Which term is a stream of charged particles produced by the sun's corona?

• A. Solar wind
• B. Penumbra
• C. Cohesion
• D. Doldrums

Answer: (A)

Charged particles streaming away from the sun’s outer atmosphere are called the solar wind. The corona’s extreme heat gives the particles enough energy to break free from the sun’s gravity, creating a continuous outflow of plasma—mostly protons and electrons—that fills the solar system. This wind interacts with planetary magnetic fields and can produce phenomena like auroras on Earth. The other terms refer to different concepts: penumbra is a partial shadow around a sunspot or eclipse; cohesion is the attraction between like molecules; doldrums are a calm wind region near the equator. The term that matches a stream of charged particles from the sun’s corona is the solar wind.
