Question

Twice each each lunar month, all year long, these tides occur. Whenever the Moon, Earth and Sun are aligned, the gravitational pull of the sun _____ to that of the moon causing _____ tides. A) adds; neap B) adds; maximum C) interferes; neap D) interferes; minimum

Answer 1

Hi there!

Twice each lunar month, all year long, these tides occur. Whenever the Moon, Earth, and Sun are aligned, the gravitational pull of the sun A. Adds to that of the moon causing A. Neap tides.

As a result of the extra gravity lent by the sun to the moon, it's pull is strengthened causing what we know as Neap tides.

Hope this helps!

Answer 2

That was a lucky pick.

Twice each each lunar month, all year long, whenever the Moon,
Earth and Sun are aligned, the gravitational pull of the sun adds
to that of the moon causing maximum tides.

This is the setup at both New Moon and Full Moon.  It doesn't matter
whether the Sun and Moon are both on the same side of the Earth,
or one on each side.  As long as all three bodies are lined up, we
get the biggest tides.

These are called "spring tides", when there is the greatest difference
between high and low tide.

At First Quarter and Third Quarter, when the sun, Earth, and Moon form a
right angle, there is the least difference between high and low tide.  Then
they're called "neap tides".
