Question 1

Question
The early atmosphere was formed by green plants and algae producing oxygen.
Answer
  • True
  • False

Question 2

Question
Select the four TRUE statements.
Answer
  • 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.

Question 3

Question
Select the main greenhouse gases.
Answer
  • Carbon dioxide
  • Water
  • Methane
  • Oxygen
  • Hydrogen
  • Nitrogen

Question 4

Question
Increasing levels of carbon dioxide have been linked to climate change
Answer
  • True
  • False

Question 5

Question
What is the main reason it's so hard to fully understand the Earth’s climate?
Answer
  • There are too many variables
  • We don’t understand particle physics well enough
  • Things have been oversimplified
  • Al Gore

Question 6

Question
Select the main FOUR effects of climate change
Answer
  • 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

Question 7

Question
Select six sensible ways to reduce carbon footprints
Answer
  • 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

Question 8

Question
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 - [blank_start]carbon dioxide gas[blank_end] from power stations can be stored underground increase/introduce taxes - penalise companies/individuals for releasing too many [blank_start]greenhouse gases[blank_end] carbon off-setting - plant more trees ([blank_start]reforestation[blank_end]) to convert [blank_start]carbon dioxide[blank_end] into [blank_start]oxygen[blank_end] carbon neutrality - companies introduce methods, such as [blank_start]planting trees[blank_end], to take out as much carbon dioxide as they put into the atmosphere. Overall the amount of [blank_start]carbon[blank_end] entering the atmosphere would be zero
Answer
  • greenhouse gases
  • reforestation
  • deforestation
  • oxygen
  • carbon dioxide
  • carbon dioxide gas
  • planting trees
  • carbon

Question 9

Question
[blank_start]carbon monoxide[blank_end] is a toxic, colourless and odourless gas, and it preferentially (and permanently) binds to haemoglobin in red blood cells instead of oxygen [blank_start]carbon particulates[blank_end] are unreacted carbon atoms that cause soot that can damage/clog up appliances, contributes to smog and global dimming [blank_start]sulfur dioxide[blank_end] is caused by sulfur impurities in fossil fuels like coal and crude oil can react with oxygen when the fuels are burned [blank_start]sulfur dioxide[blank_end] can dissolve in rain water to produce acid rain, which can damage structures, and wildlife habitats such as lakes and forests [blank_start]nitrogen oxides[blank_end] 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
Answer
  • carbon monoxide
  • carbon particulates
  • sulfur dioxide
  • nitrogen oxide
  • carbon particulates
  • carbon monoxide
  • carbon dioxide
  • carbon dioxide
  • sulfur dioxide
  • nitrogen oxide
  • carbon monoxide
  • nitrogen oxides
  • carbon oxides
  • sulfur oxides
  • sulfur dioxide
  • carbon dioxide
  • carbon monoxide
  • carbon particulates

Question 10

Carbon dioxide is a much more powerful greenhouse gas than methane.
Answer
  • True
  • False

Question 11

Question
Complete the diagram below
Image:
Atmosphere (binary/octet-stream)
Answer
  • Oxygen
  • Nitrogen
  • Carbon dioxide
