Question

The up and down motion of the water along the surface of the sea is called___
a) Tide
b) Current
c) Waves
d) Ebb

Answer 1

Hint: Seas are smaller than seas in geological terms and are usually situated where the land and the ocean meet. The seas are usually partly surrounded by land. On the margins of the ocean, seas are located and are partly surrounded by shore. Seas are smaller than oceans and where the land and ocean intersect, they are generally situated.

Complete Answer:
- Waves are nothing but oscillatory motions that contribute to the surface of the water rising and dropping. Waves are a type of horizontal ocean water movement.
- Actually, they are the force that travels through the surface of the ocean, not the water as such. This energy is provided by the wind for the waves. The movement of each water molecule in a wave is in a circular way. There are two main parts of a wave: the high portion is called the crest, while the low point is called the trough.
- In response to the forces exerted by the moon and sun, tides are very long-period waves which move through the oceans. Ocean currents, abiotic features of the environment, are constant and guided motions of ocean water. Tides originate in the seas and advance towards the coastlines where they manifest as the normal rise and fall of the sea surface.
- When the tide drains away from the shore, the Ebb is the outgoing stage; and when the water rises again the flow is the incoming phase. In figurative use the words are also popular.

Hence, the correct answer is option c).

Note: A position in the tidal range is also played by the Moon phase. The solar tide coincides with the lunar tide during these phases of the Moon, since the Sun and the Moon are aligned with Earth, and their gravitational forces combine to pull the water of the ocean in the same direction. These tides are known as the tides of the spring or the king.
