- 21%- Oxygen
- 0.96%- Noble gases
- ).04%- Carbon Dioxide
2
Q
Define Air Pollutants
A
Air pollution is the introduction of unwanted and harmful chemicals into the atmosphere
3
Q
Describe the source and Harmful Effect of Sulfur Dioxide
A
- It is a colorless gas with pungent odour
- Combustion of Fossil Fuels and/or Volcanic Eruptions
- breathing difficulties
- React with rainwater to form acidic rain
- Corrodes buildings and Structures made from limestone
4
Q
Nitrogen Oxides
A
- Vehicle combustion
- Lightning
- Breathing difficulties
4.Reacts with rainwater to form acidic rain - Corrodes buildings and structures made from limestone
5
Q
Carbon Monoxide
A
- Incomplete combustion of carbon-based fuels
- Lowers our body’s ability to transport oxygen to the rest of the body
6
Q
Methane
A
- Bacteria decay of organic structures
- Waste gases from cattle
- A major greenhouse gas that leads to global warming
7
Q
Unburnt Hydrocarbons
A
- Vehicle combustion engines
- Eye and respiratory irritation
8
Q
Ozone
A
- Lightning
- Eye and respiratory irritation
9
Q
Acid Rain
A
- As the Acidic rainwater falls onto the buildings and sculptures, it corrodes the metal or dissolves the stone that is exposed
10
Q
Carbon Cycle
A
- Describes a set of processes that regulates the amount of carbon dioxide in the atmosphere
11
Q
Global Warming
A
- Is the increase in the average temperature of the Earth’s surface due to increasing amounts of greenhouse gases in the atmosphere
12
Q
Climate Change and other consequences
A
- Change in Rainfall Patterns: Shifting wind patterns can lead to changes in rainfall patterns. (Not enough rainfall or too much rainfall)
- Heat waves: Some area may be extremely hot
- Tropical storms: They formed over warm water
- Glacial retreat and melting of polar ice caps: Sea levels would rise and cause flood
