How do solar flares create Auroras?

Answer 1

The radiation emitted from solar flares skiffs across the ozone layer of the earth, at both the north and south poles, creating the phenomenon commonly know as the "Northern" and "Southern" Lights respectively.

Answer 2

The sun produces continuous solar winds that vary in intensity with the events happening on the surface of the sun. These winds are made up of thousands of tons of charged particles moving away from the sun at high velocity. Some solar flares can expel enough matter to exceed the volume of Mount Everest, traveling away from the sun in a giant bundle.

Earth's liquid nickle-iron core rotates inside the hot mantle thus producing a strong electromagnetic field around earth via the dynamo effect. The poles are located near Earth's north and south poles. When the solar wind encounters Earths magnetic field, it compresses the side its coming from. This is called bow shock. It also stretches the opposite side into a long tail. Most of the charged particles are redirected by, and flow along, our magnetic field lines. Since the field is concentrated at the poles, the charged particles are of higher intensity at the poles as opposed to the number of particles that reach the rest of the surface of Earth. If the solar wind is particularly strong, it can fold the forward field back behind the planet where it snaps into the tail. When this happens, the new forward field pushes back toward its natural place. The jostling of the magnet field creates turbulence in the solar wind. Particles can be grouped as they follow the field lines. This causes greatly increased aurora activity as many of the particles rebound along lower layers of the field.

When the particles interact with our atmosphere, they ionize some of the gas molecules in the air and make them glow. When the volume of particles traveling down the field lines at the poles increases, it increases the brightness of the aurora and produces more sheets; they can also cover more geographical area which allow them to be seen from lower latitudes.

This is how the aurora are formed and sustained.

Answer 3

Solar flares release highly charged particles and electromagnetic radiation into space. When these particles interact with Earth's magnetic field and atmosphere, they can cause the atmosphere to light up, creating auroras near the polar regions. The charged particles collide with gas molecules in the atmosphere, which then emit light in various colors.
