Penyebab pasang surut air laut

Summary

Tides are natural phenomena where the sea level rises and falls regularly, caused by the gravitational pull of the Moon and the Sun on Earth's waters. Despite the Sun being larger than the Moon, the Moon's closer proximity results in a stronger gravitational effect, making it the primary cause of tides. Tides can be categorized into spring tides, occurring during the new and full moon phases, when the Sun, Earth, and Moon align, and neap tides, which happen when the Sun and Moon form a 90-degree angle, leading to less extreme tidal changes.

Takeaways

• 😀 Tides are natural phenomena where the surface of the sea rises and falls regularly and repeatedly.
• 😀 High tide (pasang) occurs when the sea level is higher than usual, while low tide (surut) occurs when the sea level is lower than usual.
• 😀 Tides are primarily caused by the gravitational pull of the Sun, Earth, and Moon, with other celestial bodies having minimal influence.
• 😀 Despite the Sun's larger size, the Moon's gravitational pull has a greater effect on tides, being twice as strong due to its closer proximity to Earth.
• 😀 Water is easily influenced by gravitational forces, causing changes in sea surface levels when affected by the Moon and Sun.
• 😀 The height of tides varies by location due to different levels of gravitational pull from the Moon and Sun.
• 😀 Tides are classified into two types: spring tides (pasang purnama) and neap tides (pasang perbani).
• 😀 Spring tides (pasang purnama) occur twice a month, during new and full moons, when the Sun, Earth, and Moon align.
• 😀 During spring tides, the water level in areas experiencing high tide reaches its highest point, while areas at low tide experience their lowest levels.
• 😀 Neap tides (pasang perbani) occur when the Sun, Earth, and Moon form a 90-degree angle, resulting in less extreme tidal changes.
• 😀 During neap tides, the high tide is not as high and the low tide is not as low, as the gravitational forces of the Moon and Sun partially cancel each other out.

Q & A

What is the definition of pasang surut (tide)?

Pasang surut is a natural phenomenon where the surface of seawater rises and falls in a regular and repetitive pattern.

What happens during high tide (pasang)?

During high tide (pasang), the seawater level rises above its usual level.

What occurs during low tide (surut)?

During low tide (surut), the seawater level decreases and is lower than usual.

What causes the pasang surut phenomenon?

Pasang surut is caused by the gravitational forces between the Earth, Moon, and Sun. The Moon's gravity has the greatest effect, despite its smaller size compared to the Sun.

Why is the Moon's gravity stronger in influencing tides compared to the Sun's?

The Moon's gravity is stronger in influencing tides because the Moon is much closer to Earth than the Sun, even though the Sun is larger.

How does the gravitational pull of the Moon affect seawater?

The gravitational pull of the Moon causes the seawater to experience varying heights, resulting in the rise and fall of tides.

What are the two types of tidal events mentioned in the script?

The two types of tidal events are pasang purnama (spring tide) and pasang perbani (neap tide).

When does pasang purnama (spring tide) occur?

Pasang purnama occurs twice a month, during the new moon and full moon phases, when the Earth, Moon, and Sun align.

What happens during pasang purnama in terms of seawater levels?

During pasang purnama, the areas experiencing high tide will have the highest water levels, while areas at low tide will have the lowest water levels.

When does pasang perbani (neap tide) occur, and how does it affect the tides?

Pasang perbani occurs when the Earth, Moon, and Sun form a 90-degree angle. This results in moderate tidal fluctuations, with high tides not reaching extreme levels and low tides not being as low as usual.
