun’s rays mean the heat is more intense at the equator
atmosphere is thinner at the equator
When warm air rises, what kind of pressure does this create?
low pressure
high pressure
Warm air rises, creating low pressure... but what kind of weather does this create?
settled - low rainfall
unsettled - high rainfall
Name the three global circulation cells
Hadley
Ferrell
Solar
Polar
What is the role of the global circulation cells?
to circulate / redistribute heat
help the world to spin
Warm water also rises, while cold water sinks. These are called ocean currents - what are their role?
to redistribute heat within the oceans
help the world to spin
What is the band of low pressure known as on the equator?
low pressure zone
ITCZ
Low pressure at the equator (ITCZ) causes what kind of weather?
settled - low rainfall
unsettled - high rainfall
PAST CLIMATE CHANGE - Do volcanic eruptions make our climate hotter or colder?
hotter
colder

makes our climate colder
makes our climate warmer

less extreme
more extreme
Trees rings are evidence for past climate change. Each ring represents what?
a week's growth
a day's growth
a year's growth
If the tree rings are further apart (the tree has grown more), this shows that the past climate was... ?
colder, drier
warmer and wetter
Fossils can also be used as evidence for past climate change - they can tell us the UK used to be warmer. For example, 120,000 years ago, which animals roamed what is now London?
ducks and swans
pigs and sheep
pugs and collies
rhinoceroses and elephants
Ice cores can be used as evidence for past climate change. Which gas is trapped in the ice and can be measured to tell us the climate in the past?
nitrogen
oxygen
Co2
methane
What does this U-shaped valley tell us about the climate in this area in the past?
it was warmer
it was colder
What is a problem of using historical paintings as evidence for past climate change?
the paintings might not be very good
the paintings were not meant to be used as evidence so might not be accurate
The Natural Greenhouse Effect - What type of radiation comes from the Sun?
Longwave radiation
Shortwave radiation
The Natural Greenhouse Effect - Earth converts the shortwave radiation to long wave heat energy and absorbs what percentage?
10%
12%
100%
50%
However, as the layer of greenhouse gases is getting thicker, more heat is getting trapped and average temperatures are ... ?
decreasing
increasing
Why are we producing MORE greenhouses gases than ever before? (SELECT TWO)
the global population is decreasing
the global population is becoming more affluent / richer
the global population is increasing
the global population is becoming poorer
As humans, how do we produce carbon dioxide? (SELECT TWO)
breeding cows
using technology such as ipads, phones, TVs
landfill sites
driving cars / lorries
How do we produce methane?
driving cars / lorries
breeding cows for red meat
throwing rubbish into landfill sites
using technology such as phones and ipads
Apart from landfill and cows, which crop also produces methane?
wheat
barley
rice / paddy fields
What percentage of China's energy comes from coal?
10%
100%
70-75%
2%
Methane is actually how many times more potent (stronger) than carbon dioxide?
100, 000
20
What problems might be caused as a result of climate change? (SELECT THREE)
sea levels decreasing
sea levels rising / melting sea ice
droughts
more extreme weather events e.g storms and hurricanes
The ten hottest years on record have occurred since 1998, with 2005, 2010 and 2014 as the hottest.
True
False
Countries closer to where are likely to suffer the most from droughts and decreasing crop yields?
the poles
the equator
Which countries will be affected by climate change the most?
Developed (rich)
Developing (poor)
Research has shown that what % of the glaciers in Antarctica are retreating?
1%
90%
2%
12%
Why is it so difficult to accurately predict future changes in temperature and sea level? (SELECT TWO)
We know for certain what will happen in the future
What the world’s future population will be
Whether fossil fuels will continue to be used, or whether there will be a shift to cleaner energies such as wind or solar.
Why might climate change cause food prices to increase?
There will be MORE droughts so we will be able to grow MORE food = food prices increase
There will be MORE droughts so we will be able to grow LESS food = food prices increase
