Charged particles come from the sun, especially after sunspot activity and solar flares. They stream through space and are attracted to the magnetic poles of the earth. In the ionosphere they collide with oxygen and nitrogen atoms, which give out green, blue and red light.
This light is known as the Aurora Borealis, or Aurora Australis, the Northern and Southern Lights.

How particles would move in gel electrophoresis according to size?
During gel electrophoresis, the smaller particles move faster than the larger ones. The end of the gel where the samples are loaded is called the sample origin. Samples move from the origin toward the opposite electrode according to size. At the end of the run, smaller particles will have migrated farther from the origin and the larger ones will be found closer to the origin
How fast meteors are?
Meteors, or "shooting stars," typically travel at speeds ranging from 25,000 to 160,000 miles per hour (40,000 to 257,000 kilometers per hour) as they enter Earth's atmosphere. The speed can vary based on the meteor's origin and the angle of entry. When they collide with the atmosphere, they create a bright streak of light due to the intense friction and heat generated by their rapid descent. Most meteors burn up before reaching the ground, but those that survive are called meteorites.
What are the origins of the earth's motion based on the origin of the galaxy and its solar system?
The origin is in the random motions of all the particles that came together under the mutual force of gravity. Suppose two objects approach each other, but don't actually collide. If they come close enough the force of attraction between them causes them to go into an orbit round each other (round their common centre of gravity). In a cloud of particle the same basic process produces a spinning disc which with further compression can eventually produce a star.
What is the theory for the origin of planetary ring particles?
The theory for the origin of planetary ring particles suggests that they are remnants of moons or asteroids that were shattered by collisions. Alternatively, they may also be the result of material that never fully coalesced into a moon due to gravitational forces from the planet.
Is the Aurora Borealis found in the mesosphere?
The Northern lights can be seen round the magnetic North pole of the Earth in the Arctic Circle. High energy particles of the Solar wind are guided to Earth down field lines and excite air molecules to glow. The Aurora Australis occurs over Antarctica
What was the biggest change in the earths atmosphere between the precambrian and the paleozoic eras?
The origin of free oxygen
What is the origin of the northern lights?
The northern lights, or aurora borealis, originate from the interaction between charged particles emitted by the sun, known as solar wind, and the Earth's magnetic field. When these particles collide with gases in the Earth's atmosphere, particularly oxygen and nitrogen, they produce brilliant displays of light. This phenomenon primarily occurs near the polar regions, where the magnetic field lines converge, allowing more particles to enter the atmosphere. The result is a stunning array of colors, predominantly green, pink, and red, visible in the night sky.
What is a cosmic ray?
Cosmic ray: A ray of radiation of extraterrestrial origin, consisting of one or more charged particles such as protons, alpha particles, and larger atomic nuclei. Cosmic rays entering the atmosphere collide with atoms, producing secondary radiation, such as pions, muons, electrons, and gamma rays. Cosmic rays (and secondary radiation) can be easily seen in a cloud chamber.(American Heritage Dictionary, 2005)
What theory best describes the moon origin?
Presently, the ejected ring theory best describes the origin of moon.

Who is the scholars suggested the earths origin from gas and dust particles?
The theory suggesting that the Earth originated from gas and dust particles is known as the Nebular Hypothesis. It was proposed by scientists such as Immanuel Kant and further developed by Pierre-Simon Laplace in the 18th century. This hypothesis states that the solar system formed from a rotating disk of gas and dust around the young sun.
What is the origin of plants abilities to fight diseases?
the American medical association called for the protection of earths diversity
What caused an aerobic atmosphere during the history of the earth?
The origin of photosynthetic prokaryotes caused an aerobic atmosphere during the history of the earth.
When air molecules collide with things around us it produces what?
When air molecules collide with objects, they can produce sound waves. These sound waves travel through the air and reach our ears, allowing us to hear the sound created by the collisions.
What is the origin of the element of mendelevium?
Mendelevium was obtained in 1955 after the bombardment of 253Es with alpha particles in a cyclotron.
