Electromagnetic radiation is the primary energy source on Earth and the driver of the entire climate system.
The sun is also the source of energy that drives all life on Earth. This energy controls the weather, ocean currents and the hydrological cycle, influences our mood and daily activities.
The sun is a star, the same as the stars we see in the night sky, it is only much, much closer to us. It is nearly 150 million kilometers away from Earth. It is at the heart of our solar system and warms our planet enough that life can thrive on it. For over 4.5 billion years, this hot-ball of glowing plasma has been the engine of time, climate and life on Earth.
The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.
