Which country emits the most carbon dioxide per person?

United States

Wasting less food is a way to reduce greenhouse gas emissions. T or F

True, wasting less food will produce less carbon dioxide and more food will be provided for people. More than 1/3 of food actually makes it to the table to be eaten otherwise it is spoiled and thrown out.

200
True or False: The Greenhouse Effect allows heat or infared energy from Earth's surface to pass directly out through the atmosphere and back into space.
False
200
What is the current level of carbon dioxide in the atmosphere today?
400 ppm
200

The ocean is NOT affected by climate change. T or F.

False, the ocean is affected by climate change as the temperature of the water gets warmer causing sea levels and currents to rise. When the currents rise more open land is covered making it sink.

Which country produces the most carbon dioxide in total each year?
China
300
Which planet has an atmosphere with an extreme greenhouse effect?
Venus

True or False: Leaving electronic devices plugged in or on standby when you are not using them increases your carbon footprint.
True

How responsible are humans for causing climate change? 

A )17%   

B) 64&

C) 6%

D) 80%

B, 64% of humans, Methane is responsible for 17% of man-made global warming, and nitrous oxide for 6%.

What has been happening to the concentrations of greenhouse gases in Earth's atmosphere over the past 200 years?
It has been increasing.

True or False: Photosynthesis releases carbon dioxide into the air.
False.

What is a cause of climate change?

    A ) Burning coal, oil and gas 

    B) Deforestation

    C) Increase of livestock farming

    D) All of the above

D, All of the above. Burning coal, oil and gas produces carbon dioxide and nitrous oxide. Cutting down forests loses the CO2 that is absorbed by the trees from releasing into the atmosphere. Increasing livestock farming will produce large amounts of methane when they digest their food.

What were carbon dioxide levels like during the last Ice Age?
much lower than they are today

True or False: Without the Greenhouse Effect, Earth's temperature would be unsuitable for most forms of life.
False
500
How long does carbon dioxide stay in the atmosphere once it has been emitted?
a few hundred years
