WebThe internal heat of the earth comes from several sources. It is claimed that it comes from compression due to gravity. In point of fact some of the heat comes from that but it is trivial in amount. The core or near the core of the earth contains a nuclear reactor. WebThe global heat budget is the balance between incoming and outgoing solar radiation. Incoming solar energy varies at different times of year and for different locations across …

WebThe balance of incoming and outgoing energy and the passage of the energy through the climate system is Earth's energy budget. When the incoming energy is greater than the outgoing energy, Earth's energy budget is positive and the climate system is warming. If more energy goes out, the energy budget is negative and Earth experiences cooling. WebThe source of Earth's internal heat is attributed mainly to (a) residual heat from gravitational energy left over from planetary accretion, differentiation, and formation of the core, and (b) the decay of radiogenic isotopes, specifically, 238 …

Websun’s radiation that enters Earth’s atmosphere must eventually be sent back to space. This is achieved through Earth’s energy balance.
