Weather Review Part 1

How does low air pressure affect the formation of clouds and precipitation?

• Low air pressure has no effect on the formation of clouds and precipitation.

• Low air pressure causes air to stay stagnant, resulting in the dissipation of clouds and precipitation.

• Low air pressure causes air to rise and cool, leading to the condensation of water vapor into clouds and precipitation.

• Low air pressure causes air to sink and warm, preventing the formation of clouds and precipitation.

Explain the process of sea and land breeze formation.

• Sea and land breezes are caused by the movement of ocean currents.

• Sea and land breezes are caused by the gravitational pull of the moon.

• Sea and land breezes are caused by the temperature difference between the land and the sea.

• Sea and land breezes are caused by the rotation of the Earth.

What instrument measures wind speed and direction?

• hygrometer

• barometer

• thermometer

• anemometer

When low pressure is present, what type of weather might you expect to occur?

• clear skies and light winds

• rainy or stormy weather and strong winds

• temperature rising

• temperature falling

What type of weather may occur with high pressure?

• clear skies and light winds

• temperature rising

• temperature dropping

• rainy or stormy weather and strong winds

How are weather and climate different?

• weather is how cold it is, and climate is if there is precipitation

• weather can be predicted and climate cannot

• weather is the day-to-day state for a given area, and climate is the average weather conditions over a long period of time

• weather and climate are the same, it just depends on which word you choose to use

Match the following

• grow in height and darken on the bottom; may produce thunderstorms

• Cirrus

• smooth, gray clouds that block sunlight; often means light rain

• Stratus

• fluffy, white clouds with flat bottoms; usually mean fair weather

• Cumulonimbus

• feathery, wispy clouds; fair weather may change into rain or snow later in the day

• Cumulus

The image shows a tool that is used to measure air pressure. What is it called?

• anemometer

• barometer

• thermometer

• rain gauge

The graphic shows a common daily wind pattern. 

Which term best describes the wind pattern in the graphic?

• land breeze
• sea breeze
• trade wind

The arrow above the water is coming down and is blue because

• the water is warm so it warms the air and warm air sinks.

• the water is cold so it warms the air and cool air sinks.

• the water is cold so it cools the air and cool air sinks.

• the water is warm so it warms the air and cool air sinks.
