Electromagnetic Spectrum
What is the range of all types of light energy produced by the Sun called?
Electromagnetic Spectrum
What is Earth's energy budget?
The balance of incoming solar energy and outgoing energy.
Name one of the gases that is a significant cause of the greenhouse effect?
Carbon Dioxide, Methane, Water Vapor
What are the three main ways heat is transferred?
Radiation, Conduction, Convection
What is energy transformation?
Transforming from one form to another
Name two types of electromagnetic waves produced by the Sun.
Infrared, Ultraviolet, Visible Light
Name the primary source of energy that contributes to the Earth's energy budget.
The Sun
Describe how the greenhouse effect works in simple terms.
"Traps heat"
Define conduction.
Describe how sunlight can be transformed into a chemical energy process
Photosynthesis
What part of the electromagnetic spectrum can be seen by the human eye?
Visible Light
What percentage of solar energy is reflected back into space?
25%-30%
Why is the greenhouse effect important for life on Earth?
Helps regulate temperature
How does convection work in the atmosphere?
Hot air rises, cold air falls/sinks.
Describe the energy transformation involved with gasoline and a car.
Chemical to Mechanical
How does ultraviolet light from the Sun affect living things on Earth?
Skin cancer, Eye damage, sun burn
What on Earth's surface absorbs the sun's energy?
Land & Water.
What human activities can increase the greenhouse effect?
Deforestation, Air pollution, Carbon Emissions, Burning fossil fuels, etc.
Give an example of radiation in everyday life.
Sun, etc.
Describe the energy transformation involved with a flashlight
Chemical to Electrical to Radiant
Provide an example of gamma rays used in everyday life.
Treating cancer
Approximately how much energy is radiated back out into space from the atmosphere?
64%
Explain how the greenhouse effect can lead to global warming.
It heats up the planet. Planet becomes hotter, etc.
Explain how heat transfer affects ocean currents.
Heat transfer by convection, warm water currents distribute heat globally as they move.
What object uses an energy transformation of electrical energy to Radiant/Light & Sound energy?
TV
