Which does not affect the formation of land mass

like volcano and mountain during the convection in Earth’s mantle?

• Heat tries to escape in the interior of the earth

• Collision and separation of tectonic plates happen due to the slow

  motion of convection cells.

• When warm material in the mantle rises to the surface (ground), it will

  cool and sinks, these cooled materials will eventually be turned into

  landmass

• Spontaneous nuclear disintegration of radioactive elements

  produced thermal energy.
