Aurora are caused by energetic particles that emanate from the Sun, these collide with molecules in the upper atmosphere. The collision pushes the molecules into higher energy states and when the molecules fall back to lower states they emit photons.
The Earth's magnetic field accelerates the solar particles and therefor the aurora are seen in a ring centered around the north and south magnetic poles.
What else can I help you with?
Auroras are caused by what hitting the atmosphere?
Auroras are caused by charged solar particles colliding with atoms of oxygen and nitrogen in the ionosphere, which is the highest level of the atmosphere.
Do Auroras occur in the ionosphere?
Yes, auroras occur in the ionosphere. They are caused by the interaction of charged particles from the sun with the Earth's magnetic field and atmosphere, creating a colorful display of light. The ionosphere, being part of the upper atmosphere, plays a key role in facilitating this phenomenon.
Does Mars have Auroras?
Auroras are interactions of the planet's magnetic field with the solar wind, exciting particles in the upper atmosphere. Mars' atmosphere is thin and its field weak, so such interactions as there may be would not be visible.
Auroras are caused by electrically charged particles in the?
Auroras are caused by electrically charged particles from the sun interacting with the Earth's magnetic field. When these particles collide with gases in the Earth's atmosphere, they produce beautiful light displays known as auroras.
Visible light given off by excited atoms and molecules in the upper atmosphere?
The visible light given off by excited atoms and molecules in the upper atmosphere is commonly known as auroras. These light displays are caused by solar wind particles interacting with the Earth's magnetic field and atmosphere, resulting in the emission of colorful light. Auroras are often seen near the poles and are known as the Northern and Southern Lights.
What produces the Auroras?
Auroras are produced when charged particles from the sun (solar wind) interact with the Earth's magnetic field and atmosphere. This interaction causes the particles to emit light, creating the colorful displays known as auroras.
What are the Auroras caused by?
Auroras are caused by charged particles from the sun interacting with Earth's magnetic field. These particles are directed towards the Earth's poles, where they collide with gases in the atmosphere, creating the colorful light displays known as auroras.
How big are Auroras?
Auroras have no definite size. They occur when charged particles from the Sun ionize particles in the upper atmosphere as they spiral in toward Earth's magnetic field. Auroras may be localized in one area, or may extend from horizon to horizon in the sky.
Why don't we see auroras on the moon?
The auroras we see on Earth are a result of Earth's magnetic field funneling high-energy particles from the sun into Earth's upper atmosphere, where excited electrons in gas molecules create a glow. The moon has no magnetic field and no atmosphere.
What causes auroras on the moon?
Auroras on the moon are caused by the interaction of the solar wind and the moon's surface. Charged particles from the solar wind interact with the moon's magnetic field, resulting in auroras. However, the moon's lack of a significant atmosphere means the auroras are much fainter than those seen on Earth.
Does Mercury have Auroras?
No, it has no atmosphere.
How are Auroras created?
Coloured glows called auroras are common around the Earth's polar regions. They are caused by streams of particles from the sun that are attached to the magnetic poles as the particles hit the earth's upper atmosphere they cause atoms of gas to glow. Auroras can look like huge curtains hanging in the sky, slowly changing shape. Sometimes they are seen over a much wider area, particularly when the sunspot activity is high.
