Exposure from terrestrial radiation. The composition of the earth's crust is a major source of natural radiation. The main contributors are natural deposits of uranium, potassium and thorium which, in the process of natural decay, will release small amounts of ionizing radiation.-rays: X-rays are a form of radiation similar to gamma radiation but they are produced mainly by artificial means rather than from radioactive substances. Neutron radiation: Neutron radiation occurs when neutrons are ejected from the nucleus by nuclear fission and other processes.
The sun is the major source of energy for the Earth system. Heat from Earthâs interior also supplies energy, but the amount of energy is much smaller. Energy from the sun and from Earthâs interior moves through the geosphere, hydrosphere, biosphere, and atmosphere.hat You Will Learn â¢ Heat flow is the transfer of energy from a warmer object to a cooler object. â¢ Energy from the sun, the major source of energy for phenomena on Earthâs surface, is transmitted to Earth by radiation.
