Astronomers recently discovered small plasma loops in the Sun's lower atmosphere. These micro loops are exceedingly small and short-lived, which has made them impossible to identify until now.

Practice Question: Q. With reference to Miniature Plasma Loops recently observed on the Sun, consider the following statements: 1. Miniature plasma loops are tiny arch-like structures observed in the Sun’s corona. 2. These loops are believed to contribute to the process of coronal heating. 3. They are formed by the interaction between solar wind and Earth’s magnetic field. Which of the statements given above is/are correct? A) 1 and 2 only B) 2 and 3 only C) 1 and 3 only D) 1, 2 and 3 Answer: A) 1 and 2 only Explanation: Statement 1: Correct – Miniature plasma loops are small, arch-like structures in the Sun’s outer atmosphere (corona). Statement 2: Correct – These loops may play a role in explaining the mystery of coronal heating, where the Sun’s corona is hotter than its surface. Statement 3: Incorrect – The loops are not related to the Earth’s magnetic field or the solar wind interaction with it. They are internal to solar atmospheric dynamics. |
