Originally, what was the earths surface?
Molten
Water
What 3 GASES do volcanoes give out?
Carbon Dioxide (CO2) Nitrogen (N) Water (H2O)
Carbon Dioxide (CO2) Oxygen Carbon Particulates (C)
What happened to the atmosphere when plant life formed?
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.
What happened to the dead plants?
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
Name the gases and their amounts in today's atmosphere?
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%
Which Pollutants does Human Activity add to the Atmosphere?
Carbon Dioxide Carbon Monoxide Carbon Particulates Sulfur Dioxide Nitrogen Oxides
Nitrogen Oxides Sulfur Dioxide Argon Oxygen
What are the two main sources of Pollutants?
Burning Fuels (Power Stations and Vehicles) Nature (Volcanic Activity)
Cows Gas Energy you use biking to school
What/How does CARBON MONOXIDE, SULFUR DIOXIDE and CARBON DIOXIDE do/effect people and the planet?
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)
In chemical reactions, can atoms disappear?
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.
What is a Hydrocarbon? (eg. Crude Oil)
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
What is OXIDATION and REDUCTION?
Oxidation- When Oxygen gets added to something Reduction- When Oxygen is taken away from something
Oxidation- Doesn't exist Reduction- Getting smaller
How can CO2 be removed from the atmosphere?
Plants- Through Photosynthesis Absorbed into Rivers, Lakes and other forms of water
High powered air suction Carbon extracting
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?
Oxygen and Sulfur Dioxide
Carbon Dioxide and Sulfur Carbonate
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?
Nitrogen Dioxide, Nitrogen Monoxide and Car Engines
Nitrogen, Nitrogen Monoxide and Coal Mining.
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?
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.
