Question

Differentiate between spring tides and neap tides.

Answer 1

S.no.	Spring Tides	Neap Tides
1.	It occurs twice each month new moon day because the sun, moon and earth are in the straight line.	They occur at first and third quarter of the moon. Because during these days the sun, moon form a right angle with each other.
2.	When the rise and fall is more than the normal then it is called the spring tides.	The rise and the fall is considerably low than the normal level.
3.	It is due to complimentary gravitational effect and cause sun, moon and earth are in the same.	Here the tidal forces do not supplement each other because the moon and earth are in right angles and so the velocity of tidal current slows down.
