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

• A. Solar wind
• B. Umbra
• C. Penumbra
• D. Transpiration

Answer: (A)

The sun's corona emits a steady stream of electrically charged particles into space, called the solar wind. The corona’s extreme temperature gives particles enough energy to escape the Sun’s gravity, creating a flowing plasma that fills the solar system and interacts with planetary magnetic fields. This solar wind drives space weather and can affect satellites and power systems on Earth. The other terms describe shadows and a plant process, not energetic solar emissions: the dark central part of a shadow and the lighter surrounding region are shadows-related concepts, while transpiration is water loss from plants.
