the sun gives off energy
The energy that reaches the Earth from the sun is known as sunlight.
The sun, like all stars, gets its energy from nuclear fusion. The Earth is only habitable for life because of the sun's radiant energy which reaches us. So we all depend on nuclear energy.
absorbed by earth's core
Electromagnetic radiation.
It turns to solar energy.

The Sun produces its energy - the heat and light that reaches us from the Sun - from nuclear fusion. Specifically, it converts hydrogen to helium.

Nearly all of the energy that reaches Earth's surface comes from the sun.

Mainly through radiation (electromagnetic waves, especially light).
