Multiple Choice

An unequal heating of the surface of Earth by the sun causes areas of high and low pressure to form. What do the arrows in the diagram most likely represent?

• wind
• precipitation
• clouds
• runoff

Multiple Choice

The Sun heats the atmosphere of Earth unevenly. Which of the following statements is the most likely result of this uneven heating?

• Convection in the atmosphere causes a change in air density, resulting in winds.

• Conduction through the atmosphere causes evaporation to occur over oceans, resulting in rain.

• Radiation from the Sun reflects through the atmosphere back into space resulting in cooler evenings.

• Radiation from the Sun causes atmospheric moisture to collect over mountain ranges resulting in snowfall.

Multiple Choice

What is humidity?
