What are the factors responsible for tides? Desribe the conditions that lead to neap and spring tides
What will be an ideal response?
Tides are the twice-daily oscillations in sea level. Tides are produced by the gravitational pull of both the Sun and the Moon, though the Sun's influence is only about half that of the Moon's due to its greater distance from the Earth. This gravitational pull affects the Earth's atmosphere, oceans, and lithosphere. The stretching large tidal bulges. The Earth's surface rotates into and out of the tidal bulges as the Earth changes its position in relation to the moon and sun. Every 24 hours, 50 minutes, any given point on the Earth rotates through two bulges as a result of this rotational position. As a result, coastal locations experience two high (rising) tides and two low (falling) tides, called flood tides and ebb tides respectively. The difference between consecutive high and low tides is the tidal range. The range is greatest when the Earth, Sun, and Moon are in conjunction or in opposition. This is the spring tide. When the Earth, Sun, and Moon are neither in opposition or conjunction, there is less tidal range called the neap tide.
