The Sun, a colossal sphere of incandescent plasma, blazes at the center of our solar system, radiating immense energy that sustains life on Earth. Its surface, a turbulent sea of fiery gases, features swirling sunspots and explosive solar flares, all enveloped in a halo of ethereal corona during eclipses. As it rises each morning, it bathes the world in golden light, warming the air and casting long shadows, while its gravitational pull orchestrates the dance of planets in their orbits. This eternal star, composed mostly of hydrogen and helium, fuses atoms in its core to unleash heat and light, a ceaseless furnace that has illuminated the cosmos for over 4.6 billion years.

A. Core
B. Photosphere
C. Corona
D. Chromosphere
Answer: C. Corona
Explanation: The corona is the Sun’s outer atmosphere, which becomes visible as a halo during a total solar eclipse.
5. What is a solar flare?
A. A spot on the Sun’s surface
B. A sudden burst of energy and radiation
C. A ring around the Sun
D. A type of solar wind
Answer: B. A sudden burst of energy and radiation
Explanation: Solar flares are explosive events on the Sun’s surface that release massive amounts of energy, affecting space weather.
6. How long does it take for sunlight to reach Earth?
A. 8 minutes
B. 1 hour
C. 24 hours
D. 1 day
Answer: A. 8 minutes
Explanation: Light from the Sun travels at about 300,000 kilometers per second, taking approximately 8 minutes to reach Earth.
7. What causes sunspots on the Sun?
A. Hotter regions on the surface
B. Magnetic activity
C. Atmospheric pressure
D. Solar winds
Answer: B. Magnetic activity
Explanation: Sunspots are cooler, darker areas caused by concentrations of the Sun’s magnetic field lines.
8. Which planet is closest to the Sun?
A. Earth
B. Mars
C. Mercury
D. Venus
Answer: C. Mercury
Explanation: Mercury is the innermost planet in our solar system, orbiting closest to the Sun.
9. What is the Sun’s diameter compared to Earth’s?
A. About 10 times larger
B. About 100 times larger
C. About 1,000 times larger
D. About 109 times larger
Answer: D. About 109 times larger
Explanation: The Sun’s diameter is approximately 1,392,000 kilometers, while Earth’s is about 12,742 kilometers.
10. What is the solar wind?
A. A stream of particles from the Sun
B. A type of solar eclipse
C. The Sun’s rotation speed
D. Heat waves from the Sun
Answer: A. A stream of particles from the Sun
Explanation: Solar wind is a flow of charged particles, primarily electrons and protons, emitted from the Sun’s upper atmosphere.
11. How often does the Sun complete a full rotation on its axis?
A. Every 24 hours
B. Every 25 days at the equator
C. Every 365 days
D. Every year
Answer: B. Every 25 days at the equator
Explanation: The Sun rotates once every 25 days at its equator, though slower at the poles due to differential rotation.
12. What is the chromosphere?
A. The Sun’s core
B. A layer above the photosphere
C. The outermost layer
D. A region of sunspots
Answer: B. A layer above the photosphere
Explanation: The chromosphere is a thin layer of the Sun’s atmosphere between the photosphere and the corona.
