Energy is constantly being recycled around the Earth. Most of this energy comes from the Sun.
Which of these renewable energy resources does NOT supply energy that originates from the Sun?
Solar
Biomass
Wind
Geothermal
What is the purpose of the facility shown in the picture?
To provide a source of renewable energy.
To measure the levels of carbon dixoide in the atmosphere.
To reduce the amount of carbon dixoide emitted by power stations.
To take carbon dioxide out of the atmosphere.
Agriculture is a major contributor to greenhouse gas emission.
Which of these agricultural sources gives off much less greenhouse gas than the other three?
Carbon dioxide given off from running farm machinery.
Carbon dioxide from converting land to grow crops.
Nitrous oxide from using fertilisers in the soil.
Methane given off by cattle.
Carbon dioxide is naturally removed from the atmosphere in various ways.
Which of the following makes a much smaller contribution to removing carbon dioxide than the other three?
Some is absorbed by the oceans.
Some is absorbed by plants during photosynthesis.
Some escapes into space.
Some is absorbed by the soil.
What kind of renewable power station is shown in the picture?
Biomass
Geothermal
Hydroelectric
Solar
Which of these is NOT an alternative energy source for cars?
Nitrogen
Hydrogen
Biodiesel
Electricity
Which is the correct statement about biofuels?
Biofuel plants release a small amount of carbon dioxide while growing.
Biofuel plants capture carbon dioxide while growing and then release it when they are burned, making them carbon-neutral.
Biofuel plants capture carbon dioxide while growing, but no carbon dioxide is released when they are burned.
Biofuel plants release more carbon dioxide per tonne into the atmosphere than fossil fuels.
Which statement gives the correct link between melting ice caps and global warming?
As polar ice caps melt...
... the oceans heat up, leading to increased global warming.
... the rise in fresh water in the oceans leads to an increase in global warming.
... less sunlight is reflected back into space, leading to increased global warming.
... large amounts of carbon dioxide are released, leading to increased global warming.
The graph shows the famous Keeling curve, which tracks the rise in atmospheric carbon dioxide since the 1960s.
The zig-zag shape is due to the fact that the amount of carbon dioxide measured goes up and then down each year. Why does this happen?
The distance of the Earth from the Sun affects the amount of carbon dioxide in the atmosphere.
People use their heating more in winter, which emits more carbon dioxide.
The curve matches the seasons in the Northern hemisphere, where most of the Earth's land-based plants are found.
The oceans heat up during the summer, releasing carbon dioxide into the atmosphere.
A temperature of more than 1400 degrees Celsius is needed to produce this material, a process that consumes vast quantities of fossil fuel.
The carbon dioxide emissions from producing this material are very high. If it were a country, it would be the third-largest emitter of CO2 after China and the United States.
What is the material?
Concrete
Rubber
Steel
Copper
