Question

Which event(s) occur because the Earth, Moon, & Sun have a 180° alignment (straight angle)?

Answer 1

Answer:

Explanation:

The last total eclipse in the U.S. was in 1979. And the last total solar eclipse that crossed the entire continental U.S. happened in 1918. But why? Why has it been 99 years, and why have the intervening partial and even total eclipses caught only parts of the country?

Not sure if its 100% correct but it's similar to that I think

Answer 2

Answer:

When the earth, moon, and sun align, an eclipse forms.

Explanation:

The moon, sun, and earth can have a point in time where they perfectly align in a 180 degree alignment, or a straight angle, and that is what is called an eclipse. Depending on where the earth or moon is placed shows whether the eclipse is solar or lunar. For example, if in the alignment, the moon was in the middle of the three, it would be a solar eclipse. If the earth was in the middle of the three, then it would be a lunar eclipse.
