From the internet, given options:
The solar wind produces the northern and southern lights.
The solar wind can cause the formation of new elements.
The solar wind causes temperature changes on Earth's surface.
The solar wind disrupts communication systems.
The solar wind distorts Earth's magnetic field.
Answer:
The solar wind produces the northern and southern lights.
The solar wind disrupts communication systems.
The solar wind distorts Earth's magnetic field.
Solar winds are very energetic particles moving at a velocity of about 905km/s from the sun. They are made up of extremely hot particles from the outer atmosphere the sun called the corona. These particles consists of electrons, protons, plasma flowing outward into the solar space from the sun.
Due to their nature, they are know to produce the northern and southern light known as aurora when they come in contact with the earth atmosphere.
Solar winds disrupts radiowaves which are known as the facilitators of communication systems.
They also disrupt the magnetic field of the earth. These jets streams can interact with the earth magnetic field.
