which energy source cause our weather?

The sun. Because the earth's surface is not uniform, oceans, mountains, plains for example, the sun heats it unevenly and this causes all the weather. If the earth was all ocean there would still be weather but it would be even and predictable with places of constant rain and areas of no rain.

Mostly the sun.

All

Here is something you likely will not hear anyplace else: a significant cause of weather is the northern lights. If you study the jet stream you will find that it goes all the way around the world and it keeps going all the time. If weather were only powered by the sun, the jet stream would be more of a tide than a stream.

The northern lights are powered by an electric current. When the current interacts with the Earth's magnetic field it creates what we call a Faraday motor in the air.

It is the sun. A week ago, I was flying my little aircraft from the north of Germany to Norway where I live and it was very turbulent; I was shaking in all directions. That was because the sun was heating the earth that, in turn, heats a layer of air above it. As this air rises, it makes it turbulent. Perhaps not so much perceptive from an airliner but surely from an tiny aircraft like mine.

Then I was thinking: Wow, what an amount of energy, even here, up north! My airplane is about 500 kilos and it is shaken in all direction simply from the energy of the sun that is absorbed then released by the ground under me!

Amazing, isn't it? All of our energy, except for geothermal energy like the one used in Iceland, comes from the sun. The wind, the temperature and even the tide! Well, for the tide, it is about 60 percent the moon but also about 30 percent the gravitational pull of the sun.

gravitation is the root reason.bcoz earth revolves around sun bcoz of gravitation.
