(Don't type in Caps Lock)

Which of the following is NOT a major process that has contributed to Earth’s

internal heat?

• Heat from the sun since the beginning of Earth history.

• Heat released as iron crystallized to form the inner core.

• Heat from radioactivity of radioactive isotopes of U, Th and K.

type of heat transfer?

Which does not play a very important role of radioactive decay in earth’s internal

heat?

• When radioactive element decays, it produces heat.

• Radioactive element can be found anywhere in the planet.

• Spontaneous nuclear disintegration of radioactive elements

  produced thermal energy.

• Heat released by colliding particles during the formation of the

  Earth.
