6.E.2.1 Earth's Structure Test Review

The core has the highest temperature of all the layers of Earth. Which

statement best supports this observation?

• The core is farthest from the sun, so it must generate its own heat.

• The core is closest to the sun, so it is warmed by fusion events in the

  solar atmosphere.

• The core is farthest from the center of Earth, so it receives more heat

  from direct sunlight.

• The core is closest to the center of Earth, so it is warmed by the

  frictional heating of dense metals.

Which statement best describes what has happened to Earth’s crust over

time?

• The crust has cooled to form solid nickel and iron.

• The crust has changed position because of Earth’s magnetic field.

• The crust has been broken into pieces that move over molten rock.

• The crust has heated up because of its position near the Earth’s

  molten inner core.
