Electromagnetic Spectrum
Which type of wave can we see?
Visible Light
Where does the Earth get most of its energy?
The Sun
What do we compare the atmosphere to since it traps heat?
A Blanket
What is the transfer of heat through direct contact?
Conduction
What type of energy is stored in food?
Chemical
Which types of waves are on either side of visible light on the spectrum?
Infrared and Ultraviolet
How much of the Sun's energy is absorbed by the Earth?
50%
What is the most common greenhouse gas?
Carbon Dioxide
When heat travels in waves, what is that known as?
Radiation
What type of energy is used to power devices? (Chromebooks, Phones, etc.)
Electrical Energy
Which two waves can transmit information across long distances?
Radio and Microwaves.
What does the Earth do with the energy it absorbs at the surface?
Powers the water cycle, drives ocean currents, and photosynthesis, etc. (Teacher's Discretion)
What could happen if the greenhouse effect is too strong?
The average temperature on Earth would be higher.
What is the process called where a warm substance rises and a cool substance sinks?
Convection
Give one example of turning mechanical energy into electrical energy?
Windmills, Hand-Crank Flashlight, etc.
Which two waves are the shortest types of waves on the electromagnetic spectrum?
X-Ray and Gamma Rays
How much energy is radiated back out into space?
64%
How does the greenhouse effect trap heat?
Shortwave radiation can travel through but longwave radiation is blocked
Which two areas of our Earth experience convection?
Oceans and the Atmosphere
How can we turn solar energy into electrical energy?
Solar panels absorb light and turn that energy into electricity through conduction cells in the solar panels
Name one device that uses a wave from the electromagnetic spectrum (Microwave/Visible Light excluded)
Radio (Car Radio), Infrared (Thermal imaging), Ultraviolet (Black Lights), X-Ray (MRI Machine), Gamma Ray (Chemotherapy), (Teacher Discretion)
What is the energy in the atmosphere used for?
Driving weather patterns
What could happen if the average temperature increases?
Increase in severe weather, melting polar ice caps, and flooding in coastal cities
What do convection cells in the oceans cause?
Convection cells in the oceans drive ocean currents
Give one example of a three-step emergy transformation.
Flipping a light switch, A glowstick, etc.
