Ответ:
C. Influenced by the Sun's electromagnetic field
Explanation:
"Sunspots occur in pairs because each is one side of a loop of the Sun's magnetic field that reaches the Sun's surface. Solar prominences are the plasma loops that connect two sunspots."
Ответ:
Option 'D' is correct.
Explanation:
Earth has one natural satellite i.e. "Moon".
Earth spins on its axis due to moon is tidally locked.
The mass of moon is much greater than the mass of earth.
The age of moon is much older than the age of Earth.
The moon is older than Earth by approximately 300 million years.
so, only one statement is correct i.e. 'D'.
Hence, Option 'D' is correct.
