Climate Change 1
What 3 things make Earth habitable?
1. The atmosphere traps heat from the sun
2. Earth's Systems (geosphere, biosphere, atmosphere) work together
3. Atmosphere - protects us from radiation from the sun
Finish the statement:
Global Average temperature increases when ....
Energy absorbed by Earth's Surface increases.
Which statement is most accurate?
Increased carbon dioxide or methane makes more sunlight enter Earth’s system.
Increased carbon dioxide or methane holds energy in the atmosphere permanently.
Increased carbon dioxide or methane redirects some energy that was leaving back to Earth’s surface.
3. Increased carbon dioxide or methane redirects some energy that was leaving back to Earth’s surface.
The job of the ozone layer
Protect Earth from Solar radiation
What are some effects of climate change? How many can you get?
Animals can lose their homes/become extinct
Plants can die/become extinct
More pollution is bad for all of us
Floods, droughts, an increase in natural disasters
More heat means more forest fires
More farms more methane
Less farms less food and increased prices
Which of these are evidence of global climate change?
a) Rising global temperatures
b) Melting ice caps/sea levels rising
c) More severe storms
d) All of the above
d) All of the above
If there is a decrease in the amount of carbon dioxide or methane, the amount of energy leaving the Earth system _____________, so less energy enters than exits.
increase
T/F
When the amount of carbon dioxide or methane in the atmosphere changes, the amount of energy absorbed by the surface does not change.
False
Complete the statement
When there is an increase in carbon dioxide in the atmosphere, _________________ which causes temperatures to _____________.
more energy enters than exits, increase
When energy in and out of the Earth system are equal it is called-
stability
A system can be stable, even as something is flowing into and out of the system. If this balanced flow is _____________, there may be changes to the system.
disrupted
Which two green house gases contribute the most to global warming?
Carbon dioxide and Methane
Complete the statement
Temperature increases if ....
more energy enters than exits.
As global warming continues, the intensity of what type of storm that hits coastlines is predicted to increase?
Hurricanes and Typhoons
The average weather for a region over a long period of time is. _______________.
Climate
Which of these is NOT an example of a greenhouse gas?
a) carbon monoxide
b) nitrous oxide
c) methane
d) carbon dioxide
a) carbon monoxide
What is the main cause of climate change?
Humans burning fossil fuels
T/F
It is possible for gases in the atmosphere to change the behavior of energy on Earth.
True
If Earth did not have an atmosphere filled with greenhouse gases, what would happen?
Earth's temperatures would be cold, oceans would freeze
All of the radiation from the sun is absorbed by the Earth.
True or False
False - Earth's atmosphere absorbs the radiation! You must be specific!
What is the greenhouse effect?
a) Gases are being trapped and making the temperature cooler
b) Gases are being trapped and making the temperature increase
c) Plants need a place to grow when the weather is cold
b) Gases are being trapped and making the temperature increase
What is the definition of climate change?
a) Changes in climate over long periods of time that can be caused by natural events or human activities.
b) when something becomes different over time
c) Overall tendency in a set of data over time.
a) Changes in climate over long periods of time that can be caused by natural events or human activities.
What happens when energy interacts with carbon dioxide or methane in the atmosphere?
It is redirected
How can global warming cause sea levels to rise?
Melting glaciers and ice caps
What caused the Eocene Period?
Increased Carbon dioxide and Methane in the atmosphere.
