Which phenomenon is caused by the collision of solar winds with Earth's magnetic field?

The phenomenon that results from the collision of solar winds with Earth's magnetic field is the aurora borealis. When charged particles from the solar wind interact with the Earth's magnetosphere, they can cause tremendous energy release. This energy is then converted into light, producing the beautiful displays associated with the auroras.

Auroras occur mainly in polar regions because the Earth's magnetic field directs the solar wind towards the polar areas, allowing these interactions to happen most effectively there. This luminous display is fundamentally different from a bow shock wave, which refers to a type of shock wave formed when a solar wind encounters a barrier created by the magnetic field, leading to a distinct separation of these two phenomena. Thus, the aurora borealis is clearly a direct result of solar wind interactions, making it the correct choice.
