Match List-I with List-II and select the answer using the codes given below the Lists: List-I (Type of Tide) A. Spring Tides B. Neap Tides C. Apogean Tides D. Equinoctial Spring Tides List-II (Characteristic) 1. Low tides caused when the Sun, Earth and Moon are in the position of quadrature 2. Occur when the Moon is the farthest from the Earth 3. Tides recurring at an interval of six months 4. Very high tides caused when the Sun, Moon and Earth are almost in the same line Codes: (a) 3 1 2 4 (b) 3 2 1 4 (c) 4 2 1 3 (d) 4 1 2 3

The correct matching is as follows:

• Spring Tides (A-4): These occur when the Sun, Moon, and Earth are aligned in a straight line (syzygy), resulting in the highest high tides due to combined gravitational pull.
• Neap Tides (B-1): These occur when the Sun and Moon are at right angles (quadrature) to the Earth, causing the gravitational forces to partially cancel out, leading to lower tidal ranges.
• Apogean Tides (C-2): These occur when the Moon is at its farthest point from the Earth (apogee), resulting in weaker gravitational pull and lower tides than average.
• Equinoctial Spring Tides (D-3): These occur during the equinoxes (March and September), recurring at six-month intervals when the Sun is directly over the equator, enhancing the tidal effect.

Thus, the correct sequence is 4-1-2-3, which corresponds to option D.
