What is the difference between weather and climate?
They are the same.
Weather is day to day, while climate is observed over a long periods.
Climate is day to day, while weather is observed over a long period.
Weather changes, while climate does not.
The shape of Earth’s orbit goes from more circular to …
Perfectly circular
Oval-shaped
Rectangular
None of the above
Of the roles that greenhouse gases (such as carbon dioxide and methane) have in Earth's climate system, which is not accurate?
help prevent the earth from cooling substantially each night
allows for light (short-wavelength) energy to travel through the atmosphere.
help trap and hold thermal (short-wavelength) energy in the atmosphere
helps keept the Earth at a moderate 59 degrees Farenheit.
The greenhouse effect is caused by…
Too much heat in the atmosphere
Too much sunshine reaching Earth
Greenhouse gases in the lower atmosphere absorbing radiation from the Earth's surface, and preventing much of it escaping into space
Greenhouse gases in the lower atmosphere absorbing solar radiation
Earth is currently in an interglacial period (a period of milder climate between Ice Ages). If there were no human influences on climate, scientists say Earth’s current orbital positions within the Milankovitch cycles predict our planet should be cooling, not warming, continuing a long-term cooling trend that began 6,000 years ago.
True
False
There are only two different types of climates found on Earth: tropical and desert
True
False
Based on this graph, what is the relationship between carbon dioxide and global temperature?
There is no relationship between carbon dioxide and temperature.
If carbon dioxide increases, temperature decreases.
If carbon dioxide increases, temperature increases.
