23.

Multiple Choice

30 sec

1 pt

What causes storm clouds to form?

evaporation of surface water from ground conduction

low air pressure allows water vapor to rise

water vapor cools as it rises and condenses on particles in the air

all of the above

24.

Multiple Choice

1 pt

Where does rain usually occur?

Low-pressure areas where air is warmer, less dense and contain more water vapor

low pressure areas where air is cooler and denser

high pressure areas where air is warmer, less dense and contain more water vapor

high pressure areas where air is cooler, denser with less clouds

Which are true about sunlight (thus thermal) intensity differences in different areas on earth. Check all that apply

Shape of earth and axial tilt causes light to be more spread out at poles

sun hits more directly with more intensity at the equator

more direct and intense sunlight means colder temperaures

The equator has more variation in temperature then the different hemispheres
