Global Warming Flashcards
What is evaporation?
When the heat of the sun causes water to turn to water vapor
What is condensation?
As the water vapor moves higher in the atmosphere, it cools down and condenses to form tiny droplets of water
What is precipitation?
The tiny droplets of water keep on accumulating in the clouds until it can no longer accommodate any more, the water is released from them
What is run-off?
The water that falls back to the surface of the earth either stays on the surface or flows off the surface into the water bodies
What is transpiration?
When the water absorbed by the plants is evaporated from leaves and stem
What is infiltration?
When the water on the surface of the earth seeps down the ground
How does carbon dioxide enter the atmosphere?
Respiration and combustion
What are the two ways nitrogen gas can be fixed?
Through lightning and nitrogen fixing bacteria
What is ammonification?
Atmospheric nitrogen produced into ammonia
What is the human impact to phosphorus cycle?
Introduction of synthetic fertilizers
High concentration of phosphate in water system can lead to?
Eutrophication
What is global warming?
An average increase in the temperature of the atmosphere near the earth’s surface and in the troposphere, which can contribute to changes in global climate patterns
What are the two categories of causes of global warming?
Man-made and natural causes
What are the causes of global warming?
Burning of fossil fuels
Power plants generate electricity
Transportation fuels for transport
Industrial processes
Other greenhouse gases emission
Agriculture
