Answer 2

Peculiarity of the earth and moon related to light causes eclipse.

• The Moon occasionally passes between the Sun and Earth as it revolves around the Earth. When this occurs, the Moon prevents the Sun's light from reaching Earth. This results in a solar eclipse—an eclipse of the Sun. Earth is shaded by the Moon during a solar eclipse.
• The moon experiences a lunar eclipse when Earth blocks the moon's access to sunlight, casting a shadow on its surface. During a lunar eclipse, the sun-blocking Earth creates two shadows that fall on the moon: the umbra, which is a full, dark shadow, and the penumbra, which is a partial outer shade.
• When the Moon passes directly between the Sun and Earth, it creates a solar eclipse by casting its shadow across the planet. Only a new moon may cause a solar eclipse. The angle between the Moon's orbit and the Earth's orbit around the Sun is 5 degrees.
• The new moon, the moon crossing the plane of Earth's orbit, and the moon's distance from Earth are the three cycles that interact to produce eclipses. Each cycle repeats on a slightly different time scale.
• A solar or lunar eclipse occurs when the Sun, Moon, and Earth are in alignment. When the Moon blocks the Sun's light, as it will do on August 21, a solar eclipse occurs. A lunar eclipse occurs when the Moon enters the shadow of the Earth as it moves behind it.
