Sunlight and water are 2 examples of renewable sources because they will never run out.
the sun is the main source of energy for earth but indirectly as by solar energy the plants do photosynthesis which powers the planet earth . you may find detailed info in the book "eating the sun by oliver morton"
2. To identify the changing patterns of the ore deposits of the early Earth.
I assume you mean the heat in Earth's interior. This heat comes from three sources. (1) Heat left over from when the Earth formed. This part should be quite insignificant, since Earth has had enough time to cool down. (2) Decay of radioactive isotopes. (3) The fact that the liquid part of the Earth is gradually solidifying also generates heat.
Nitrogen and Oxygen account for almost 99% of Earth's atmosphere.
The two sources of energy are the sun and energy from the Earth's Interior.

What were the 2 sources of energy suggested by oparin theory
It depends on whether you mean all of the other energy sources on the earth or all of the other energy sources throughout a larger area (i.e., the solar system, galaxy, supercluster, universe). If the former, then yes. According Einstein's E=Mc^2 equation, the sun produces 4 x 10^33 ergs/sec of energy. In one second, the sun has produced vast amounts more of energy than all other energy sources on earth for a day.
The Blue Nile and the White Nile are the two main sources of the Nile River.

The two main sources of air pollution are the toxins released from factories and automobiles.
The Sun is at a distance of about 150 million kilometers from Earth. It has a diameter of 1.4 million kilometers. Its apparent diameter (as seen from Earth) is about 1/2 of a degree. It is the main source of energy for Earth. It gets its energy from nuclear fusion - converting hydrogen-1 into helium-4. It has about 99.86% of the mass of the entire Solar System.
