Correct Answer

C

Explanation

A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking the Sun's light and casting a shadow on the Earth. There are two main types of solar eclipses:

1. Total Solar Eclipse: During a total solar eclipse, the Moon completely covers the Sun, and for a brief moment, the Sun's corona (the outer atmosphere) becomes visible as a halo of light around the Moon. This is a rare and spectacular event that can only be observed within a relatively narrow path on Earth.

2. Partial Solar Eclipse: In a partial solar eclipse, the Moon partially covers the Sun, creating a crescent shape. This is visible from a broader area on Earth but is not as dramatic as a total eclipse.

The occurrence of a solar eclipse is not regular, as the Moon's orbit is tilted with respect to the Earth's orbit around the Sun. Therefore, solar eclipses happen only when the Earth, Moon, and Sun are in alignment, which typically occurs a few times a year at different locations on Earth. When a solar eclipse happens, it is important to use proper eye protection, such as solar viewing glasses, to safely observe it, as looking directly at the Sun can be harmful to your eyes.
