Physical Science 2.3

Multiple Choice

Watch the video, then answer the question.

In which direction are objects deflected due to the Coriolis Effect?

• To the right

• To the left

Multiple Choice

What creates the Coriolis Effect?

• Earth's orbit around the Sun

• Earth rotating on its axis.

• The pull of gravity from the Moon

Multiple Choice

In which direction will winds traveling from the north pole towards the equator be deflected due to the Coriolis Effect?

• From west to east

• From east to west

Multiple Choice

Watch the video, then answer the question.

What happens to the air at the equator?

• The air is rising, creating areas of high pressure

• The air is sinking, creating areas of low pressure.

• The air is rising, creating areas of low pressure.

• The air is sinking, creating areas of high pressure.

Multiple Choice

Why are rainforests found near the equator?

• Because the moist, warm air rises at the equator, then cools as it rises, resulting in lots of rain.

• Because dry, warm air rises at the equator, then cools as it rises, resulting in lots of rain.

• Because moist, warm air sinks at the equator, bringing lots of rain with it.

Multiple Choice

Why are deserts found at 30 degrees latitude?

• Because warm, moist air rises at 30 degrees latitude and takes all of the moisture with it.

• Because warm, dry air rises at 30 degrees latitude and there is no moisture left.

• Because dry air sinks at 30 degrees latitude.

Multiple Choice

In what direction do the trade winds blow?

• From west to east

• From east to west

Multiple Choice

In what direction do the prevailing westerlies blow?

• From east to west

• From west to east

Multiple Choice

Watch the video, then answer the question.

Where do jet streams form?

• Where cold air masses form

• Where warm air masses form.

• Where warm and cold air masses meet, high in the troposphere.

Multiple Choice

In which direction do jet streams flow?

• From east to west

• From west to east

Multiple Choice

When do jet streams travel the fastest?

• In the summer

• In the spring

• In the fall

• In the winter

Multiple Choice

When does a Nor'easter form?

• When the jet stream bring warm air up from the equator.

• When the jet stream brings cold air down from Canada, over the Atlantic ocean, and into the northeastern states.

• When the jet stream brings cold air down from the north pole, over the Pacific ocean, and into the western United States.

Multiple Choice

Which way does a land breeze blow?

• From the sea to the land

• From the land to the sea

• South to North

Multiple Choice

Land heats up and cools relatively

• slowly

• quickly

Multiple Choice

Water heats up and cools more slowly than

• Land

• Air

Multiple Choice

What causes wind?

• differences in pressure
• conduction currents
• density
• tropical currents

Multiple Choice

What causes warm air to rise?

• the fact that it's less dense than cold air 
• The fact that it weighs more than cold air 
• The fact that it has higher pressure than cold
• the fact that its more dense than cold air 

Multiple Choice

Cold air is ____________ than warm air and ___________.

• more dense; sinks

• less dense; rises

• more dense; rises

• less dense; sinks

Multiple Choice

When cool air sinks, it creates areas of __________ pressure.

• high

• low

Multiple Choice

When warm air rises, it creates areas of __________ pressure.

• high

• low

Local Winds:

Sea and Land Breezes

*caused by: CONVECTION

*Which means density differences --

warm rising/cold sinking

Multiple Choice

A sea breeze occurs during the

• night

• day

• high tide

• low tide

Another Local Wind: Rain shadow effect
Mountain Breeze
Valley Breeze

• occurs in mountainous regions

Multiple Select

Click on the following facts that are CORRECT.

Click the image to make it bigger.

• The leeward side of the mountain is a dry climate.

• The windward side of the mountain is desert climate.

• When the air/wind rises it forms clouds.

• The windward side of the mountain is a wet climate.

• This local wind is caused conduction.

Landforms

The presence of mountains affects the climate of a region. There are more rainfalls in mountain than in low lying areas. The air becomes cold causing moist air to condense and fall out as rain as the wind is forced uoward to higher ground. During the day the air rises as it is warmed by the sun. It moves down the mountain at night

Multiple Select

What are some of the places on Earth where the rain shadow occurs?

• Australia 

• Washington State

• Hawaii

• Great Lakes

• Appalachian Mountains
