According to Newton, which of the following statements about the Earth's tides is
FALSE?
a) High tides are highest at Full or New moon
b) High and low tides are due primarily to the Moon's gravitational pull on Earth's
oceans
c) Spring and neap tides are due to the combined gravitational pull of the Moon
and Sun on Earth's oceans

high tide is at its lowest - ....ANSWER ...-Neap tides are when the high tide
is at its highest and spring tides are when the high tide is at its lowest
