Speed
how fast an object is moving
Which of the following statements BEST describes the locations of volcanoes?
Most volcanoes are located along the edges of some continents or in chains off the
coast of continents.
Some plate boundaries have
active volcanoes but some don't, and almost all volcanoes are at boundaries.
The typical speed of a plate is
a few centimeters per year.
An atmospheric instability causes a column of air to rotate.
Tornado
A moist mass of air over warm ocean water condenses as it rises, forming a
massive spinning storm.
hurricane
This type of storm is common at cold fronts and often produces lightning.
Thunderstorms
This is the most violent storm on Earth.
tornadoes.
A hurricane has an
eye in the center that is very calm.
Lightning is an
electric glow that can be seen during a storm.

Differences in temperature within Earth and within the plates result in
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
fog
Which radiation can greenhouse gases absorb that nitrogen and oxygen cannot?
Greenhouse gases can absorb infrared radiation, which nitrogen and oxygen
cannot.
Which of the following are considered greenhouse gases?
carbon dioxide and methane
Which kind of plate boundary produced the Himalayas?
Two plates pushed into each other to push the land upward and generate a
mountain range.
Greenhouse gases in Earth's atmosphere
absorb infrared radiation emitted by the ground.
After absorbing incoming solar radiation, Earth emits mostly __________, which
is the radiation associated with heat.
infrared radiation
The greenhouse effect __________.
helps keep Earth's surface sufficiently warm for life to exist
The greenhouse effect occurs because greenhouse gases __________.
absorb infrared radiation emitted by the surface
If more water vapor was present in Earth's atmosphere, what would happen to
Earth's temperature?
The temperature would increase.
The most abundant greenhouse gas in volcanic eruptions is __________.
NURS3320
, NURS3320
water vapor
Solar radiation __________.
has been increasing over the past several billion years
Which of the following is a natural process that adds carbon dioxide to the
atmosphere?
respiration
Plants remove carbon dioxide from the atmosphere and cutting down forests
increases the rate of global warming.
If the mass of the box increases, but the force remains the same, the box's
acceleration will
decrease
Why does San Francisco have earthquakes?
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,
a given force will produce less acceleration.
When force increases
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
is zero
Friction is the force that
opposes motion of an object
A force of friction does not exist if
two objects are not touching.
If the distance is doubled, the force of gravity
