A student researching solar flares has taken notes:
• Solar flares are massive explosions on the sun's surface • They release energy equivalent to millions of nuclear bombs • Flares can disrupt satellite communications and power grids • The sun follows an approximately 11-year activity cycle • Space weather forecasting helps prepare for solar events
The student wants to explain why solar flares matter to modern society.
Solar flares are massive explosions releasing energy equivalent to millions of nuclear bombs.
Solar flares matter because they can disrupt satellite communications and power grids that modern society depends upon.
The sun follows an approximately 11-year cycle of solar activity.
Space weather forecasting helps authorities prepare for major solar events.
