Spring Tides refer to either of the two tides that occur at or just after new moon and full moon when the tide-generating force of the sun acts in the same direction as that of the moon, reinforcing it and causing the greatest rise and fall in tidal level. The highest spring tides (equinoctial springs) occur at the equinoxes.

Correct Option: B

The word ‘Kuroshio’ means ‘Black Current’ in Japanese. Also known as Japan Current, it is a warm ocean current which flows up the East coast of Asia and under the influence of the westerly winds to wards North America. It is the counterpart of the Gulf Stream. However, the Antarctic Circumpolar Current is the largest oceanic current on Earth.

At 165.25 million square kilometers in area, the Pacific Ocean is the largest division of the World Ocean – and, in turn, the hydrosphere. It covers about 46% of the Earth’s water surface and about one-third of its total surface area, making it larger than all of the Earth’s land area combined.

Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.

The rhythmic rise and fall of ocean water twice in a day is called a tide. The tides are caused due to strong gravitational pull exerted by the sun and the moon on the earth’s surface.
