Which of the following reason are responsible for the formation of tides?

  1. Tides are formed as a result of the gravitational pull exerted by the moon.

  2. Tides are formed as a result of the gravitational pull exerted by the sun

  3. Tides are formed as a result of the centrifugal force due to the earth's rotation

  4. All of the above

D Correct answer
Explanation

Tides are caused by the gravitational pull of the moon, the gravitational pull of the sun, and the centrifugal force generated by the Earth's rotation.

Tides which occur in the new moon and full moon days is called ________.

  1. neap tide

  2. spring tide

  3. low tide

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Very high tide is caused when the sun, the moon and the earth are almost in the same line. Such high tides are called spring tides. During new moon and full moon the gravitational forces of sun and the moon work together with combined force and thus this spring tide occurs.

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.
