Convection & Wind: Video Quiz

Why is wind invisible?

• Because it moves too fast to see

• Because it is made of air molecules, which are too small to see

• Because it is a man-made concept

• Because it only occurs at night

What gives wind its mass?

• Sound waves

• Dust particles

• Air molecules

• Water vapor

What causes the wind to change its strength?

• The amount of sunlight

• Changes in air pressure

• The rotation of the Earth

• Ocean currents

What factors make air more or less dense?

• Forest density, urban development, and snow cover

• Temperature, height above sea level, and water vapor

• Soil moisture, air pollution, and cloud cover

• Ocean depth, latitude, and longitude

What happens when air gets warmer and rises?

• It has no effect on air pressure.

• It decreases air pressure.

• It increases air pressure.

• It solidifies into clouds.

How do convection cells form?

• By the gravitational pull of the moon on the Earth's atmosphere

• Through the evaporation and condensation of water

• Due to the rotation of the Earth on its axis

• By air moving in patterns due to temperature differences
