Solar Activity Quiz for Challenge Station

Areas on the Sun's surface that are cooler than the surrounding gas - around 4500 K.

• Coronal mass ejections

• Solar flares
• Sunspots
• Solar prominences

This is thought to arise from the circulation of electrically conductive material deep in its interior.

Why are sunspots cooler than the surrounding gas?

• Sunspots are cooler due to increased solar wind activity.
• Because of intense magnetic activity inhibiting convection.

• Sunspots are cooler due to gravitational pull from nearby planets.
• Sunspots are cooler due to lack of fusion reactions.

Plumes of hot gas that flow up from the chromosphere into the corona are called

• spicules

• solar prominences

• sunspots

• solar flares

Bright and power eruptions on the Sun that emit light, radio, and x-rays.

• Coronal mass ejections
