Which answer correctly describes the effect of a greenhouse gas on the Earth?
Greenhouse gases act like an insulating layer in the Earth's Atmosphere keeping the Earth warm enough to support life.
Greenhouse gases act like a reflecting layer in the Earth's Atmosphere returning the heat to the Earth.
Greenhouse gases act like a hot water bottle in the Earth's Atmosphere radiating heat around the Earth.
Greenhouse gases act like an cooling layer in the Earth's Atmosphere keeping the Earth cool.
Which of these processes is not an effect of the electromagnetic radiation, given out by the Sun, whent he radiation reaches the Earth's atmosphere?
passes through
absorbed
re-emitted
transferred

DEFORESTATION
BURNING FOSSIL FUELS
CATLE FARMING
ADDING WASTE INTO LANDFILLS
Only deforestation
Only burning fossil fuels
Deforestation and burning fossil fuels
All of them
Over the last 200 years the percentage of carbon dioxide has increased in the atmosphere. From the graph this correlates with...
...an increase in global temperature due to uncertain emissions
...an increase in global temperature due to increased use of fossil fuel
...a decrease in global temperature due to erroneous emissions
...a decrease in global temperature due to increased use of fossil fuels
Which of these is NOT a possible consequence of global warming?
Increased melting of the polar ice caps
Rise in sea levels
Changes in rainfall patterns
More frequent globalization
Why might it be difficult to predict climate change in the future?
Predications made by extrapolating data are not accurate
Predictions and models are not realistic.
Greenhouse gas emissions may change.
Models are oversimplified.
Climate change can have dangerous consequences, one of which is the frequency and severity of storms may ... , causing flooding on low lying land.

Increase in some regions ability to produce food.
Too much rainfall in some regions.
Decrease in some regions ability to produce food.
Too little rainfall in some regions.
We now realise climate change is due to human activity. What is the main cause of this human activity?
