Question 1

Question
Originally, what was the earths surface?
Answer
  • Molten
  • Water

Question 2

Question
What 3 GASES do volcanoes give out?
Answer
  • Carbon Dioxide (CO2) Nitrogen (N) Water (H2O)
  • Carbon Dioxide (CO2) Oxygen Carbon Particulates (C)

Question 3

Question
What happened to the atmosphere when plant life formed?
Answer
  • There was less CO2 in it and more O2 because as the plants went through PHOTOSYNTHESIS they converted the Carbon Dioxide into Oxygen.
  • Nothing happened, the atmosphere stayed the same.

Question 4

Question
What happened to the dead plants?
Answer
  • They got buried underground and the Carbon they'd taken from the CO2 got put in SEDIMENTARY rocks as INSOLUBLE CARBONATES and FOSSIL FUELS
  • They rotted or got eaten by animals

Question 5

Question
Name the gases and their amounts in today's atmosphere?
Answer
  • Nitrogen (N)- 78% Oxygen (O)- 21% Argon (Ar)- 1% Carbon Dioxide (CO2)- 0.04% Trace other gases
  • Nitrogen(N)- 90% Oxygen (O)- 21% Carbon Dioxide (CO2)- 1 % Sulfur Gas (S)- 17%

Question 6

Question
Which Pollutants does Human Activity add to the Atmosphere?
Answer
  • Carbon Dioxide Carbon Monoxide Carbon Particulates Sulfur Dioxide Nitrogen Oxides
  • Nitrogen Oxides Sulfur Dioxide Argon Oxygen

Question 7

Question
What are the two main sources of Pollutants?
Answer
  • Burning Fuels (Power Stations and Vehicles) Nature (Volcanic Activity)
  • Cows Gas Energy you use biking to school

Question 8

Question
What/How does CARBON MONOXIDE, SULFUR DIOXIDE and CARBON DIOXIDE do/effect people and the planet?
Answer
  • Carbon Monoxide- Cuts off the Oxygen supply your blood cells carry. (DIRECT HARM) Sulfur Dioxide- Causes Acid rain which kills fish which people eat (INDIRECT HARM) Carbon Dioxide- part of Climate Change which is caused by Pollution and creates World Problems. (INDIRECT HARM)
  • Carbon Monoxide- Given out by Cows and it the cause of Global Warming (INDIRECT) Sulfur Dioxide- Stains buildings and burns skin when it falls as from the sky as rain and soot (INDIRECT) Carbon Dioxide- Kills people and the planet (DIRECT)

Question 9

Question
In chemical reactions, can atoms disappear?
Answer
  • Yes, because some are lost because the just get lost
  • No, because the end product always has the same amount of each atom in and no mass is lost which also proves no atoms are lost because if they were the mass would be less.

Question 10

Question
What is a Hydrocarbon? (eg. Crude Oil)
Answer
  • Fossil Fuels made of Hydrogen and Carbon atoms formed from the remains of dead plants and animals that have been left millions of years.
  • A Carbon Atom that has been pressurised with Hydrogen to form dead plant cells

Question 11

Question
What is OXIDATION and REDUCTION?
Answer
  • Oxidation- When Oxygen gets added to something Reduction- When Oxygen is taken away from something
  • Oxidation- Doesn't exist Reduction- Getting smaller

Question 12

Question
How can CO2 be removed from the atmosphere?
Answer
  • Plants- Through Photosynthesis Absorbed into Rivers, Lakes and other forms of water
  • High powered air suction Carbon extracting

Question 13

Question
Sulfur comes from IMPURITIES in fuel. When it burns with the Fuel, what does it combine with in the air and what does it make?
Answer
  • Oxygen and Sulfur Dioxide
  • Carbon Dioxide and Sulfur Carbonate

Question 14

Question
Nitrogen Pollution is formed from nitrogen in the air when Fuel is burnt. Name both Nitrogen Oxides (NOx) and an example of when they form and are released?
Answer
  • Nitrogen Dioxide, Nitrogen Monoxide and Car Engines
  • Nitrogen, Nitrogen Monoxide and Coal Mining.

Question 15

Question
Although we produce a lot of pollution there are ways to reduce the amount we make. Name one place we can reduce pollution from, a way in which cars now lower there emission and two alternate energy sources?
Answer
  • Power Stations (Remove the sulfur from burning materials and reduce amount of Fossil Fuels used), Cars are not fitted with Catalytic Converters which converts Nitrogen Monoxide in harmless Nitrogen and Oxygen, and finally Wind Power (Turbines) and Solar Panels.
  • Out walking the dog (Use less materials in products) , They don't and Electric Powered cars
