As an expert in the field of Earth sciences, I'd like to delve into the intricate dynamics of energy sources that drive the Earth's system. The Earth, a complex and dynamic entity, is powered by a variety of energy sources both from within and beyond its boundaries. These energy sources are crucial for the functioning of the Earth's systems, including its climate, geology, and the sustenance of life.
The Sun, a colossal ball of hot plasma, is the most significant external source of energy for the Earth. It provides the light and heat necessary for photosynthesis, the process by which plants convert light into chemical energy, which is the foundation of life on Earth. Solar energy also drives the Earth's climate and weather patterns, as well as the water cycle, through the process of evaporation, condensation, and precipitation.
However, the Sun is not the only source of energy for our planet. The Earth also possesses internal sources of energy that are critical to its geological processes. One of these is the heat generated by the decay of radioactive isotopes within the Earth's mantle and crust. This natural radioactive decay releases heat as isotopes transform into more stable forms. This heat contributes to the convection currents in the mantle, which in turn drive the movement of tectonic plates.
Another internal source of energy is the gravitational energy that has been with the Earth since its formation. As the Earth coalesced from the solar nebula, the gravitational forces acting upon the accreting matter caused it to heat up. This primordial heat, combined with the heat from radioactive decay, is responsible for the Earth's internal dynamics, including volcanic activity and the creation of mountain ranges.
The interplay between these internal and external energy sources is what keeps the Earth's systems in motion. The external solar energy maintains the surface temperature conducive for life and drives the atmospheric and oceanic circulations, while the internal energy fuels the geological processes that shape the Earth's crust and contribute to its habitability.
In conclusion, the Earth's system is a marvel of natural engineering, with the Sun as the primary external energy source and the decay of radioactive isotopes and gravitational energy as the primary internal sources. These combined forces create the conditions necessary for the Earth to support a diverse range of ecosystems and life forms.

E12.9: Earth systems have internal and external sources of energy, both of which create heat. The Sun is the major external source of energy. Two primary sources of internal energy are the decay of radioactive isotopes and the gravitational energy from Earth's original formation.
