🌌 Cosmic Exploration · Quiz 012

Move from the Sun's stable structure to its magnetic activity and the different ways solar disturbances can affect near-Earth space.

Learning goalDistinguish major forms of solar activity and connect different solar disturbances to their timing and effects near Earth.

FoundationWhat are sunspots?
Need a small nudge?

Think about solar magnetism and why some patches of the visible surface appear darker.

UnderstandingWhich statement correctly distinguishes a solar flare from a coronal mass ejection, or CME?
Need a small nudge?

Separate a burst of radiation from an eruption that carries matter and magnetic field outward.

ApplicationA strong solar flare occurs on the Earth-facing side of the Sun. Which effect can begin on the sunlit side of Earth only minutes later because the disturbance travels at the speed of light?
Need a small nudge?

Look for an effect driven by electromagnetic radiation rather than by a slower-moving cloud of plasma.

InterpretationWhich observation most directly indicates that a coronal mass ejection has occurred rather than only a solar flare?
Need a small nudge?

A CME is defined by material and magnetic field leaving the corona.

ConnectionObservers record a strong solar eruption. Minutes later, HF radio communication is disrupted on Earth's sunlit side. About two days later, auroras intensify and GPS accuracy degrades during a geomagnetic storm. Which explanation best fits the sequence?
Need a small nudge?

Use the different travel times of electromagnetic radiation and bulk plasma.
