Explanation :

Total Solar Eclipse

• It occurs when the Moon completely blocks the solar disk.
• In a total solar eclipse, the narrowest part of the path (where the Sun is completely blocked and the Moon casts its darkest shadow (called the umbra)) is called the “zone of totality”.
• A phenomenon called “Bailey’s Beads” often appears as sunlight shines out through valleys on the lunar surface.

Annular Solar Eclipse

• An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring).

Partial Solar Eclipse

• It occurs when Earth moves through the lunar penumbra (the lighter part of the Moon’s shadow) as the Moon moves between Earth and the Sun.
• The Moon does not block the entire solar disk, as seen from Earth.
• Depending on location during a partial eclipse, one might see anything from a small sliver of the Sun being blotted out to a nearly total eclipse.
