Explanation:
Ocean movements involving the rhythmic rise and fall of ocean water twice a day are known as tides. Tides are primarily caused by the gravitational pull of the moon and the sun on the Earth's oceans.
Factors influencing tides:
- Moon: The gravitational pull of the moon is the main factor responsible for causing tides. The moon's gravitational force pulls the water towards it, causing a bulge of water on the side of the Earth facing the moon.
- Sun: Although the sun's gravitational pull is weaker than the moon's, it also contributes to the tides. When the sun, moon, and Earth are aligned, the gravitational forces of the sun and moon combine, leading to higher high tides known as spring tides.
- Earth's rotation: The rotation of the Earth also influences tides. As the Earth rotates on its axis, different parts of the oceans are exposed to the gravitational forces of the moon and the sun, leading to the rise and fall of tides.
Types of tides:
- High tide: This is when the water reaches its highest level, covering more of the shore.
- Low tide: This is when the water reaches its lowest level, exposing more of the shore.
Frequency of tides:
- Tides occur approximately every 12 hours and 25 minutes, with two high tides and two low tides each day.
In conclusion, tides are the rhythmic movements of ocean water caused by the gravitational forces of the moon and the sun, leading to the rise and fall of water levels along the shorelines.
