Why is there less total evaporation from oceans than from freshwater sources?
Freshwater sources have less surface area than oceans.
Oceans have less surface area than freshwater sources.

divergence, rising air
convergence, sinking air
What is the best evidence to support that an occluded front is occurring?
A warm and cold front collide and remain motionless.
Cool air sinks and warm air rises, creating a convection current.
A warm front pushes into the area, creating clear skies and warm weather.
A cold front pushes warm air upward, and the cold front collides with a cold front.
A thunderstorm with low barometric pressure and high-speed winds forms over land. Which type of weather might develop there?
tornado
hurricane
cold and snowy
sunny and clear
Which statement best describes the general movement of air masses?
They move from areas of high altitude to areas of low altitude.
They move from areas of low temperature to areas of high temperature.
They move from areas of high humidity to areas of low humidity.
They move from areas of high pressure to areas of low pressure.
Which choice best explains why a low-pressure system and a high-pressure system create different weather conditions?
In a low-pressure system, air sinks, creating fair weather. In a high-pressure system, air rises, creating storms.
In a low-pressure system, air rises, creating storms. In a high-pressure system, air sinks, creating fair weather.
In a low-pressure system, air rises, creating fair weather. In a high-pressure system, air sinks, creating storms.
In a low-pressure system, air sinks, creating storms. In a high-pressure system, air rises, creating fair weather.
Why is a low-pressure system generally associated with cloudy and rainy weather?
As cool air rises, it becomes colder, generating freezing rain.
As warm air rises, it cools in the atmosphere, creating condensation.
As cool air rises, it warms in the atmosphere, generating severe weather.
As warm air rises, it gets warmer in the atmosphere, creating precipitation.
The air pressure at City A is 1,018 mb, and the air pressure at City B is 980 mb. What will most likely occur due to the pressure gradient present between City A and City B?
The high-pressure system at City A will create winds that blow toward the low pressure system at City B
There will be clear skies and no winds observed at City A and City B.
The winds created will flow away from City A and City B.
The low-pressure system at City B will create winds that blow toward the high pressure system at City A.
Which clouds are common in winter and usually indicate cold but fair weather?
altostratus
cirrocumulus
stratocumulus
cirrus
Why is the moisture of cirrus clouds mostly in the solid state?
The density of the clouds creates solidified crystals.
The higher altitude allows for lower temperatures, leading to frozen water crystals.
The higher altitude allows for lower temperatures, leading to frozen water crystals.
The higher altitude and farther distance from Earth’s surface mean there is less gravity to form ice crystals.
Which factors best determine the variety of climate zones on Earth?
