Which statement best describes heating by radiation?

• Air molecules touch the warm ground, heating them up.

• Sunlight travels through space without the aid of fluids or solids.

• Air at the equator rises and sinks at the poles.

Which statement best explains heating by convection?

• 
  

• Air molecules touch the warm ground, heating them up.

• Warm air rises and takes heat with it; eventually it cools and sinks.

• Sunlight travels through space without the aid of fluids or solids.

• Land and ocean absorb and re-emit heat from the sun.

In which direction does the moving force of air flow?

Which statement best describes how temperature, humidity, and pressure vary within an air mass?

• Temperature and humidity vary, but pressure does not.

• Temperature, humidity, and pressure are basically the same all through an air mass.

• Temperature at the border of an air mass is always higher than in the middle.

• Humidity makes the pressure in an air mass increase.
