Multiple Choice

Which property of the air is MOST DIRECTLY responsible for the formation of convection currents?

• chemical composition

• cohesion and adhesion of water vapor

• density differences

• specific heat

• wind

Multiple Choice

Why do areas near the equator receive more direct solar radiation than areas near the poles?

• Because the sun's rays hit the equator at a more direct angle

• Because the equator is closer to the sun

• The earth's rotation only

• The sun's gravity

• Mountains blocking air movement

Multiple Choice

What happens to wind speed when the difference in air pressure increases?

• The wind blows faster

• The wind stops blowing

• The wind blows slower

• The wind changes direction

Multiple Choice

Which of the following statements about warm fronts is correct?

• Warm fronts move slower than cold fronts.

• Warm fronts bring heavy storms and rain.

• Warm fronts are symbolized by blue triangles.

• Warm fronts occur when cold air replaces warm air.

Multiple Select

Select ALL the correct characteristics of a stationary front.

• Can occur when a warm or cold front stops moving

• Tends to produce cloudy skies and precipitation

• Moves rapidly across regions

• Winds blowing parallel encourage the front to stay in place

Multiple Choice

Multiple Choice

A occluded front is represented by ______________.

Multiple Choice

What is the main difference between weather and climate?
