How does the Moon generate tides? Why are there generally two high tides and two low tides a day? What will be an ideal response?
The gravitational pull of the Moon on Earth pulls the water toward it, creating a bulge at the nearest
point. Another bulge forms on the opposite side of Earth due to the centrifugal force of Earth's
rotation. These two bulges point toward and away from the Moon, and between the two bulges are two
troughs since the water is in the bulges. The bulges are high tides, and the troughs are low tides. Earth
rotates beneath them, and most shorelines on Earth reach each one once a day, and so have two high
tides and two low tides each day.
