Earth has internal energy due to radioactivity. I am not sure what you mean by radioactive external energy, or simply by external energy. Earth gets most of its energy from the Sun.
Sunlight is the main source of energy on earth
Yes. Most of Earth's energy comes from the Sun.
Sun sends heat energy to earth.
where does the radient energy transmitted to earth come from
Yes.
they dont they give oxygen
Radioactive and solar energy (or light and heat).
Gravitational energy
The energy of the sun is produced by the process of nuclear fusion, and a portion of this energy reaches the Earth in the form of sunlight, which heats the Earth.
The light travel directly through the vacuum and reaches earth
it gives us energy beacause the energy come directly from the sun which comes towards the earth.
they give us energy to survive
The sun gives energy, in the form of heat and light.
The Sun is a huge star that is seen during the day on Earth. It gives the Earth many things, it give energy, vitamins, heat and helps things live.
To conserve energy and give mother earth a break
The sun radiates energy cased by the nuclear fusion of Hydrogen into Helium. Clarify the rest of your question please.
