What is a symbol of a solar wind's impact on Earth?

The symbol of a solar wind's impact on Earth is best represented by magnetic storms. Solar winds are streams of charged particles emitted by the sun, and when these particles interact with Earth's magnetic field, they can cause significant disturbances. These disturbances are known as magnetic storms or geomagnetic storms.

During such events, energetic particles collide with atoms in the atmosphere, leading to various phenomena, including auroras. The disturbances can also affect satellite operations and communication systems, illustrating the intricate relationship between solar activity and Earth's magnetic environment. Other options, while they may relate to aspects of climate or ecosystem changes, do not directly characterize the phenomenon caused by solar wind in the context of Earth's magnetic storms.
