1.
How does energy from the Sun travel to Earth?
a)
Most of the energy from the sun travels to Earth in the form of visible light and infrared radiation. A smaller amount arrives as ultraviolet radiation.
b)
wavelengths longer than red light; not visible, can be felt as heat
c)
Some sunlight is absorbed or reflected by the atmosphere before it can reach the surface. The rest passes through the atmosphere to the surface.
d)
water vapor and carbon dioxide in the mesosphere/stratosphere
2.
What is visible light?
a)
wavelengths longer than red light; not visible, can be felt as heat
b)
wavelengths shorter than violet light; not visible, can cause sunburns
c)
All of the colors of the rainbow
d)
the ozone layer in the stratosphere
3.
What is infrared radiation?
a)
All of the colors of the rainbow
b)
wavelengths longer than red light; not visible, can be felt as heat
c)
water vapor and carbon dioxide in the mesosphere/stratosphere
d)
wavelengths shorter than violet light; not visible, can cause sunburns
4.
What happens to the Sun's energy when it reaches Earth?
a)
Clouds reflect sunlight back to space.
b)
Short wavelengths scatter more than long wavelengths. Blue and violet light are the longest visible wavelengths. That is why the sky is blue.
c)
When the sun's energy is absorbed by the atmosphere and the gases in the atmosphere hold the heat
d)
Some sunlight is absorbed or reflected by the atmosphere before it can reach the surface. The rest passes through the atmosphere to the surface.
5.
How and where is ultraviolet radiation absorbed in the atmosphere?
a)
water vapor and carbon dioxide in the mesosphere/stratosphere
b)
the ozone layer in the stratosphere
c)
it is not absorbed
d)
when particles and gases disperse light in all directions
6.
What is scattering?
a)
When you drop something and it scatters everywhere
b)
When the sun's energy is absorbed by the atmosphere and the gases in the atmosphere hold the heat
c)
Air temperature is usually measured with a thermometer.
d)
when particles and gases disperse light in all directions
7.
Why is the sky blue?
a)
50%
b)
When the sun's energy is absorbed by the atmosphere and the gases in the atmosphere hold the heat
c)
Short wavelengths scatter more than long wavelengths. Blue and violet light are the longest visible wavelengths. That is why the sky is blue.
d)
the total energy of motion in the particles of a substance
8.
How much of the sun's energy is absorbed by land and water?
a)
50%
b)
5-10%
c)
80-90%
d)
15-20%
9.
How much sunlight is reflected by clouds, dust, and gases?
a)
25%
b)
50%
c)
20%
d)
5%
10.
How much sunlight is absorbed by Earth's surface?
a)
50%
b)
20%
c)
5%
d)
17%
11.
What is thermal energy?
a)
the average amount of energy of motion of each particle of a substance
b)
the total energy of motion in the particles of a substance
c)
Heat is transferred in three ways: convection, conduction, and radiation.
d)
the transfer of heat by movement of fluid
12.
What are the freezing and boiling points in Celsius?
a)
0 degrees and 100 degrees
b)
32 degrees and 212 degrees
13.
What is convection?
a)
the direct transfer of energy by electromagnetic waves
b)
the transfer of heat between two substances in direct contact
c)
the transfer of heat by movement of fluid
14.
What is radiation?
a)
the transfer of heat between two substances in direct contact
b)
the direct transfer of energy by electromagnetic waves
