Carrie is making a presentation on solar winds. Her notes of the steps that must occur for solar winds to form are below.1. The stream of electrically charged particles collide with gas atoms, causing the latter to give off light.2. The electrically charged particles flow outward in all directions as far as Saturn.3. The stream of electrically charged particles flows outward from the corona.4. The particles of the solar wind flow along lines of the magnetic field.Which shows the correct sequence in the formation of solar winds?
