QuestionAnswer
What are tides influenced by? The gravity of the moon and the sun.
How often tides occur and how tidal levels vary depend on... The position of the moon as it revolves around earth.
What part of the earth is the moon's pull strongest on? The part of the Earth that directly faces the moon.
When does water bulge? When a part of the ocean faces the moon.
What's another word for bulges? High tides.
High tides draw water away from the area between the high tides and cause... Low tides to form in those areas.
What are tides determined by? Earth's rotation and the moon's revolution around earth.
Why doesn't the moon always have the same position in relation to the Earth? Because the speed at which the moon revolves around earth is too slow.
Why is the sun's influence on tides less powerful than the moon's? Because the sun is much larger than the moon, and also much farther from earth than the moon is.
What do the combined forces of the sun and moon on earth cause? Tidal ranges that vary based on the positions of all 3 bodies.
When do spring tides occur? When the sun, moon, and earth are aligned, when the moon is between the sun and the earth, or when the sun and the moon are on opposite sides of earth.
When do neap tides occur? When sun, earth, and moon form a 90 degree angle, half way between spring tide occurrences, and when forces of the sun and moon work against each other on earth.
Where do tidal bores occur? In coastal areas with narrow inlets.
What are the 4 types of tides? Spring tides, neap tides, high tides, and low tides.
Tide The periodic rise an d fall of the water level in the oceans and other large bodies of water
Tidal range The difference in levels of ocean water at high tide and low tide.
Spring tide A tide of increased range that occurs two times a month, at the new and full moons.
Neap tide A tide of minimum range that occurs during the first and third quarters of the moon.
Tidal Bore A body of water that rushes up through a narrow bay,estuary, or river channel, during the rise of high tide and causes a sudden tidal rise.
