4. Conduction.
5. Convection.
6. Radiation.
7. Tectonic plates.
8. Thermal energy.
9. Thermal energy through conduction.
10. Subduction zone.
Explanation:
1. Core in the interior of the earth can be classified as primordial and radiogenic heat.
2. The thermal energy released as a result of spontaneous nuclear disintegration, is called Radiogenic Heat while the internal heat energy accumulated by dissipation, in a planet during its few million years of evolution is called Primordial heat.
3. There are three processes that can be used to transfer heat, conduction, convection and radiation.
4. Conduction governs the thermal conditions in almost entire solid portions of the Earth and plays a very important role in the lithosphere.
5. Convection 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.
6 Radiation is the least important mode of heat transport in the Earth.
7. Convection current is relevant to the movement of tectonic plates, because the heat builds up pressure underneath the crust.
8. The thermal energy 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 thermal energy through conduction.
10. The area where subduction occur is called subduction zone. It is a zone which represents the collision between the two (2) tectonic plates of planet earth. Subduction zone occurs in countries such as Japan, Canada, Indonesia, Russia, Alaska, and around the Pacific Ocean.
Generally, subduction zones are responsible for high intensity earthquakes, volcanoes and tsunamis around the world.
