Answer:

B) (1) Heat of accretion; (2) heat from convection; (3) heat from thermal radiation.

Explanation:

  • Accretion is a process of the planet being formed by bits of rock and iron that are clumped together. Hence larger the planet larger the heating.
  • The heat from the convection currents in the atmospheric circulation and the heat derived from the thermal radiation of the earth.
  • This depends on the shape, size and nature of the surface of the earth. All this balances the heat flow within the terrestrial earth.
