Differences in temperature within Earth and within the plates result in - ANSWER:
processes that move plates.
A low-lying cloud of small water droplets that reduces visibility to less than 1 km
(0.62 mi) is called - ANSWER: fog
Which radiation can greenhouse gases absorb that nitrogen and oxygen cannot? -
ANSWER: Greenhouse gases can absorb infrared radiation, which nitrogen and
oxygen cannot.
Which of the following are considered greenhouse gases? - ANSWER: carbon dioxide
and methane
Which kind of plate boundary produced the Himalayas? - ANSWER: Two plates
pushed into each other to push the land upward and generate a mountain range.
, Greenhouse gases in Earth's atmosphere - ANSWER: absorb infrared radiation
emitted by the ground.
After absorbing incoming solar radiation, Earth emits mostly __________, which is
the radiation associated with heat. - ANSWER: infrared radiation
The greenhouse effect __________. - ANSWER: helps keep Earth's surface
sufficiently warm for life to exist
The greenhouse effect occurs because greenhouse gases __________. - ANSWER:
absorb infrared radiation emitted by the surface
If more water vapor was present in Earth's atmosphere, what would happen to
Earth's temperature? - ANSWER: The temperature would increase.
The most abundant greenhouse gas in volcanic eruptions is __________. - ANSWER:
water vapor
Solar radiation __________. - ANSWER: has been increasing over the past several
billion years

acceleration will - ANSWER: decrease
Why does San Francisco have earthquakes? - ANSWER: San Francisco lies along the
boundary between the North American plate and the Pacific plate. At this location,
they are grinding past each other, occasionally slipping suddenly along a transform
fault.
If the mass of an object increases, - ANSWER: a given force will produce less
acceleration.
When force increases - ANSWER: acceleration also increases, according to Newton's
second law.
The net force acting on an object moving in a straight line at a constant speed -
