Resource summary

Question 1

Question
Which of the following gases was probably a major part of the early atmosphere?
Answer
  • carbon dioxide, oxygen
  • nitrogen, carbon dioxide
  • oxygen, nitrogen
  • water vapour, argon

Question 2

Question
In the modern day atmosphere, oxygen takes up about 21%. What is the approximate percentage of nitrogen? [blank_start]78[blank_end] %
Answer
  • 78

Question 3

Question
What is the name of the atmospheric process which keeps the Earth warm by absorbing radiation from the Sun?
Answer
  • Global warming
  • Greenhouse effect
  • Climate change
  • Carbon footprint

Question 4

Question
What is the name of the process which separates crude oil into simpler mixtures of hydrocarbon compounds?
Answer
  • Fractional distillation
  • Crystallisation
  • Cracking
  • Polymerisation

Question 5

Question
Complete the diagram below
Answer
  • crude oil
  • gases
  • petrol
  • kerosene
  • diesel
  • fuel oil
  • bitumen
  • heating
  • cooling
  • heating oil
  • longer chains condense here
  • shorter chains condense here

Question 6

Question
What term could be used to describe a resource which is being made more slowly than it is being used up?
Answer
  • finite
  • infinite
  • renewable
  • sustainable

Question 7

Question
During complete combustion of butane, what are the chemical products? water and [blank_start]carbon dioxide[blank_end]
Answer
  • carbon dioxide

Question 8

Question
Sulfur dioxide gas produced by the combustion of fossil fuels is generally responsible for producing [blank_start]acid rain[blank_end]?
Answer
  • acid rain

Question 9

Question
When fuels burn they are reacting with the [blank_start]oxygen[blank_end] in the air. If there is an abundance of [blank_start]air[blank_end], then [blank_start]complete combustion[blank_end] will take place. This means [blank_start]carbon dioxide[blank_end] is produced. If they isn't enough air, then [blank_start]incomplete combustion[blank_end] happens and [blank_start]carbon monoxide[blank_end] is made.
Answer
  • oxygen
  • hydrogen
  • air
  • complete combustion
  • incomplete combustion
  • carbon dioxide
  • carbon monoxide

Question 10

Question
Which of the following is not an advantage to hydrogen as a fuel cells (vs petrol/diesel)?
Answer
  • chemical energy is converted straight to electrical energy, compared to a fossil fuel which converts chemical energy to heat energy first (so fewer transfer stages, and less 'lost' energy)
  • there are less pollutants - in fact no pollutants, as water is only product
  • rechargeable batteries have a limit on how many times they can be recharged, whereas fuel cells can keep going as long as they're refilled
  • currently hydrogen gas is produced from hydrocarbons, or electrolysis of water (requires use of electricity, generally powered by burning fossil fuels)

Question 11

Question
Rising temperatures due to the increase of [blank_start]carbon dioxide[blank_end] and methane in the atmosphere will lead to: ice at the South Pole and in glaciers will melt, causing global sea levels to [blank_start]rise[blank_end] - this will lead to increased, and/or permanent [blank_start]flooding[blank_end] in some areas animals will move away from their 'natural' habitats to find [blank_start]cooler[blank_end] areas to live, and some plants/animals may become [blank_start]extinct[blank_end] if they cannot survive the warmer temperatures weather patterns will begin to change with some areas becoming [blank_start]drier[blank_end], and others much wetter - and even more extreme weather events like more frequent severe [blank_start]storms[blank_end] and heat waves/droughts wildlife, and growth of [blank_start]crops[blank_end], will be affected by the ever-changing weather systems as more carbon dioxide is released, more will [blank_start]dissolve[blank_end] into water systems lowering the [blank_start]pH[blank_end] - more acidic waters can harm the organisms that live in them
Answer
  • carbon dioxide
  • rise
  • flooding
  • cooler
  • extinct
  • drier
  • storms
  • crops
  • pH
  • dissolve

Question 12

Question
The oldest temperature records for central England date back to 1659, but cannot be used to assess global temperature changes as they are only from one place. Temperature records from around the world have only existed from about 1880. These measurements were also not very accurate.
Answer
  • True
  • False

Question 13

Question
Modelling climate change is easy.
Answer
  • True
  • False
