1

The early atmosphere was formed by green plants and algae producing oxygen.

Select one of the following:

True
False

Explanation

Question 2 of 11

1

Select the four TRUE statements.

Select one or more of the following:

Condensation of water from the Earth’s atmosphere formed the oceans.
Carbon dioxide dissolved into the sea, reacting to form sediment on the sea bed.
The shells and skeletons of marine life contained carbonates from the ocean.
Crude oil is formed from compressed deposits of plankton.
Most of carbon dioxide from the early atmosphere was taken back in by volcanic pressure.
Limestone is mostly made of calcium trioxide deposits from the bones of dinosaurs and mammals.
Coal is made from the collection of carbon sediment form the sea bed, originally formed when carbon dioxide dissolved into the sea.

Explanation

Question 3 of 11

1

Select the main greenhouse gases.

Select one or more of the following:

Carbon dioxide
Water
Methane
Oxygen
Hydrogen
Nitrogen

Explanation

Question 4 of 11

1

Increasing levels of carbon dioxide have been linked to climate change

Select one of the following:

True
False

Explanation

Question 5 of 11

1

What is the main reason it's so hard to fully understand the Earth’s climate?

Select one of the following:

There are too many variables
We don’t understand particle physics well enough
Things have been oversimplified
Al Gore

Explanation

Question 6 of 11

1

Select the main FOUR effects of climate change

Select one or more of the following:

increased temperatures will cause survival stress on humans and wildlife
less water availability will cause stress as fresh water supplies will diminish
decrease in food production of some regions will cause food shortages
changes to wildlife distribution, and migration patterns
increase in sulphur in the atmosphere, may make some areas uninhabitable
tornadoes in countries, like the UK

Explanation

Question 7 of 11

1

Select six sensible ways to reduce carbon footprints

Select one or more of the following:

use more alternative energy supplies
reduce your energy consumption, and efficiency, in your home
reduce your use of cars, or increase the fuel efficiency
store carbon emissions deep underground, in areas such as old oil wells
tax greenhouse gas emissions
recycle more
use industrial air conditioners to cool down the Earth
leave the Paris Climate Agreement
kill all the animals we breed for food

Explanation

Question 8 of 11

1

The carbon footprint can be reduced by reducing emissions of carbon dioxide and methane. Here are some of the ways that governments can reduce our carbon footprint:
capture, and store, carbon - ❌ from power stations can be stored underground
increase/introduce taxes - penalise companies/individuals for releasing too many ❌
carbon off-setting - plant more trees (❌) to convert ❌ into ❌
carbon neutrality - companies introduce methods, such as ❌, to take out as much carbon dioxide as they put into the atmosphere. Overall the amount of ❌ entering the atmosphere would be zero

Select from the dropdown lists to complete the text.

( carbon monoxide, carbon particulates, sulfur dioxide, nitrogen oxide, carbon dioxide ) is a toxic, colourless and odourless gas, and it preferentially (and permanently) binds to haemoglobin in red blood cells instead of oxygen

( carbon particulates, carbon monoxide, carbon dioxide ) are unreacted carbon atoms that cause soot that can damage/clog up appliances, contributes to smog and global dimming

( sulfur dioxide, nitrogen oxide, carbon monoxide ) is caused by sulfur impurities in fossil fuels like coal and crude oil can react with oxygen when the fuels are burned

( sulfur dioxide, carbon dioxide, carbon monoxide, carbon particulates ) can dissolve in rain water to produce acid rain, which can damage structures, and wildlife habitats such as lakes and forests

( nitrogen oxides, carbon oxides, sulfur oxides ) form when when fuels are burned in engines, oxygen and nitrogen from the air can react together at high temperatures to produce oxides of nitrogen, these can also dissolve in rain water to produce acid rain
