Asked in Energy
What do you understand by energy flows in a one way direction but water follows in a cycle pathway in the living world?
Energy is continuously being degraded - converted from useful energy to less useful energy. We get our energy from the Sun, which burns its nuclear fuel (hydrogen), and radiates the energy into space. The energy Earth receives will again be radiated into space, sooner or later. From there it gets diluted; most of it won't ever return to the Sun. ...
Asked in Planetary Science
How long will it take the get the suns heat to earth?
It will take 8 minutes for the light from the sun to reach Earth. The actual heat of the sun does not reach all the way out to Earth. The warmth on Earth comes from the conversion of light energy to heat energy. ...
Asked in Physics, Solar Power
Why do you say that solor energy is one way traffic?
Energy comes from Sun to Earth (and is also radiated into space in general). No significant amount of energy gets back into the Sun. That means that the Sun continuously loses energy. ...
Asked in Seasons
Why does the earth get more energy from the sun in summer compared to winter?
well because we are not turned to the sun all the way in winter and we are turned all the way in summer ...
Asked in Nuclear Energy, The Sun
Does Nuclear power plants on Earth create energy in the same way as the Sun?
No, nuclear power plants get their energy from fission of the heavy element uranium, the sun gets its energy from fusion of the light element hydrogen. ...
Asked in Energy
Does energy leave the ecosystem in the form of heat?
If by the 'ecosystem' you mean the surface of the earth and its atmosphere, which includes all living things on earth, then yes, the only way for energy to leave is by radiation out into space. The ecosystem receives heat from the sun and from the earth's hot interior, and radiates heat back into space, thus maintaining a thermal balance over time. ...
Asked in Earth Sciences
Does most of the Sun's energy make it to the Earth's surface?
No, the Sun is a spherical star and it radiates it energy in all directions from all of its surface, this amounts to 384.6 yotta watts (3.846×1026 W)per second. The earth is VERY small and quite a long way from the Sun and only receives 84 Terrawatts of Power per day over its entire surface, a very small fraction of what the Sun is producing. ...
Asked in Solar Power
What ways do people use sun's energy?
If you stand in the sun it gives you vitamin C, and also another way is to use the sun is by using it to power solar powered electricity. The sun generates all energy we have on earth. Plants use sunlight for photosynthesis and the cycle goes from there. Also the sun heats the earth. ...
Asked in Science
How the tomato plant can be traced back to the sun?
The most obvious answer is that Tomato plants have to photosynthesise using in part energy from the sun. If they did not have this energy from the sun and photosynthesis the plant would not be able to grow. Another way a tomato plant can be traced back to the sun is that when the earth was created it was essentially spat out by the sun. In this way all tomato plants are made of matter that was once part of the...
Asked in Solar Power
Can the sun burn out because of the over use of Solar Power?
No. The sun gives out enormous amounts of energy whether we use it or not. Of that energy, only a tiny percentage makes its way to Earth and we only need a small portion of the energy that reaches Earth for solar power. In other words, the use of solar power does not affect the sun in any way. The sun will eventually die no matter what we do, but it had enough hydrogen to keep going as it is for...
