FLASHCARD QUESTION
Front
Terawatt Noun
[ter-uh-wot]
Back
Terawatt
A unit of power equal to one trillion (10^12) joules per second, used to measure large-scale energy flow.
Example: This diagram shows how the flow of water in a hydroelectric dam spins a turbine and generator to produce electricity.

FLASHCARD QUESTION
Front
Conduction Noun
[kuhn-duhk-shuhn]
Back
Conduction
The transfer of heat through a material by direct molecular contact, without the bulk movement of the material itself.
Example: This diagram shows that heat conduction is the transfer of thermal energy between neighboring particles; high-energy particles collide with low-energy particles, passing heat along.

FLASHCARD QUESTION
Front
Convection Noun
[kuhn-vek-shuhn]
Back
Convection
The transfer of heat through the physical movement of fluids or other flowing materials, like gases, liquids, or the mantle.
Example: Heat from below causes water to become less dense and rise. As it cools at the surface, it becomes denser and sinks, creating a circular convection current.

FLASHCARD QUESTION
Front
Radiation Noun
[rey-dee-ey-shuhn]
Back
Radiation
The transfer of heat energy through space via electromagnetic waves, requiring no medium for its propagation.
Example: This diagram shows how the Sun sends heat energy to the Earth through space in the form of electromagnetic waves, which is called radiation.

FLASHCARD QUESTION
Front
Lithosphere Noun
[lith-oh-sfeer]
Back
Lithosphere
The cold, rigid outer layer of the Earth, comprising the crust and uppermost mantle, which is broken into tectonic plates.
Example: This map shows the Earth's lithosphere is not one solid piece, but is broken into large sections called tectonic plates that constantly move.

FLASHCARD QUESTION
Front
Thermal Conductivity Noun
[thur-muhl kon-duhk-tiv-i-tee]
Back
Thermal Conductivity
An intrinsic property of a material that quantifies its ability to transfer or conduct heat through it.
Example: This diagram shows how thermal conductivity works: high-energy particles in a hotter area collide with low-energy particles in a cooler area, transferring heat.
7.
FLASHCARD QUESTION
Front
Seismic Waves Noun
[sahyz-mik weyvs]
Back
Seismic Waves
Waves of energy that travel through Earth's layers, resulting from earthquakes, explosions, or volcanic activity.
Example: This diagram shows a cutaway of the Earth where an earthquake starts at the 'Focus'. The energy released travels outwards in all directions as 'Seismic Waves'.
