Why are tides stronger at the new moon for a few months and then it changes back to having tides stronger at the full moon?
Tides are caused by the gravitational pull of the moon and the sun on the Earth's oceans. The strength of this pull can vary depending on the relative positions of these celestial bodies, resulting in stronger or weaker tides at different times.
The shape and topography of the coastline and ocean floor can also affect the strength of tides at a particular location. Narrow channels and shallow areas can amplify the effect of tides, resulting in stronger tides at these locations.
During a full moon or new moon, the sun, moon, and Earth are in alignment, resulting in a stronger gravitational pull on the Earth's oceans. This is known as a spring tide and typically results in higher high tides and lower low tides.
The tilt of the Earth's axis and its orbit around the sun can also affect the strength of tides. During the summer and winter solstices, when the Earth is tilted towards or away from the sun, the difference between high and low tides is greater, resulting in stronger tides.
The gravitational pull of the moon is strongest on the side of the Earth facing the moon, which results in a bulge of water towards the moon. This is known as the tidal bulge and is responsible for the higher tides on this side of the Earth. The opposite side of the Earth also experiences a high tide due to the centrifugal force caused by the Earth's rotation.
