Total questions: 30
Worksheet time: 15mins
The Earth’s early atmosphere was mainly due to:
Waterfalls
Volcanic activity
Meteors
Earthquakes
Select the true statements from the list below.
The early atmosphere probably contained little or no oxygen.
The early atmosphere contained a high proportion of oxygen.
The early atmosphere probably contained a large amount of carbon dioxide.
The early atmosphere probably contained a small amount of carbon dioxide.
What is the proportion of nitrogen in the modern atmosphere?
21%
0.04%
78%
0.9%
As the Earth cooled, water vapour condensed to form the oceans.
True
False
The amount of carbon dioxide in the atmosphere decreased due to ...
... it forming carbon dioxide
... it becoming carbonate in rocks.
... it dissolving in the oceans.
... it splitting up into carbon and oxygen.
Select the correct equation for photosynthesis.
C6H12O6 → 2C3H6O3
C6H12O6 +6O2 → 6CO2 +6H2O
C6H12O6 → 6CO2 + 6H2O
C6H12O6 +O2 → C3H6O3 +3H2O +3CO2
Photosynthesis changed the atmosphere as:
It increased the concentration of carbon dioxide in the atmosphere.
It decreased the concentration of carbon dioxide in the atmosphere.
It increased the concentration of oxygen in the atmosphere.
It decreased the concentration of oxygen in the atmosphere.
What is the test for oxygen?
Hold splint to test tube.
Hold glowing splint to test tube and see if it relights.
Hold lit splint to test tube and see if there is a squeaky pop.
Hold lit splint to test tube and see if it goes out.
Select the greenhouse gases from the list below.
Methane
Carbon dioxide
Oxygen
Water vapour
Which of these effects on the planet is not associated with burning fossil fuels?
Global warming
An increase in the amount of oxygen in the oceans.
An increase in the amount of carbon dioxide in the atmosphere.
Which of these gases make up the smallest proportion of our atmosphere?
Oxygen
Nitrogen
Carbon dioxide
True or false? “The Earth’s crust and the oceans are the only sources of minerals and other resources that humans need.”
True
False
True or false? “Limestone is formed from the shells and skeletons of marine organisms which have been buried under layers of sediment.”
True
False
True or false? “Scientists think that the early atmosphere contained more carbon dioxide than oxygen”.
True
False
What caused the proportion of oxygen in the air to increase as the atmosphere evolved?
Burning fossil fuels
Volcanic eruptions
Plants and algae photosynthesising.
True or false? “Plastic bags can be made with polymers and cornstarch to make them last forever.”
True
False
What process can be used to separate out the different gases in air?
Climate change
Cracking
Fractional distillation
As the atmosphere evolved, the amount of carbon dioxide decreased due to:
Absorption by oceans
Formation of carbon precipitates on the seabed, which later formed sedimentary rocks
Photosynthesis by plants and algae
Respiration by plants and algae
The ozone layer is important because it:
Contains oxygen
Allows respiration to occur
Blocks harmful rays from the Sun
Allows photosynthesis to occur
The greenhouse effect is:
Bad.
Responsible for keeping our climate temperate.
When short-wavelength radiation is absorbed and re-emitted from the Earth’s surface as long-wavelength radiation which is absorbed by greenhouse gases in the atmosphere which then re-radiate it in all directions.
Something that allows crops to grow.
Global warming is caused by:
The enhanced greenhouse effect.
Increasing levels of carbon dioxide in the atmosphere.
Increased energy consumption.
Decreased global population.
Deforestation is a problem as it results in:
Less carbon dioxide being produced.
Less carbon dioxide being taken in.
Less oxygen being produced.
Less oxygen being taken in.
Methane is increasing in the atmosphere due to:
Photosynthesis
Respiration
Combustion
Release from paddy fields
Ice caps melting due to global warming is problematic as it could lead to:
Increased flooding.
Poor boat sales.
Deforestation.
Population explosion.
How do scientists predict how the climate might change?
Looking at the sky.
Making bonfires.
Using computer modelling.
Most scientists agree global warming is anthropogenic.
True
False
Why is historical climate data less accurate than modern data?
Less data exists.
Data taken over fewer locations.
Methods used to take data were less accurate.
Data was made up by climate change sceptics.
We can estimate past climate change data by:
Asking elderly relatives.
Analysing fossils.
Analysing tree rings.
Analysing gas bubbles trapped in ice sheets.
We can reduce our carbon dioxide emissions by:
Driving whenever possible
Walking shorter distances instead of driving
Turning down our central heating
Washing bed linen and towels daily.
We could be more energy efficient as a country by:
Cutting down local woodland.
Using more renewable resources.
Stopping car sharing schemes.
Using lot fires to heat our homes.
