Flashcards
Equilibrium Theory
Equilibrium Theory
Describes tides based on the position and gravitational attraction of the Earth, moon, and sun, ignoring ocean depth and landmasses.
Dynamic Theory
Dynamic Theory
Considers factors like shallow water, continents, and water movement to explain tidal patterns more accurately than equilibrium theory.
Tidal Potential
Tidal Potential
The gravitational force from the moon and sun that influences the rise and fall of tides.

Study Notes
Equilibrium Theory
- Primarily focuses on the Earth, Moon, and Sun's positions and gravitational forces.
- Ignores ocean depth and continental landmasses' influence.
- Accurately predicts tides on a completely water-covered planet.
- Assumes a flat, uniform ocean surface constantly in equilibrium with gravitational pulls.
- Simplified model of tides, overlooking the complexities of real-world oceans.
Dynamic Theory
- Considers factors like the tide wave's speed in shallow water.
- Acknowledges the effects of continents and water movement in basins.
- Takes into account the circular or rocking motion of ocean water.
- Derives tidal potential from the moon and sun's gravitational pull.
- Aims to provide a more realistic representation of ocean tides.
- Explains tides in terms of gravitational forces and ocean dynamics.
