Questions Related to tides

The periodic rise and fall of water level in the ocean is called ___________.

geography tides movements of ocean and sea water circulation of ocean water ocean water movement

  1. waves

  2. tides

  3. water current

  4. turbidity currents

Show answer
Correct Option: B
Explanation:

The rise and fall of sea water due to gravitational forces of the sun and the moon are called tides. In fact, tides are the most uniformly varying phenomenon in the ocean. 

The summit of the wave is known as ____________.

  1. wave crest

  2. tidal range

  3. wave trough

  4. wave length

Show answer
Correct Option: A
Explanation:

Wave Crest is the point on a wave with the maximum value of upward displacement within a cycle. A crest is a point on a surface wave where the displacement of the medium is at a maximum.

 Area where wave tumble first is called ___________.

  1. surf

  2. breaker

  3. coast

  4. shore

Show answer
Correct Option: B
Explanation:
As the wave approaches the shore, it grows in height and steepness as the water gets more shallow. Ultimately, the waves grow to the point that the water isn't deep enough to support it. At this point, the wave topples, or breaks which result in a breaker. There are different types of breakers, but mainly there are two types:
Spilling breakers and plunging breakers.

The bottom part of the wave is known as ____________.

  1. wave crest

  2. wave trough

  3. wave length

  4. wave height

Show answer
Correct Option: B
Explanation:

A trough is the minimum or lowest point of the value of displacement within a cycle. 

The distance between two adjacent wave crests is called ____________.

  1. wave crest

  2. wave trough

  3. wave length

  4. wave height

Show answer
Correct Option: C
Explanation:

Wavelength is the distance between one crest or trough to the next crest or trough. It is the distance between identical points in the adjacent cycles if a waveform signal propagated in space or along a wire.

The vertical distance between the crest and trough of the wave is called the ____________.

  1. wave trough

  2. wave length

  3. crest period

  4. wave height

Show answer
Correct Option: D
Explanation:

Wave height is the distance between the crest and trough. The wave height of a surface wave is the difference between the elevations of a crest and a neighboring trough. Wave height is a term used by mariners, as well as in coastal, ocean and naval engineering.

As the speed of the wind increases, the strength of the wave ____________.

  1. increase

  2. decrease

  3. remains same

  4. became calm

Show answer
Correct Option: A
Explanation:

Waves in the sea surface are generated by the action of the wind. The height of the wind waves increases with the increasing wind speed and with increasing duration and fetch of the wind. As the speed of the wind increases, the strength of the wave also increases.

In the ocean, water moves horizontally over vast areas due to _____________.

  1. temperature difference

  2. density

  3. waves

  4. slope of ocean floor

Show answer
Correct Option: C
Explanation:

Waves are actually the energy, not the water as such, which moves across the ocean surface. Water particles only travel in a small circle as a wave passes. Wind provides energy to the waves. Wind causes waves to travel in the ocean and the energy is released on shorelines. Thus, it is due to waves only that water moves horizontally over vast areas.

Water waves are a manifestation of ______ moving through the ocean.

  1. Heat

  2. Density

  3. Energy

  4. Velocity

Beaches are formed due to the action of ________.

  1. tide

  2. current

  3. wave

  4. wind
