Questions and Answers

What is the primary cause of tides in the Earth-moon-sun system?

Wind patterns across the oceans
Gravity from the moon and sun (correct)
Variations in ocean temperature
Earth's rotation on its axis

Why is it convenient to model the Earth as a spherical body uniformly covered with water when studying tides?

It reflects the actual shape of the Earth accurately.
It disregards the influence of landmasses on tides.
It allows for more complex tidal theories to be developed.
It simplifies the calculation of gravitational forces. (correct)

Which factors should be considered separately before analyzing their combined effects on tides?

Earth and oceans
Sun and wind
Moon and sun (correct)
Moon and stars

Study Notes

Tidal Theory

Tidal theory begins with a simplified model of Earth: a sphere covered entirely in water.
Tidal effects are studied individually for the Moon and the Sun, then combined to understand their interaction.
Tides are the result of gravitational forces within the Earth-Moon-Sun system.
The movement of these three celestial bodies influences the tides.
