During which event does the Moon come between the Earth and the Sun, casting a shadow on Earth?
Show answer & explanation
Correct answer: B
Explanation
Solution: The correct answer is Solar Eclipse.
Explanation:
☛ A Solar Eclipse occurs when the Moon passes directly between the Sun and the Earth, blocking sunlight and casting a shadow onto Earth.
☛ This celestial alignment can occur only during the New Moon phase.
☛ There are three primary types of solar eclipses: Total, Partial, and Annular.
☛ The darkest inner part of the shadow where sunlight is completely blocked is called the Umbra, while the lighter outer region is called the Penumbra.
Extra Exam-Relevant Facts:
☛ Lunar Eclipse: Occurs when the Earth comes directly between the Sun and the Moon, casting Earth's shadow onto the Moon; it occurs only on a Full Moon night.
☛ Equinox: Occurs twice a year when the Sun is directly above the equator, resulting in nearly equal lengths of day and night worldwide (around 21 March and 23 September).
☛ Syzygy: The astronomical term for a straight-line configuration of three celestial bodies (such as the Sun, Earth, and Moon).
☛ Diamond Ring Effect: A well-known phenomenon observed just before and after totality in a total solar eclipse.
