Heat Transfer
What is heat transfer?
Heat transfer is the movement of thermal energy from a warmer object to a cooler object.
What is the greenhouse effect?
It is the process where gases in the atmosphere trap heat from the Sun.
Define Electromagnetic Waves.
A form of energy that can move through the vacuum of space.
What is the lowest layer of Earth’s atmosphere?
The troposphere.
What is the most abundant gas in Earth’s atmosphere?
Nitrogen
What are the three types of heat transfer?
Conduction, convection, and radiation.
What are greenhouse gases?
carbon dioxide and methane.
Define Absorbed.
Having your attention completely on something or something soaked up
Which layer contains the ozone layer?
The stratosphere.
What gas do humans need to breathe?
Oxygen.
What is conduction?
Conduction is the transfer of heat through direct contact between objects.
Why is the greenhouse effect important?
It keeps Earth warm enough for life to exist.
Define the greenhouse effect.
Gases in the atmosphere that trap some of the heat near Earth's surface while letting some heat escape
Which layer is where most meteors burn up?
The mesosphere
What percentage of the atmosphere is oxygen?
21%
What is convection?
Convection is the transfer of heat through the movement of fluids, such as liquids and gases.
What can cause the greenhouse effect to become stronger?
Increased amounts of greenhouse gases from activities like burning fossil fuels.
Define Thermal Energy.
Is the total energy of motion in the particles of a substance
Which layer is known for very high temperatures
What gas do plants use during photosynthesis?
Carbon dioxide (CO₂).
What is radiation?
Radiation is the transfer of heat through electromagnetic waves, like heat from the Sun.
What happens when too much heat is trapped in the atmosphere?
Earth’s average temperature increases, contributing to climate change.
Define Radiation.
The energy that is transferred from the sun to earth
What is the outermost layer of the atmosphere?
The exosphere
Why is the atmosphere important to Earth?
It provides gases needed for life and helps protect Earth and regulate its temperature.
