Tides occur in oceans and seas due to which of the following?

Gravitational Force of the Sun Gravitational Force of the Moon Gravitational Force of the Earth

Select the correct answer using the code given below

C.1 and 3 only
D.1, 2, and 3
B.2 and 3 only
A.2 only

Correct Answer: Option D

Tides are the periodic rise and fall of sea levels.

They are caused by the combined effects of:

  1. Gravitational forces exerted by the Sun
  2. Gravitational forces exerted by the Moon
  3. Rotation of the Earth.

The specific timing and amplitude of tides at any location are also influenced by the alignment of the Sun and Moon, patterns of tides in the deep ocean (amphidromic systems), and the shape of the coastline (near-shore bathymetry).

Therefore, all three statements are correct.
