Q1. High tides at antipodes are caused due to
(a) Gravitational pull of the moon and the sun
(b) Gravitational pull of the sun
(c) Centrifugal, centripetal and gravitational pull of the sun
(d) Centrifugal, centripetal and gravitational pull of the sun and the moon
(UPSC Prelims 1986)
Answer: (d) Centrifugal, centripetal and gravitational pull of the sun and the moon
Explanation: High tides occur due to the combined gravitational forces of the moon and the sun, along with centrifugal and centripetal forces acting on Earth’s oceans. These forces create bulges of water on opposite sides of the Earth, known as antipodal tides.
