The oceans change all the time. The tide rises up onto
the beach which we call a high tide and then recedes back into the ocean
which we call a low tide. This all seems to happen without any help from
somewhere but it is the moon that controls this phenomenon. How does this all happen ? Let’s have a look. When the Sun, Earth and moon line up in a straight
line, the combined gravity of the Sun and the moon have an effect on the
earth’s oceans, causing them to rise by as much as 15 meters. These very high
and low tides are called Spring tides and happen every two weeks. When the Sun, Earth and moon are perpendicular to each
other, their gravitational pulls cancel each other out resulting in weak high
and low tides. These tides are called Neap tides. |
