Question

Solar variability can force climate change. Which of the following statements are correct about Solar variability?
A. Flares are intense bursts of ultraviolet and X-ray emitted from the sun's outer atmosphere.
B. Sun spots are bright (hot) patches that interrupt the irregular pattern of convective cell in the photosphere.
C. Faculates are bright (hot) spots in the pattern of convective cells that often appear in conjugate with sunspots.
D. Solar activity is modulated by solar cycle of approximately 11 years.
 

• A. A, B, C, D
• B. A, B, C only
• C. A, C, D only
• D. A, B, D only

Hint:

A very common trap: Sunspots are DARK and COOL, not bright. They appear dark only because they are cooler ($\sim$3500 K) compared to the surrounding photosphere ($\sim$5778 K). The bright counterparts near sunspots are called Faculae.
