the ocean surface at a particlar place
Tides
TERM 2
caused by the gravitational force of the moon
and sun and the motion of earth
DEFINITION 2
tides
TERM 3
are forced waves because they are never free
of the forces that cause them
DEFINITION 3
tides
TERM 4
are created by the position of the earth,
moon, and sun

dynamictheory of tides
TERM 25
move as fored waves with their velocity
determined by ocean depth, they behave as
shallow water waves

tidal currents
TERM 34
a time of no currents, occurs at high and low
tides when the current changes directions
