What describes a solar eclipse?

• A. Earth passes between Sun and Moon, blocking sunlight.
• B. Moon orbits Earth.
• C. Sun passes between Moon and Earth.
• D. Moon passes between Sun and Earth, blocking sunlight.

Answer: (D)

A solar eclipse happens when the Moon moves directly between the Sun and the Earth, so the Moon blocks some or all of the Sun’s light from reaching parts of the Earth. Seeing a total, partial, or annular solar eclipse depends on how perfectly the Moon covers the Sun from our point of view. The statement that describes this event is the Moon passes between the Sun and the Earth, blocking sunlight. The other scenarios describe different things: Earth between Sun and Moon would cause a lunar eclipse, which is when Earth blocks sunlight from reaching the Moon; the Moon simply orbiting Earth is normal motion and not an eclipse; Sun between Moon and Earth wouldn’t cast a shadow on Earth and thus isn’t an eclipse.
