Answer:
1. True
Step-by-step explanation:
The sun spot is a temporary phenomenon on the sun's photosphere, that appears as the spots become darker than the surrounding areas caused by a concentration of magnetic field fluxes. They generally range from days to a month but eventually decay as they are a cycle of 11 months with some variation in length. If a similar phenomenon observed on stars is called Starspots. These spots indicate intense magnetic activity and can move across the surface of the sun in a diameter of 16 km. These patterns are called wolf numbers and have been observed in 1750.
