Atmospheric circulation

Cold air ...

• sinks

• rises

Where experiences warm temperatures with clouds and rain?

• The equator

• The sub-tropical highs

• The sub-polar lows

• The polar highs

True or false - warm air rises, cools and condenses and forms clouds, this is called low pressure

• True

• False

What are trade winds?

• Surface winds blowing towards the equator

• Atmospheric winds

• Winds blowing away from the equator

• Low pressure winds

Why are there global winds?

• because the cold air sinkes from the poles to the equator
• because the earth is rotating from east to west
• because the sun heats the air at the equator more than anywhere else on earth

How does the Coriolis Effect influence hurricanes and cyclones

• determines how powerful they will be
• determines where they will go
• determines where they form
• determines the direction of the wind rotation

Pole regions receive less solar radiation than the equator, how does this affect global climate?

• The global climate is mostly cold.

• The global climate is mostly warm.

• Equatorial regions experience colder climates.

• Polar regions experience colder climates.

What is the result of convection currents in the atmosphere?

• UV Radiation

• Wind

• Humidity

• Ozone Layer

How would a person at the beach experience convection currents?

• They would feel the water as cold.

• They would feel the sand is hot.

• They would feel the heat of the Sun.

• They would feel wind as the air moves.

Convection currents from uneven heating of the Earth's surface cause _______.

• Fossils

• Volcanoes

• Mountains

• Wind
