Question

question 3
what is an eclipse?
a. an event in which two penumbras overlap and create their own umbra
b. an event in which the shadow of one celestial object falls on another celestial object
c. an event in which the length of earths umbra causes all light to be blocked from reaching the moon
d. an event in which the umbra from one celestial object merges with the umbra of another celestial object

Explanation:

An eclipse occurs when the shadow of one celestial object falls on another. For example, in a solar eclipse, the Moon's shadow falls on Earth; in a lunar eclipse, the Earth's shadow falls on the Moon. Option A is incorrect as it misrepresents the nature of an eclipse. Option C only describes a specific type (lunar eclipse) rather than the general definition. Option D is also an incorrect description.

Answer:

B. an event in which the shadow of one celestial object falls on another celestial object
