Carbon and Climate Change

Greenhouse gases, in moderate amounts, keep the Earth's temperature stable

• True
• False

Why is the increase of Greenhouse gasses a big issue?

• It causes climate change and increase in the global temerature 
• It can lead to a major increase in Greenhouses 
• It leads to more factories
• It causes a major decrease in people

This process keeps Earth's temperature suitable for life.

• Convection Currents
• Greenhouse Effect
• Albedo Effect
• Water Cycle

The main human activity that releases greenhouse gases is

• using bottled water
• burning fossil fuels
• texting on cellphones
• eating meat

Things you can do to help decrease global warming include:

• Eat more ice cream.
• Keep your freezer door open.
• Keep your air conditioner on high.
• Turn off your lights when you’re not using them.

What is the average weather for a particular time and region called?

• drought
• weather
• emissions
• climate

Climate change may have an impact on the following:

• Energy and human health
• Air quality, oceans, and coastal zones
• Agriculture
• All of the above

The graph below shows CO2 emissions and temperatures from 1909 to 1949.  What conclusion is best supported by the graph?

• There is no relationship between carbon dioxide concentrations and temperatures
• As carbon dioxide concentrations increase, temperatures increase
• As carbon dioxide concentrations increase, temperatures decrease
• As carbon dioxide concentrations decrease, temperatures increase

Why is the carbon cycle important?

• It continuously reuses and recycles carbon in the ecosystem
• It helps animals to digest food
• It takes nitrogen and oxygen out of the atmosphere

Carbon is used by plants during which process?

• Respiration
• Transpiration
• Photosynthesis
• Transportation
