"Relate the positions of the moon and sun to their effect on ocean tides."
Tides are caused by the gravitational pull of the Moon and Sun on Earth. Spring and Neap Tides cause the ocean's water level to rise and fall. The type of tide changes with the Moon's orbit.
Understanding Spring and Neap Tides
Spring Tide: A time when the Moon is closest to the Earth resulting in a greater than average difference between high and low tides. Neap Tide: A time when the Moon is furthest from Earth resulting in a smaller than average difference between high and low tides. Gravitational Pull: The force of attraction between two objects, such as the Moon and Earth, caused by their masses.
In which month do Spring and Neap Tides occur?
The Moon orbits the Earth every 27.3 days. Tidal ranges can differ from one day to the next. The highest tides occur during full and new moons.
