EAPS 105: UNIT 4 - PLANETARY
HEATING & COOLING - LECTURE
QUESTIONS AND ANSWERS
What happens when an object a moving object hits something and is suddenly
stopped? - Correct Answers -- It deforms
- Its atoms vibrate faster
- It heats up
What is meant by primordial heating? - Correct Answers -Heating that only occurs
during planet formation
What is the source of heating from radioactive decay? - Correct Answers -Collisions of
emitted particles
What is the only means by which a body can shed its heat to space? - Correct Answers
-Radiative heat transfer
Which of the following processes might a single plate planet still experience? - Correct
Answers -Mantle convection
What is a consequence of the cooling of the interiors of Mercury and the Moon? -
Correct Answers -Thrust faulting on their surfaces
What is a consequence of the cooling of Pluto's subsurface ocean? - Correct Answers -
Normal faulting on its surface
How does convection transfer heat? - Correct Answers -Through the motion of buoyant
volumes
The Earth's mantle is a solid (its temperature is less than its melting temperature). How
does it transfer heat from the core toward the surface? - Correct Answers -Convection
What do you call the strong outer layer of a planet, containing both crust and cold
uppermost mantle, that comprises a tectonic plate? - Correct Answers -The lithosphere
What do you call the warm, weak region that flows like a viscous fluid and enables
tectonic plates to be mobile? - Correct Answers -The asthenosphere
