Atmosphere in Motion

The layer of the atmosphere where we live is the

• stratosphere

• mesosphere

• troposphere

• stormosphere

As air heats up, it rises, allowing cold air to flow in from elsewhere. This causes

• a wind

• a thunderstorm

• a frost

• a front

A specific volume of warm air weighs less than an equal volume of cold air because [best answer]

• cold air is under higher pressure

• warm air is less dense

• cold air is full of moisture

• warm air forms over the ocean

During the water cycle, some moisture enters the atmosphere through the release of water vapor by plants. This process is called

• precipitation

• evaporation

• condensation

• transpiration

The sun's heat reaches Earth through

• convection

• conduction

• solar wind

• radiation

The Coriolis effect is caused by

• the rotation of Earth on its axis

• the difference in density between warm and cold air

• the gravitational pull between the Earth and Moon

• the revolution of the Earth around the Sun

Which of the following fronts is most often associated with steady rain that lasts a day or more

• a warm front

• a stationary front

• an occluded front

• a cold front

The most abundant gas in the atmosphere is

• nitrogen

• oxygen

• water vapor

• helium

The greater the difference in air pressure

• the slower the wind will blow

• the greater the wind speed

• the less the evaporation

• the less clouds in the sky

When a warm air mass meets a cold air mass

• The cold air mass will rise above it

• The cold air mass will mix with the warm air mass

• The warm air mass will sink under the cold air mass

• The warm air mass will slide over the cold air mass.
