Explain how spring and neap tides occur. What will be an ideal response?

---

The ocean responds simultaneously to inertia and to the gravitational force of both the sun
and moon. If Earth, moon, and sun are all in a line, the lunar and solar tides will be additive,
resulting in higher high tides and lower low tides. The large tides caused by the linear
alignment of the sun, Earth, and moon are called spring tides. During spring tides, high tides
are very high and low tides very low. These tides occur at 2-week intervals corresponding to the new and full moons. But if the moon, Earth, and sun form a right angle, the solar tide
will tend to diminish the lunar tide. Because the moon’s contribution is more than twice that
of the sun, the solar tide will not completely cancel the lunar tide. Neap tides occur when the
moon, Earth, and sun form a right angle. During neap tides, high tides are not very high and
low tides not very low. Neap tides also occur at 2-week intervals, with the neap tide arriving
a week after the spring tide
