Tides Review

What is a high tide?

• The minimum level of the sea during the tidal cycle.

• The maximum level of the sea reached during the tidal cycle, caused by the gravitational pull of the moon and the sun.

• A phenomenon that occurs only during a full moon.

• The average sea level over a month.

What is the gravitational pull?

• The force exerted by a celestial body that affects the movement of water in the oceans.

• A type of magnetic force that attracts objects towards each other.

• The force that keeps planets in orbit around the sun.

• The push that objects experience when they are thrown into the air.

What causes tides?

• The gravitational forces exerted by the moon and the sun on the Earth's oceans.

• The rotation of the Earth on its axis.

• The wind patterns across the oceans.

• The temperature differences in ocean water.

What is a low tide?

• The maximum level of the sea reached during the tidal cycle.

• The minimum level of the sea reached during the tidal cycle, occurring between high tides.

• A phenomenon that occurs only during a full moon.

• The average sea level over a month.

What is a spring tide?

• A tide that occurs when the moon is either new or full, resulting in the highest high tides and the lowest low tides.

• A tide that occurs only during the summer months.

• A tide that is caused by the gravitational pull of the sun only.

• A tide that occurs when the moon is in its first quarter phase.

What is the tidal range?

• The distance between the shore and the ocean floor.

• The difference in height between high tide and low tide.

• The speed at which tides move in and out.

• The area of land affected by tidal movements.

What is the effect of the sun on tides?

• The sun has no effect on tides.

• The sun exerts a gravitational pull on the Earth's oceans, affecting the height and timing of tides, but its effect is less than that of the moon.

• The sun causes tides to be higher than the moon.

• The sun only affects tides during the summer months.

What is a tidal cycle?

• A phenomenon that occurs every 24 hours and 50 minutes.

• A regular rise and fall of sea levels, typically occurring every 12 hours and 25 minutes.

• An irregular fluctuation of sea levels caused by weather patterns.

• A cycle that only occurs during full moons.

What is the relationship between the moon's phases and tides?

• The moon's phases have no effect on tides.

• Tides are highest during the first quarter moon.

• Spring tides occur during full and new moons, while neap tides occur during first and third quarters.

• Tides are only influenced by the sun's position.

What happens to the water level during low tide?

• The water level rises, covering more of the beach.

• The water level remains the same throughout the day.

• During low tide, the water level falls, exposing more of the beach and shoreline.

• The water level fluctuates randomly without a pattern.
