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? - ✔ ✔ Convection What do you call the
location where an ocean plate dives back into the interior of the
Earth? - ✔ ✔ A subduction zone
What do you call the location where new oceanic plates are
create? - ✔ ✔ A mid-ocean ridge
What do you call the strong outer layer of a planet, containing both
crust and cold uppermost mantle, that comprises a tectonic plate?
- ✔ ✔ The lithosphere
What do you call the warm, weak region that flows like a viscous
fluid and enables tectonic plates to be mobile? - ✔ ✔ The
asthenosphere
What happens when an object a moving object hits something and
is suddenly stopped? - ✔ ✔ All the above

- ✔ ✔ Normal faulting on its surface
What is a consequence of the cooling of the interiors of Mercury
and the Moon? - ✔ ✔ Thrust faulting on their surfaces
, What is meant by primordial heating? - ✔ ✔ Heating that only
occurs during planet formation
What is the only means by which a body can shed its heat to
space? - ✔ ✔ Radiative heat transfer
