Match the following tides related terms with their correct definitions:

Tides = The rise and fall of sea levels caused by the gravitational forces between the Earth, Moon, and Sun High Tides = The state of the tide when at its highest level Low Tides = The state of the tide when at its lowest level Tidal Cycle = The time it takes for a tide to go from high to low and then back to high again Signup and view all the answers

Match the following factors with their effect on tides:

Moon = The primary factor that causes tides on Earth Sun = The secondary factor that also contributes to tides on Earth Gravitational Forces = The forces that cause the water on Earth to bulge out in the direction of the Moon Rotation of the Earth = The factor that causes two high tides and two low tides every lunar day Signup and view all the answers

Match the following tidal patterns with their descriptions:

Diurnal Tides = A tidal pattern with one high tide and one low tide each lunar day Semi-diurnal Tides = A tidal pattern with two high tides and two low tides each lunar day Mixed Tides = A tidal pattern with varying high and low tides each lunar day Spring Tides = A type of tide that occurs when the Sun, Moon, and Earth are nearly aligned, resulting in the greatest tidal range Signup and view all the answers

Study Notes

Tides

High tides are caused by the gravitational pull of the Moon and the Sun on the Earth's oceans.

Factors Affecting Tides

The gravitational pull of the Moon and the Sun
The Earth's rotation
The shape and size of the ocean basins
Wind and atmospheric pressure

Tidal Cycle

The average duration of a tidal cycle is 24 hours and 50 minutes.

Spring Tide: a tide with the greatest difference between high and low water levels, occurring when the Moon and Sun are aligned.
Neap Tide: a tide with the least difference between high and low water levels, occurring when the Moon and Sun are at right angles to each other.

Factors and Their Effects on Tides

Gravitational Pull of the Moon: causes the ocean water to bulge, resulting in high tides
Gravitational Pull of the Sun: enhances or cancels out the effect of the Moon's gravitational pull, depending on their alignment
Earth's Rotation: causes the tidal bulge to move around the Earth, resulting in high and low tides

Tidal Patterns and Descriptions

Diurnal Tide: a tidal pattern with one high and one low tide per day
Semidiurnal Tide: a tidal pattern with two high and two low tides per day
