What I Have Learned
1.
Read each question and fill in the blanks with the correct term to complete the
statement. Write your answer on a separate sheet of paper.
in the interior of the earth can be classified as primordial
and radiogenic heat.
2. The thermal energy released as a result of spontaneous
is called
Radiogenic Heat while the internal heat energy accumulated by
in a planet during its few million years of evolution is called Primordial heat.
3. There are three processes can transfer heat:
and
radiation
4.
5.
governs the thermal conditions in almost entire solid portions of
the Earth and plays a very important role in the lithosphere.
involves transfer of heat by the movement of mass, which is a
more efficient means of heat transport in the Earth compared to pure
conduction
is the least important mode of heat transport in the Earth.
6.
7. Convection current is relevant to the movement of
because the heat builds up pressure underneath the crust.
8. The
of the core is transferred to the surface of the earth
and the lower levels of ocean by conduction
9. Air molecules come in contact with the warmer surface of the land or ocean,
resulting to the increase of its
10. The area where subduction occur is called
