What is the time interval of every high and low tide?

  1. 5 hour 25 minutes

  2. 6 hours 25 minutes

  3. 10 hour 25 minutes

  4. 12 hour 25 minutes
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

On an average, every place experiences high and low tide a day at an time interval of 12 hours 25 minutes. Since the earth completes its rotation in roughly 24 hours, every place should experience tide after 12 hours but this never happens. Each day tide delayed by 25 minutes because the moon also rotates on its axis while revolving around the earth.

 Area where wave tumble first is called ___________.

  1. surf

  2. breaker

  3. coast

  4. shore
Reveal answer Fill a bubble to check yourself
B Correct answer
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 distance between two adjacent wave crests is called ____________.

  1. wave crest

  2. wave trough

  3. wave length

  4. wave height
Reveal answer Fill a bubble to check yourself
C Correct answer
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
Reveal answer Fill a bubble to check yourself
D Correct answer
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
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
