Does lighting come from the ground or from the sky?

natural LIGHTING comes from the sun,\notherwise, usually from an electric light bulb\n\nHowever, LIGHTNING, is a dual attraction between the sky and the ground, but physically speaking the negative charge in the sky is seeking out a positive charge on the ground, the LIGHTNING comes FROM THE SKY.\nHowever, you may not often see this and since there is a return of the lightning energy back up to the sky, (to balance the energy) so if you look after the sound of thunder you are seeing the return.

The 'sky' that you see is not of a solid substance, it is merely molecules in the air scattering light. In this case, most of the time a blue light. At night, the sun disappears and you will see space (the sky has 'disappeared' and now you see beyond the sky), while in actual fact the molecules that create the sky are still there, they are not refracting light. \n\nGravity on earth cannot pull any more particles closer to earth and as such the sky remains staticly placed in the sky forever standing.

Blue sky is cause the the defraction of blue light in the atmosphere... at night there is no light to defract....

All objects in our solar syatem get their light from our sun. How? Light travels from the sun and is reflected by the object, in this case the moon, and we see the reflected light.

There is light in space. After all, the light we see on Earth from the Sun, the moon, and the stars travels through space to get here. \n\nThe big difference between Earth and space is that our atmosphere reflects the light that goes through it. So it makes our surroundings seem brighter. Since space doesn't hold an atmosphere there is nothing to reflect the light and it just passes through.\n\nSo basically light is always travelling through space but it doesn't get reflected (which makes it dark).\n\nHope that makes some sense.

Actually, electrical charges from the ground meet charges from the sky.  We  live in a magnetic field of 219v-dc.   Charges build up in clouds and are attracted to charge harbored within the earth.

For example,discontinuities in the canopy mean that sunbeams occasionally pass rightdown to ground level, producing sunflecks. Quite suddenly and lasting foronly a few minutes, deeply shaded leaves may receive a tenfold increase inlight flux from sunflecks.

The moon gets its light from the sun!  Way out in outer space, the sun produces light and heat.  The sun's energy is reflected off the surface of the moon and bounced back to the Earth.  What we see is the reflection of the sun's light on the moon.

Regular light. It is not a lazer or any special kind of light, just "light". It is probably generated by a specialized piece of equipment, but it is just light - photons. It probably doesn't contain ultra violet light like sunlight, it is probably closer to artificially created light like that from a lightbulb.

I don't know but I have seen some weird stuff in the sky. I saw this light go back and forth very fast a couple of times then disappear straight up into the sky. I also used to see these weird upside down arch shape clouds in the sky just barely moving. Bonafide Alien Space Craft or Aerial Government Experiment, I don't know.

On one can tell lighting is different every time.\nJust like it does not hit the same place two times in a row.

Lighting is static electricity of charged particles in our atmosphere. The difference in the charges causes lightning. It is not often (If ever) for ground to cloud strikes over water. Water is a grounding source, since water is highly conductive (Salt water like oceans more so than fresh water like lakes and ponds.)and it is electrically, and physically grounded, the electrical energy is both grounded, and dissipated by the large volume of conduction.

The angle the sunlight comes on determines how intense light on that area of ground will be.  If a position on the earth has the sun at its zenith (directly above) then the light on that small area will be coming close to directly to that point.  A plane tangent to that point on the earth would be (sort of) perpendicular to the arriving photons and receive the maximum intensity of light per area.\n\nIf you are talking about the sun coming from an angle then the sun will have to travel through more atmosphere which will absorb more of the light and result in less intensity.  Also, since the light is coming on an angle it will be spread out onto a larger area than if it were coming from directly above.\n\nThe earth's distance from the sun varies slightly throughout the year which means that when we are close the sunlight is a bit more intense and when we are further it is a bit less intense.\n\nThe sun makes temperatures different in seasons because of how much time it spends in the sky where you are per day and how close to being directly overhead it is while it is in the sky.  The more time closer to being directly overhead the more intense the light is and the more time there is for it to be absorbed and heat things up.\n\nIntervening water and particulate matter in the air blocks sunlight and reduces intensity as well.  That means dust, pollution, humidity, clouds will affect intensity of sunlight to a place on the earth.

Lightning is electricity. When the clouds build up too much electrons and the voltage between the cloud and the ground is great enough to cause air to break down and conduct, you get lighting. Its like a spark.

b'coz in street light are placed at almost constant distance from each othere. the shadow wil appear opposite side of street light means if street poll is in fornt of u and u r near to the poll then shadow will be behind u and simillarly poll is behind u and and if u r near to that poll then shadow will be in front of u.\nthis is due to intensity.

Yes. Anywhere that there is lightning there is a possibillity for red lighting. Red lightning is caused by, lighting traveling from cloud to cloud. The clouds then distort the color.
