Weather Factors Part 2

1. Electromagnetic waves are classified by

Color

Speed

Wavelength

Visibility

2. The Celsius temperature scale is used

Only in America

By scientists to describe temperature

By weathermen to describe weather reports

Very rarely

3. Air temperature is usually measured with a (n)

Thermometer

Aneroid Barometer

Mercury Barometer

Psychrometer

4. The Earth’s surface is heated mainly by

Radiation

Convection

Conduction

Evaporation

5. Infrared radiation is felt in the form of

Heat

Light

Sound

Convection waves

6. In which state of matter are the molecules moving at a faster speed?

Solid

Liquid

Gas

They all move at the same speed

7. The formula for temperature conversion is ^oC = 5/9 (^oF – 32). 50^oF is converted to which of the following Celsius temperatures.

10 degrees Celsius

20 degrees Celsius

30 degrees Celsius

40 degrees Celsius

8. Energy from the sun travels to the Earth’s surface by

Evaporation

Conduction

Convection

Electromagnetic Waves

9. The direct transfer of heat from one substance to another through contact is called

Infrared radiation

Convection

Conduction

Ultraviolet radiation

10. Which of the following colors has the longer wavelength?

Red

Orange

Green

Blue

11. Radiation, conduction and convection heat which layer of the Earth’s atmosphere?

Stratosphere

Mesosphere

Ionosphere

Thermosphere

12. Sunsets and sunrises are red because

Light from the sun is scattered leaving only red and blue light

Light from the sun is scattered leaving only red and orange light

The sun is higher in the sky

Heat in the atmosphere diffuses the light leaving red and orange light.

13. The transfer of heat by the movement of fluid or gas is

Radiation

Conduction

Convection

Evaporation

14. The difference between temperature and thermal energy is

Temperature deals with the number of particles and thermal energy deals with heat output.

Temperature deals with heat output and thermal energy deals with the number of particles.

Temperature goes from higher to lower concentration while thermal energy goes from lower to higher concentration.

Temperature goes from lower to higher concentration while thermal energy goes from higher to lower concentration.

15. Most of the energy from the sun travels to Earth in the form of

Ultraviolet radiation

Electromagnetic radiation

Visible light

Convection waves

16. What percentage of the Sun’s energy is reflected by clouds, dust and gasses?

5%

20%

25%

50%

17. What percentage of the Sun’s energy is absorbed by the Earth’s surface (land and water)?

5%

20%

25%

50%

18. Which of the following colors has a higher frequency

Red

Orange

Green

Blue

19. What percentage of the Sun’s energy is reflected back into the Earth’s atmosphere by the surface of the Earth?

5%

20%
