Explains ocean tides by balancing forces like gravity and inertia.

Includes gravitational force from the moon and centrifugal force from Earth’s rotation.

Condition where two bodies maintain their position due to balanced forces.

The moon's gravity pulls the ocean, creating tides towards it.

The resistance of any physical object to any change in its velocity.

The point where two celestial bodies balance each other's gravitational pull.

Two raised areas of ocean water caused by the moon's gravity and Earth's tendency to whirl.

The combination of gravitational pull and centrifugal force acting on the oceans.

A model explaining tidal movements based on Earth's rotation and moon's position.

A complete tidal day lasts 24 hours and 50 minutes due to the moon's movement.

The moon's position varies, causing bulges to shift relative to the equator.

Tides influenced primarily by the moon's gravitational pull.

Tides caused by the sun's gravitational pull, weaker than lunar tides.

High tides occur at bulges; low tides at troughs between them.

Theoretical wavelength of tide waves can reach 20,000 km.

Tides caused by the gravitational force from the sun and moon together.

Occurs when the Earth, moon, and sun align, resulting in higher high tides and lower low tides.

Occurs when the moon, Earth, and sun form a right angle, resulting in less extreme tides.

The gravitational influence causing tides, inversely proportional to the cube of the distance between two bodies.

The position where the moon is closest to Earth in its orbit.

The position where the moon is farthest from Earth in its orbit.

The period it takes for the moon to complete one rotation relative to the Earth, which is about 24 hours and 50.47 minutes.

The period of one complete rotation of Earth on its axis, approximately 24 hours.

The angle of Earth's axis relative to its orbit, approximately 23.45°.

The plane of Earth's orbit around the Sun.

The angle of the Moon's orbit relative to the ecliptic, varying between ±5.15°.

The rise in water level due to gravitational pull from the Moon and Sun.

A basic model predicting tidal behavior assuming a calm ocean without landmass interference.

Tidal pattern with two high and two low tides each lunar day.

The points in ocean basins where tidal crests do not rotate, affecting local tide height.

Tide pattern featuring variations in height between successive high or low tides.

The flow of water caused by the rise and fall of tide crests in bays and harbors.

Water that rushes into an area as tide crests rise.

Water that flows out as tide troughs approach, causing a drop in sea level.

A period with no tidal current, occurring at high and low tides.

Components that make up total tides, characterized by amplitude, phase, and period.

Lunar and solar tides characterized by periods of 12.42 h and 12 h, respectively.

Influence of atmospheric conditions on sea levels, especially near shore.

Rise in sea level due to low atmospheric pressure and strong winds.

Tides dissipate ~3.75 TW of power, affecting Earth's rotation.

Tidal friction gradually decreases Earth's rotation speed.

The moon's rotation is locked to its orbit around Earth, showing one side to us.

Area between high-tide and low-tide marks with unique organisms.

Different bands in the intertidal zone where organisms live adapted to specific conditions.

Generating electricity from trapped high-tide water as an alternative energy source.
