methane
Trees are so important to our environment because they absorb (sink) which greenhouse gas?
methane
carbon dioxide
water vapor
oxygen
Why are too many greenhouse gases bad for the environment?
They cause trees to die.
They release heat and will be the cause of the next ice age.
They trap heat in our atmosphere causing the planet to warm up.
They are fossil fuels which pollute our environment.
What is global warming?
a gradual increase in the overall temperature of the earth's atmosphere.
a change in global or regional climate patterns
the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land.
The action of clearing a wide area of trees.
This is a molecule called:
Carbon monoxide (CO)
Carbon (C)
Carbon dioxide (CO2)
Carbon trioxide (CO3)
All living things on Earth are made of carbon. When we burn __________ _________ we release the carbon that had been trapped for millions of years into the atmosphere, creating CO2.
global warming
fossil fuels
banned plastics
giant cars
For over 800,000 years, Earth had an average CO2 level of _____ PPM. After the industrial revolution (the beginning of the Anthropocene) this rose to over _____ PPM.
100 and 200
100 and 400
300 and 400
400 and 500
Paleoclimatologists study the climate and its changes throughout Earth’s history. What observation by paleoclimatologists led scientists to predict that the average temperature of the planet is rising due to the combustion of fossil fuels?
increases in average temperatures with increasing volcanic activity
direct correlation between atmospheric carbon dioxide level and global temperature
a recent rise in global temperature as atmospheric pollution increased
changes in sea level that correspond to average global temperature
