Weather Study Guide

Which term best describes the circulation of air and water in the atmosphere?

• condensation

• convection

• evaporation

• sublimation

What is the main source of energy for weather everywhere on Earth?

• wind

• gravity

• the sun

• precipitation

Which process within the water cycle occurs just as clouds begin to form in the atmosphere?

• condensation

• evaporation

• precipitation

• transpiration

Which best explains how convection affects the atmosphere?

• Sun heats Earth and then warm air rises to heat the atmosphere

• Ocean currents move warm air upward creating a greenhouse effect

• Earth is heated by sea breezes and then warm air rises to heat the atmosphere.

• Curving ocean currents move cold water from the Arctic to the equator, causing air to rise.

What is the best evidence to support that an occluded front is occuring?

• A warm and cold front collide and remain motionless

• Cool air sinks and warm air rises, creating a convection current.

• A cold front pushed warm air upward, and the cold front collides with a cold front

• A warm front pushes into the area, creating clear skies and warm weather.

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 high pressure to areas of low pressure

• They move from areas of high humidity to areas of low humidity

• They move from areas of low temperature to areas of high temperature

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.

Which type of large storm most likely happens when a low-pressure system forms over the ocean in the summer?

• hail

• hurricane

• thunderstorm

• tornado
