Question

What type of tide occurs when the sun, moon and the earth are in the right angle?
A. Spring tide
B. Neap tide
C. Low tide
D. None of the above

Answer 1

Hint:- The gravitational pull of the sun, moon and the earth and the centrifugal force due to the rotation of the earth leads to the formation of tides and the change in the position of the sun and the moon with respect to the earth, leading to the change in nature and magnitude of the tide.

Complete answer:
Tides - rise and fall of the seawater as long-period waves because of the gravitational pull of both sun and the moon and the forces of the earth i.e. centrifugal force and gravitational force is called a tide.

Types of tides based on the position of sun, moon and earth -
Spring Tides:- When the sun, moon and the earth are located on a straight line with respect to each other than spring tides are formed. A spring tide occurs when there is a full moon period and when there is a new moon period i.e. two times in a month. They rise for a greater height.
Neap Tides:- when the sun and moon are aligned at right angles to each other then Neap Tides are formed. As in this situation the forces of both the sun and the moon act in the opposite direction to each other thus this results in the formation of tides of low magnitude.

Hence the correct answer is option B.

Note:- Bay of Fundy, located on the eastern margins of North America, and separating New Brunswick from Nova Scotia, experiences the highest tides of the world because of the funnelling effect due to its shape.
- Once a month, exceptionally high and low tides occur while the moon's orbit is nearest to the earth (perigee). The tidal range is higher than average during this span of time.
