2. How does the conduction in the surface of the earth affect the temperature of
our atmosphere?
A. Air molecules come in contact with the warmer surface of the land and ocean resulting to the increase of its thermal energy.
B. Air molecules come in contact with the cooler surface of the land and
ocean resulting to the decrease of its thermal energy.
C. Air molecules does not come in contact with the warmer surface of the
land and ocean resulting to the increase of its thermal energy.

3. How does convection in Earth’s mantle affects the formation of landmass like
volcano and mountain?
A. Heat tries to escape in the interior of the earth.
B. Collision and separation of tectonic plates happens due to the slow
motion of convection cells.

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