When does spring tides occur?

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. During full moon and new moon

  2. During quarter moon

  3. Only during full moon

  4. Only during new moon

Show answer
Correct Option: A
Explanation:

Tide with the greatest difference between the high and low tide, that occurs just after a new or full moon is a spring tide.

Offshore, in the deep ocean the difference in tides is usually less than: 

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. 1.5 feet

  2. 1.6 feet

  3. 1.4 feet

  4. 1.3 feet

Show answer
Correct Option: B
Explanation:

Offshore in the deep ocean the difference in tides is usually less than 1.6 feet. The highest tides can however have a range of 44.6 feet, observed in the Bay of Fundy, Canada.

Tides are not caused by the direct pull of the moon's gravity. Is the statement true or False

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Tides are the result of the gravitation pull of the Moon on the Earth's water body.


Spring tides are especially strong tides. Is statement true or false

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. True

  2. False

Show answer
Correct Option: B
Explanation:

Tide with the greatest difference between the high and low tide, that occurs just after a new or full moon is a spring tide.

Hence, these tides are the strongest tides.

What are known as tides?

  1. Alternating rise and fall in sea level with respect to land

  2. Alternating rise in sea level with respect to land

  3. Alternating fall in sea level with respect to land

  4. None

Show answer
Correct Option: A
Explanation:

Rise and fall of the surface of the Earth's water body due to the gravitation pull of the Moon and the Sun on the Earth is tides.

Which tides occur when gravitational forces of Moon and Sun are perpendicular to one another?

  1. Spring Tides

  2. Neap Tides

  3. Monsoon Tides

  4. Summer Tides

Show answer
Correct Option: B
Explanation:

Neap tides occur twice a month when the Sun and Moon make a angle of 90 degree with the Earth. Such tides are the weakest tides.

When does neap tides occur?

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. During quarter moons

  2. During full moons

  3. During new moons

  4. During half moons

Show answer
Correct Option: A
Explanation:

Neap tides are the tides with the least difference between the high and low tide. Neap tides occur just after the first or third quarters of the Moon.

What are known as neap tides?

physics gravitation tides movements of ocean and sea water circulation of ocean water

  1. When sun and moon are not aligned tides are not as high and low

  2. When sun and moon are aligned tides are not as high and low

  3. When sun and moon are not aligned tides are as high and low

  4. None

Show answer
Correct Option: A
Explanation:

Tide where the difference between the high tide and low tide is the least is called a neap tide. Such tides occur when the Sun and the Moon are in a right angled position with the Earth. This happens twice in a month.

The type of Gravitational Force that causes tides is known as:

  1. Nuclear Force

  2. Tractive Force

  3. Tidal Force

  4. Wave Force

Show answer
Correct Option: B
Explanation:

Tides are caused by the combined gravitation attraction of the Sun and Moon on the Earth. Force that results in a motion between a body and a tangential surface is called a tractive force.

The main cause of tides in an ocean is the gravitational pull of:

  1. Moon

  2. Sun

  3. Saturn

  4. Mars

Show answer
Correct Option: A
Explanation:

The main cause of tides in an ocean is the gravitational pull of the Moon on the Earth.
