Write what each word means, using the article.

Do not copy the article. Write two things you learned, the way you would explain them to a friend.

Answers below are taken from the article’s stored facts, so they match what the student read.

1. What is the scientific classification?Plasma outflow from stellar atmospheres
2. What is the primary drivers?Thermal pressure, radiation pressure on spectral lines, and magnetic field interactions
3. Why does the Sun send out a solar wind?The Sun's hot corona gives particles enough energy to escape, and its magnetic fields help push them out. This wind travels through the solar system.
4. How fast can stellar winds move?In big stars like O and B types, winds can reach speeds over 2,000 km/s. Smaller stars have slower winds.

Interstellar Medium (ISM): The matter and radiation that exist between the star systems in a galaxy.
Plasma: A state of matter consisting of ionized gas, where electrons are stripped from atoms, creating a soup of ions and free electrons.
Stellar Wind Bubble: A cavity in the interstellar medium created by the high-velocity outflow of stellar wind from a star.
