Planets' sources of energy?

Question

What are the sources of energy for the following planets/moons:

Mercury
Venus
Earth
Luna (Earth's moon)
Mars
Asteroid Belt
Jupiter
Europa
Io
Saturn
Titan
Uranus
Neptune
Pluto
Comet Cloud


The choices are: Either it is Sun or Volcanoes ( That can be on the planet's moons)

Thank you for your time. I hope that I will get the answer to this question...

And all of them have their own answer. What I mean is that some of the answers are SURELY "volcanoes" and others are SURELY "the sun."
Still, thank you.

Answer 1

mercury would be the sun.

venus would most ly be the sun with a bit from itself.

earth mostly the sun, bit from interior.

mars, sun its interior is cold now.

jupiter is itself. it gives off more radiaiton than it gets from the sun, and the miniscule volcanoes on io don't affect jupiter at all.

saturn, uranus and neptune would be the same way but to a lesser extent since they are smaller.

pluto would have to be the sun since it should be frozen solid.

io's source would be its interior which is kept hot from graviational interactions with jupiter, likewise with europa.

comet cloud? the oort cloud? i guess the sun. those distant comets don't have much energy though. until they get closer to the sun.

Answer 2

There are three main sources of energy: The sun, internal heat, and tidal interaction. The weather on planets is mostly driven by the sun. Tectonics (volcanos, continental drift) is usually driven by internal heat. The volcanos on Io get their energy from tital interaction with Jupiter. They also think Europa has underwater volcanos powered by tidal forces. Tidal forces also power the earth's ocean tides of course. Jupiter generates more energy by internal heat than it recieves from the sun. I don't know if Saturn, Uranus, and Neptune do also. For everything else, I think sunlight is the primary source of energy.

Answer 3

Planets have other sources of energy besides volcanos and the Sun. The Earth, for instance, is heated internally by radiactive decay.

Answer 4

All objects in the universe acquired their energy by motion or by heating, all these planets spin or revolve, these movement in effect spanned of the weight inside its body since the weight of an object is naturally trap inside the body, this why any object no matter how big they are, it floats. The spanned off weight naturally returns to the body
that creates pressure to the surface on an object thereby drags it to the surface, the force we know as gravity. Volcanoes are just effect of tremendous weight traps inside the body creating pressure and heat from within but not the source of energy of its host, is the weight and pressure of the body released during movement (the force we commonly describe as inertia, which is actually the source of all other energy, The spontaneous sun thermo nuclear activity is created by the pressure of weight exerted by the planets during revolution, in return, Heating enable the sun to throw weight and pressure to all object in the solar system as an energy. Electron and proton particle essential for pro-creation's.

Hope this will partially answer your question since to give you all the details of how the sun or the star was created by this energy will require us time.

Answer 5

Obviously the sun. Not all the planets have volcanos, or even a surface.

Answer 6

The sun and internal heat. I think I read that Jupiter is the only planet that puts out more heat than it receives. Jupiter is almost a brown star - massive, but not massive enough and made of the right chemicals.

Answer 7

Easy one, it's the Sun.
