Q. Near-Surface Shear Layer (NSSL) was sometimes seen in the news. It is related to which of the following in solar system?
Answer: B
Notes:
Indian astronomers have found a theoretical explanation for an intriguing layer named Near-Surface Shear Layer(NSSL).
What is a Near-Surface Shear Layer(NSSL)?
- It has long been known that the sun’s equator spins faster than the poles.
- However, a peek into the internal rotation of the sun using sound waves revealed the existence of an intriguing layer where its rotation profile changes sharply.
- This layer is called the near-surface shear layer(NSSL) and exists very close to the solar surface, within which the angular velocity decreases rapidly with radius.
- Significance: Understanding NSSL is crucial for the study of several solar phenomena like sunspot formation and solar cycle.
