Trent Alexander · Answer 1

The solar wind is a stream of charged particles made mostly of electrons and protons that flows outward from the Sun. It is caused by the hot solar corona expanding into the space. Corona is denser than the solar wind due to its ionized charged particles. Because solar winds are less dense than corona, they can travel 900km/s sometimes reaching the ionosphere of the earth.

Reginald Fry · Answer 2

The Corona although being the least dense layer of the Suns atmosphere is denser than the Solar winds that it generate which can leave the Suns own atmosphere and reach the Earth's ionosphere from time to time, this difference is due to ionized charged particles in the Corona which are not present in the Solar wind.
