Earth Flashcards
Name two types of activities caused by humans
Deforestation and combustion
What does deforestation result in
Less oxygen given out in our atmosphere
What does combustion result in
Thickens amount of carbon dioxide in our environment
Where does photosynthesis take place
In plants which takes in carbon dioxide
What does sulfur dioxide and carbon dioxide cause
Climate change and rising sea levels
Explain why scientists are concerned about the release of the greenhouse gases such as carbon dioxide in our atmosphere
Excessive CO2 in atmosphere
Suggest one way to reduce amount of greenhouse gases in the atmosphere due to electricity generation
Solar energy
What is enhancing in global warming
The greenhouse effect which leads to global warming
What do hotter summers lead to because of Climate change
Droughts and increased rainfall, flooding
What else is effected by global warming
Higher rate of melting of ice caps, polar sea ice and glaciers
Rising sea levels
How do you calculate percentage yield
= actual yield
——————— X 100
Predicted yield
Name two natural processes that have allowed carbon dioxide and oxygen to remain the same for thousands of years
Respiration and photosynthesis
Name the gas responsible for global warming
Carbon dioxide
Name the gas responsible for acid rain
Sulfur dioxide
What does combustion do
Thickens the amount of carbon dioxide in our environment
