U2 Atmosphere Flashcards
what is the natural greenhouse effect?
Radiation reflected from the Earth’s surface is absorbed by gases in the atmosphere
Most abundant gases in the atmosphere
Nitrogen, oxygen, carbon dioxide
Process of generating electricity from wind turbines
Kinetic energy (wind) turns a turbine which turns the energy to electrical energy
What requirements do you need for a wind farm?
- Steady wind flow
- exposed site
- easily accessible
- near to the National Grid
Disadvantage of wind power
Visual or noise pollution for nearby residents
Lack of wind may cause unstable source of electricity
Advantages of wind power
Renewable
No GHG emissions
What is a use of Nitrogen
Fertilisers
Explosives
Dyeing clothes
What is a use of Oxygen
Welding Life support (oxygen tanks)
Name a greenhouse gas
Carbon dioxide
Methane
Water vapour
Carbon monoxide
What does anthropogenic mean?
Man made
What is an anthropogenic greenhouse gas?
Transportation (planes and cars)
Industry - factories and power plants
Domestic - coal and oil powered heating
What happens to the atmosphere with increased greenhouse gases?
More warming in the atmosphere, as the gases trap the sun’s radiation
Give an effect of Climate Change
- Increased storms
- Increase droughts and floods
- Wildfires
- Ice caps and glaciers melting
