Question

Which description explains why there are two neap tides per month? Earth rotates in and out of a tidal bulge created by gravitational forces. Earth moves closer to the sun and moon twice a month. The moon and sun are at a 90-degree angle to Earth twice a month. The moon, sun, and Earth are aligned twice a month.

Answer 1

The moon and sun are at a 90-degree angle to Earth twice a month.

Its correct :)

Answer 2

There are two neap tides per month because:

The moon and sun are at a 90-degree angle to Earth twice a month.

Neap tides are also known as moderate tides. The lunar tide is partially cancelled when the moon and the sun are at a 90-degree angle to Earth, or being at right angles. This event happens twice a month thus creating neap tides twice a month also.
