There is a sequence of events in the formation of the Northern Lights. It all starts at the sun:
- A sudden burst of energized particles from the Sun is called a solar flare.
- These charged particles leave the sun as the solar wind.
- When these particles reach Earth, they are attracted by the North and South Magnetic Poles and move towards them.
- The ionosphere is the highest level of the atmosphere, more than 50 miles (80 km) above the earth.
- In the ionosphere these charged particles collide with atoms of oxygen and nitrogen.
- The oxygen and nitrogen atoms become ionized, or excited, and they give off a burst of colored light. This burst can last from less than a second (green) to almost two minutes (red). This is similar to the way light is created in neon tubes.
- Oxygen gives off green light usually, or sometimes browny-red.
- Nitrogen gives off blue or red.
- If the collisions take place high up then oxygen gives off red. Lower down oxygen gives green and nitrogen shines blue and red. Lower down still oxygen is quiet and nitrogen still gives off blue and red.
Interestingly enough natives in the northern regions state that the lights are sometimes accompanied by a hissing noise.
The phenomenon known as the "northern lights" is caused by solar particles colliding with gases in Earth's atmosphere, creating beautiful light displays in the sky. This natural phenomenon is also called aurora borealis.
im nto sure about the south but for all i know they are called northern lights

Aurora borealis is a name for what natural phenomenon?
The aurora borealis night-sky displays are also known as the northern lights, or the northern polar lights.(or the southern (polar) lights, depending on where you live)In the Southern Hemisphere this phenomenon is also known as the aurora australis.
Are the northern lights real?
Yes, the northern lights, also known as aurora borealis, are a natural phenomenon that occur in the polar regions when charged particles from the sun interact with the Earth's magnetic field. They create colorful displays of light in the sky, usually seen at night.
Is the northeren lights a climate of Alaska?
The Northern Lights, also known as aurora borealis, are a natural light display in the Earth's sky, typically seen in high-latitude regions such as Alaska. They are not a climate, but rather a phenomenon that occurs when solar particles collide with Earth's atmosphere.
What phenomenon do solar winds cause near the earths poles?
Solar winds interacting with the Earth's magnetic field near the poles create the auroras, also known as the northern and southern lights. Charged particles from the solar wind collide with gases in the atmosphere, producing colorful displays of light in the sky.
Draw the diagram showing the Refraction Phenomenon of Light?
I'm unable to draw diagrams. However, in the refraction phenomenon of light, when light passes from one medium to another, it changes speed and bends at the interface due to the change in refractive index. This bending of light is what causes the refraction phenomenon.
What is the definition of an aurora?
A luminous atmospheric phenomenon appearing as streamers or bands of light sometimes visible in the night sky in northern or southern regions of the earth.
What is the fastest phenomenon known to man?
Light
What is the fastest known natural phenomenon?
Light, which travels at ~186,000 miles/second is the fastest known natural phenomenon.
Aurora borealis is a name for what natural phenomenon?
The aurora borealis night-sky displays are also known as the northern lights, or the northern polar lights.(or the southern (polar) lights, depending on where you live)In the Southern Hemisphere this phenomenon is also known as the aurora australis.
Where did the northern lights start?
The northern lights, also known as aurora borealis, start when charged particles from the sun interact with the Earth's atmosphere. This interaction causes the particles to emit light, creating the beautiful light display in the sky. The phenomenon can be seen in regions near the North and South Poles.
Are Northern lights and aura borialis not the same?
They are the same phenomenon. The Northern Lights are also known as the aurora borealis, a natural light display in the Earth's sky, predominantly seen in high-latitude regions near the Arctic.
Why is the Aurora borealis in the northern hemisphere?
The Aurora borealis occurs in the northern hemisphere because it is caused by solar wind particles interacting with the Earth's magnetic field near the North Pole. This interaction causes the particles to emit light, creating the stunning natural phenomenon known as the Northern Lights.
What are the northern light called as?
The phenomenon is called the aurora borealis in the Northern Hemisphere and the aurora australis in the Southern Hemisphere.
Do the northern lights emit a sound?
No, the northern lights do not emit a sound. The light phenomenon is a result of charged particles from the sun colliding with gases in Earth's atmosphere, producing beautiful colorful light displays but no sound.
How white light light makes a rainbow?
White light, if passing through a prism, can make a rainbow via the optics phenomenon known as dispersion.
What are the northen lights?
The Northern Lights, also known as Aurora Borealis, are natural light displays that occur in the polar regions. They are caused by the interaction between charged particles from the sun and the Earth's magnetic field. The result is a spectacular show of colorful lights dancing across the sky.
What are the northern light also known as?
The Aurora Borealis
