Tides and Tidal stream Notes
The main cause of tides is the gravitational effect of the moon and sun on the Earth.
Spring Tides: High tides are at their highest, and low tides at their lowest. Its when the earth is in line with the moon and sun.
Spring tides follow seven days after Neap tides, then seven days later it is Neaps again.
Neap tides: Low tides are smaller than spring tides.Its when the earth, moon, and sun are not in alignment. Neap tides occur twice a month when the Sun and Moon are at right angles to the Earth.
