Mini-Quiz: Infrared, Gases and the Greenhouse Effect

by Ron Kurtus

Take this Mini-Quiz to check your understanding of the lesson material.

1. What does carbon dioxide in the atmosphere do?

It absorbs harmful ultraviolet rays, thus protecting the planet

It absorbs infrared radiation, thus heating the air

It reflects infrared radiation back to the Earth

2. What can happen when there is an excess of CO2 and CH4 in the atmosphere?

The amount of sunlight absorbed and changed to heat goes above 70%

The amount of sunlight absorbed and changed to heat goes below 30%

The amount of sunlight reflected back into space becomes 100%

3. Why are there more violent storms with increased temperatures?

Higher temperatures actually reduce the energy of storms

Higher temperatures mean greater kinetic energy in the air

Higher temperatures increase the carbon oxide in the storms

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.

This is the only Earth we have
