Below are sample questions representative of the exercises included on this worksheet and related 9.145 The Sun Structure, Fusion, and Space Weather skill assessments:

Problem 1Difficulty: Mastery

Which statement is the best overall systems summary of the Sun and space weather?

AChemical burning powers the Sun, sound carries energy through space, and rain clouds create solar flares.

BFusion powers the Sun, radiation transfers energy to Earth, and magnetic activity can send particles and fields that affect technology.

CThe Moon powers fusion, the corona blocks all light, and satellites are unaffected by solar activity.

DEarth's oceans power the Sun, sunspots are shadows, and space weather is ordinary wind.

Solution & Explanation:A complete summary connects fusion, electromagnetic radiation, magnetic activity, charged particles, and real effects on near-Earth technology.

Problem 2Difficulty: Mastery

Use the solar-event comparison table. Which row best describes a coronal mass ejection?

AA steady stream of charged particles flows outward from the corona.

BA sudden burst of electromagnetic radiation occurs and reaches Earth in minutes.

CA cooler dark region appears on the photosphere because convection is reduced.

DA large cloud of plasma and magnetic field leaves the corona and may disturb Earth's magnetosphere.

Solution & Explanation:A CME is a large eruption of plasma and magnetic field. It differs from a flare, sunspot, or the steady solar wind.

Problem 3Difficulty: Mastery

Which explanation best connects sunspots and solar flares without claiming they are the same thing?

ASunspots are solar flares that have cooled into rocks.

BSunspots mark magnetic active regions where stored magnetic energy can be released in flares.

CSunspots and flares are unrelated to magnetic fields.

DSolar flares are shadows cast by sunspots on Earth.

Solution & Explanation:Sunspots and flares are different phenomena, but both are linked to magnetic activity on the Sun.
