Explain how the kinetic molecular theory describes the behavior of gas particles.

• Gas particles are in constant, random motion and collide elastically.

• Gas particles are stationary and vibrate in place.

• Gas particles move in a fixed pattern.

• Gas particles are attracted to each other strongly.

What is the effect of the greenhouse gases on Earth's temperature?

• They cool the Earth by reflecting sunlight.

• They have no effect on Earth's temperature.

• They warm the Earth by trapping heat.

• They cause the Earth to freeze.
