Currents 2

Why does warm air rise?

• Warm air is more dense than cooler air.
• Warm air has more pressure than cooler air.
• Warm air is less dense than cooler air.
• Warm air has a higher dew point than cooler air.

Air is warmer and less dense at the equator because the equator receives more____________________.

• wind

• solar radiation

• air pressure

• condensation

In the Northern Hemisphere, winds traveling north appear to curve east because of the:

• trade winds

• convection currents

• Coriolis effect

• polar easterlies

The Coriolis effect is the curving of wind across Earth. What causes winds to curve?

• Earth's revolution
• Earth's magnetic field
• Earth's rotation
• Earth's gravitational pull

Which best describes how winds in the jet stream blow?

• no pattern

• between a boundary of cold air and warm air

• between two boundaries of hot air

• between two boundaries of cold air

The Jet Stream helps weather systems come to NC by

• forcing winds to blow in the opposite direction.

• decreasing inland wind speed.

• moving air masses west to east across the United States.

• keeping temperatures consistently warm all year round

As altitude increases, the air pressure 

• decreases
• stays the same
• increases
• all of the above

Which of the following is the correct order of the atmosphere layers from Earth to space?

• troposphere, stratosphere, mesosphere, thermosphere, exosphere
• troposphere, mesosphere, thermosphere, exosphere, stratosphere
• thermosphere, stratosphere, mesosphere, troposphere, exosphere
• troposphere, stratosphere, mesosphere, exosphere, thermosphere
