What are the 2 sources of energy for all life on earth?
Sun and Food ( that includes water)
How can solar energy replace conventional sources of energy in various fields?
Solar energy is a renewable energy source. It is sourced from the sun, which in human timeframes has a long life for energy output. Solar energy is therefore an almost infinite energy source. Most convential energy sources (uranium, coal, oil, gas, etc.) are unrenewable. Such energy sources are sourced from the earth and so are finite. The timeframes for the "finite-ness" of conventional energy sources vary and are disputed. Conventional energy sources also produce negative by-products through their conversion to thermal energy, kinetic energy, and electric energy, such as radioactive waste, sulphur, CO2, etc. Solar energy is a clean (i.e. minimal negative by-products) but diffuse energy source. Current technology developed to capture solar energy is inefficient in capturing and concentrating the energy for distribution and use as thermal energy, and electrical energy, compared to conventional sources.
What the world would be without light?
Without light the world would be a lifeless rock. if light was to disappear today there would still be sources of energy available that were previously converted by plants from the sun. But from the point of view of life as we know it there would be nothing within a very short time. It would become so cold that the atmosphere would freeze.
What is the excessive use of conventional energy?
energy can be in forms of heat light and sun as well as energy resources like electricity,gas,power,water and etc. if these energy resources are used excessively it will have greater effect on man,s life and routine.
How does the sun help the earth besides providing light?
The sun gives the Earth warmth and energy, without which it would be impossible for life to exist. Also, without the sun, it is unlikely that Earth would have ever formed, because it formed out of a disc of debris that circled the sun.
Why is light energy important in your life?
light energy is important in your life because without light energy how will you see whats going on around you
Why light is important in your life?
light energy is important in your life because without light energy how will you see whats going on around you
How is photosythesis important to life on earth?
They Say It's Important Cause it Gives Energy and light .
Why is light energy important within your body?
The light energy within your body is not only important it is essential. The body energy is flowing in and thru the Central Nervous System actually providing the body, Life. That energy is Life itself. You are an individual unit of all life. The life energy in your body is custom designed just for you compliments of the registere owner. GOD.
Sources of energy for life?
it is the sun
How can life can flourish at great depths where light cannot penetrate?
1) non-light energy sources (see hot vents). 2) live on ditrious that falls down from the surface.
Why are energy and electricity important to us?
Energy is important because there is no life without energy. All living things need energy. Electricity is important because it is the kind of energy that holds the universe together. Every atom involves electricity. Electricity is important because it is transmittable through space at the speed of light.
What kind of energy drives all the processes important to life on earth?
The energy from the Sun, solar energy drives all the process important to life on Earth.
What are the two sources of energy the fuel life on earth And explain how they do so?
No
Is the sun the source of energy in most energy resources?
The Earth has two sources of energy, the sun's radiation and heat from inside the Earth. The sun is most important and life could hardly exist except at a very primitive level without it.
What kind of energy drive all processes important important to life on earth?
Solar energy drives all the processes important to life on Earth.
What is thermosynthesis?
Thermosynthesis refers to an at this moment still theoretical idea that organisms could be able to make use of heat as an energy source: the word ' thermosynthesis' is derived from the word 'photosynthesis'. The experimentally observed biological energy sources are light and food, and heat would represent a very different category. Thermosynthesis would not make generate much energy. It is however of interest for models for simple energy sources during the origin of life and for energy sources for extraterrestrial life. Go to www.scirus.com and search for thermosynthesis to find pertinent scientific publications on the subject.
