Question 2

The moist greenhouse effect refers to

Accepted Answer

A)  the warming process by which water vapor rises into the upper atmosphere above the ozone layer where it is then broken apart by ultraviolet radiation 
B)  the point at which water is evaporating from the surface at a faster rate than it is condensing 
C)  the natural greenhouse effect due to clouds of water vapor in the lower atmosphere 
D)  an enhanced greenhouse effect above tropical regions of the Earth's surface

Question 3

If the Earth were to be moved to where Venus is today,

Accepted Answer

A)  the oceans would evaporate, blocking light from the Sun and causing global temperatures to fall 
B)  carbon dioxide would be released from the oceans leading to higher temperatures but liquid water could still exist on the surface 
C)  the oceans would evaporate slightly producing a slightly warmer, more humid planet 
D)  the oceans would evaporate and carbonate rocks would decompose producing a runaway greenhouse effect much more severe than the one that exists on Venus today

Question 5

The Moon is in the habitable zone of the Sun at the same distance as the Earth but is not habitable. How can this be?

Accepted Answer

A)  the Moon did have water on its surface in the past, but it was destroyed by high-energy particles from the Sun 
B)  the Moon has never had water on its surface at any time 
C)  the Moon is too small to retain an atmosphere necessary for liquid water to be stable 
D)  the Moon did have water on its surface in the past, but it was blasted off the surface by impacts
