(ii) The water cycle is the continuous movement of water between the oceans, land, and atmosphere through processes like evaporation, condensation, and precipitation.

(iii) The height of ocean waves is mainly affected by the speed of the wind, the duration of the wind, and the distance over which the wind blows.

(iv) The movement of ocean water is influenced by winds, temperature differences, the rotation of the Earth, and the gravitational pull of the Sun and the Moon.

(v) Tides are the regular rise and fall of ocean water. They are mainly caused by the gravitational pull of the Moon and the Sun on the Earth.

(vi) Ocean currents are large streams of ocean water that flow in fixed directions across the oceans.
