Climate Change Flashcards
What is the troposphere?
The troposphere is closest to the Earth and contains mainly atmospheric gases.
What is the atmosphere?
The atmosphere is a mixture of gases that’s around the Earth. It is mainly 2 element, nitrogen and oxygen. There are smaller amounts of other substances including carbon dioxide and argon.
What is a mixture?
A mixture is made up of substances with two or more elements or compounds not chemically joined together.
What percentage dose nitrogen and oxygen make up of our atmosphere?
Nitrogen: 78%
Oxygen: 21%
What is the order of the green house effect?
- infrared radiation comes from the Sun.
- The earth absorbs some radiation.
3.The earth reflects some radiation. - Greenhouse gases trapped the radiation only some escape.
- increases in greenhouse gases leads to pollution and deforestation.
- This Causes more radiation to be absorbed and trapped by the greenhouse gases.
- Temperature of the Earth rises even more.
What is the carbon cycle?
Carbon enters the atmosphere as carbon dioxide from respiration and combustion.
Carbon dioxide is absorbed by producers to make glucose in photosynthesis.
Animals feed on the plant passing the carbon compounds along the food chain. Most of the carbon they consume is exhaled as carbon dioxide that was formed during aerobic respiration. The animals and plants eventually die.
Decomposers break down the dead organisms and return the carbon in their bodies to the atmosphere as carbon dioxide by respiration. In some conditions, decomposition is blocked. The plant and animal material may then be available as fossil fuel in the future for combustion.
What is global warming?
Scientist have been measuring and recording air temperatures. They have collected this data and calculated average worldwide temperatures for each year. That has been a gradual increase in our temperatures throughout the years.
What is combustion and what is the equation?
Combustion is when a fuel quickly reacts to oxygen.
Fuel + Oxygen ➡️ Water + Carbon dioxide
What is respiration and what is the equation?
Respiration is when glucose and oxygen mix together to make energy.
Glucose + Oxygen ➡️ Water + Carbon Dioxide
