The sun
The two main sources of Earth's internal heat energy are residual heat from the planet's formation over 4.6 billion years ago and the decay of radioactive isotopes within the Earth's mantle. The heat generated by these processes contributes to the movement of tectonic plates and drives geological activity on the planet.
The Earth's principal sources of internal energy are radioactive decay of elements in the Earth's core and residual heat from the planet's formation. External energy sources include solar radiation, which drives processes like weather patterns, ocean currents, and ecosystems. Together, these energy sources contribute to the dynamic processes shaping Earth's geology and climate.
The two main energy sources for Earth's system are solar energy from the sun, which drives processes like photosynthesis and weather patterns, and geothermal energy from Earth's internal heat, which powers processes like plate tectonics and volcanic activity.
When we speak of global warming, we usually mean the recent increase in average global temperatures. The two gases considered to be the major contributors to this effect are carbon dioxide and methane.
Two sources that contributed to Earth's hydrosphere are outgassing from volcanic activity, which released water vapor that later condensed to form oceans, and cometary impacts during the early formation of the planet, bringing water-rich materials to Earth.
The Earth system is powered by energy from two major sources: the Sun and the planet's internal heat.

Oceans are the greatest sources.

The five sources of background radiation are cosmic radiation from outer space, terrestrial radiation from the Earth's crust and building materials, radon gas from soil and rocks, internal radiation from within our bodies, and medical sources like X-rays.
