What are Auroras produced by?
The sun is constantly releasing charged particles out into space (electrons, protons, etc). This is known as the Solar Wind. Occasionally, a solar flare or coronal mass ejection releases a significant quantity of these particles (millions or even billions of tons of them). When they impact the Earth's magnetic field, they can cause the magnetic field lines to break and reconnect, which causes the charged particles to rush towards the poles. When these particles hit the upper atmosphere, they react with the atoms and molecules of the air and cause them to glow with the characteristic colours associated with the aurora.
How could Rutherford tell where the positivily charged particles went after hitting the gold foil?
Rutherford could determine the paths of positively charged particles (alpha particles) after they hit the gold foil by observing their scattering patterns. Most alpha particles passed through the foil, but some were deflected at large angles or even bounced back, which indicated that they encountered a dense, positively charged nucleus at the center of the gold atoms. By analyzing the angles and frequencies of these deflections, he inferred the existence and location of the nucleus, leading to the conclusion that atoms have a small, dense core surrounded by mostly empty space.
What was the source of molten rock on the newly formed moon?
Probably Earth. It is assumed that in the very early life of the Earth it was hit by an object the size of Mars, resulting in matter ejected from the Earth, forming the Moon.
Explain why auroras are seen mostly near the north pole and south pole?
An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes accompanied by a crackling sound. The Aurora Australis appears around Antarctica and the Aurora Borealis appears around the Arctic.
In what part of the atmosphere does solar particles hit atoms and cause them to glow?
In the very highest layer of the atmosphere, the ionosphere, solar particles collide with oxygen and nitrogen atoms and green, blue and red light is given off.This light is the http://wiki.answers.com/FAQ/7810
Where do the colours come from in the northern and southern lights?
The colors in the northern and southern lights are created by charged particles from the sun interacting with gases in the Earth's atmosphere. These gases emit different colors when they are hit by the charged particles at high speeds. Oxygen produces green and red colors, while nitrogen produces blue and purple colors.
How is the Aurora Australis formed?
The Aurora Australis in the southern hemisphere, (and Aurora Borealis in the northern hemisphere) are magnificent displays of coloured light. They result from collisions between electrically charged gaseous particles in the Earth's atmosphere with charged particles from the sun that enter the atmosphere. Sunspot activity causes electrons and protons from the sun to be blown towards the earth on the solar wind. The different colours are caused by the different types of gas particles. The reason they occur more at the poles is that earth's magnetic field, which usually deflects the particles, is weaker there, allowing the particles to enter. Some particles are attracted by the magnetic poles due to the electromagnetic behaviour of charged particles, which causes the particles to be led down the lines of magnetic flux until they hit the atmosphere.

How does the Earth's magnetic field help people?
The Earth's Magnetic shield is important for preventing the Atmosphere from being destroyed by solar wind by deflecting dangerous particles from impacting the Earth.It protects Us from the magnetic / electrical radiation that comes from the Sun. High radiation periods coincide with solar storms.It protects us from solar radiation (wind) from the sun
How is the aurora borealis connected to the solar flares?
When a solar flare is ejected from the sun it releases billions of positively charged particles (ionized) particles. When these particles hit the earths magnetic feild it produces the aurora borealis.
When charged particles from the sun hit oxygen and nitrogen atoms in air what is formed?
When charged particles from the sun hit oxygen and nitrogen atoms in the air, they can ionize these atoms and form ions such as O+ and N+. These ions can interact with other molecules in the atmosphere, leading to the creation of various compounds and reactions such as ozone formation.
What is a kid friendly definition of ionosphere?
The ionosphere is the part of the earth's atmosphere (the layers of gases that surround the earth and stay there because of the earth's gravity) where sunrays are able to ionize some of the gas substance. This means that the gas substances, because of the high amounts of energy in the sunrays hitting them, lose or gain electrically charged particles (such as electrons, the tiny charged particles orbiting the atom core, or ions, larger, electrically charged particles) and themselves become electrically charged. Electrical charge is responsible for the fundamental force of physics called electromagnetism, which is what creates magnetism and electricity. Because of this electromagnetism in the ionosphere, when large bursts of sunrays hit the atmosphere from time to time the amazing northern lights and southern lights, the auroras, become visible in the far north and far south of our planet.
What was the purpose of the fluorescent screen in rutherfords experiment?
The purpose of the fluorescent screen in Rutherford's experiment was to detect the alpha particles that were deflected when they struck the gold foil. The screen would light up when hit by the alpha particles, allowing Rutherford to observe and measure the deflection pattern and infer the structure of the atom.
What may result when charged particles from solar wind hit the earths atmosphere?
When charged particles from the solar wind collide with the Earth's atmosphere, they can create stunning natural phenomena such as auroras, commonly known as the Northern and Southern Lights. These interactions can also lead to disturbances in the Earth's magnetic field, potentially affecting satellite operations and communication systems. Additionally, increased particle activity can enhance radiation exposure at high altitudes, posing risks to astronauts and high-flying aircraft.
What layer is hit by the sun's ultraviolet rays and cause the air particles to become electrically charged?
The ionosphere. To clarify, only the low-frequency radio waves incorrectly called "high-frequency" or "HF" of about 50MHz and below are reflected. "Very High Frequency" VHF signals are not reflected, but go straight off into space. For example, in the "AM" commercial broadcast spectrum, the transmission is reflected back to the Earth and is receivable for great distances, a phenomenon that used to be called "skip". AM signals are in the band of 550KHZ to 1.6 MHz. "FM" stations in the band from 88MHz to 108MHz are only received by "Line of sight" transmissions.
What region of the atmosphere where auroras occur?
Auroras occur in the thermosphere, which is the region of the atmosphere located between the mesosphere and the exosphere. This is where charged particles from the sun interact with gases in the Earth's atmosphere, creating the colorful light displays known as auroras.
How are the Northern Lights - Aurora Borealis - related to the earth's magnetic field?
An Aurora Australis or an Aurora Borealis occurs when streams of particles from the sun's solar winds hit the earth's atmosphere at an angle (as can only happen at the poles). These particles interact with the edges of the earth's magnetic field and when they collide with the gases in the ionosphere, the particles glow creating curtains of blue, green and magenta. An aurora is sometimes said to be accompanied by a crackling sound, but this has never been recorded and scientists are at a loss to explain what causes the sound.
