tides are produced by the gravitational pull of the moon and the sound
as the moon orbits the earth, high tides follow it
the moon pulls water towards it - opposite budge on each side of earth
2
Q
when does the highest tide occur
A
when the moon and the sun are aligned - as gravitational pull is at its strongest
happens twice a month results in spring tides
3
Q
when are the lowest tides
A
twice a month when the moon and sun are at right angles to each other
gravitational pull is at its weakest
produces neap tides with low range
4
Q
where are tidal ranges low
A
in enclosed seas - as wave action is restricted to a narrow area of land
5
Q
where are tidal ranges higher
A
in places where the coast is funnelled - estuaries
