Question

How the gravitational pull of the Sun and moon affect the tides?

Answer 1

When the sun and moon come in a straight line both(sun and moon) exert their force as a result high tide is generated.

While, if sun and moon come in right angle with respect to Earth a low tide is generated because sun and moon in this case try to neutralise the effect.

Answer 2

Answer:

Tides are periodic rising and falling of the sea level due to the gravitational pull of the Moon and Sun acting on the rotating Earth. Tides are of two types - High tides and low tides. During high tides, the waters rise in the tidal belt and rush in toward the land and flood it. During low tide, the water level falls and the sea water recedes. The sea level rises and falls once or twice per day because of tides action. Along most coastal area, the sea rises two times and falls two times a day. Areas that are alternately submerged and exposed by rising and falling tides are tidal flats
