During full moon _________ tides occur.

  1. neap

  2. spring

  3. high

  4. low
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When the moon is full or new, the gravitational pull of the moon and sun are combined. At these times, the high tides are very high and the low tides are very low. This is known as a spring high tide. Spring tides are especially strong tides (they do not have anything to do with the season Spring). They occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.

The movement of the ocean water which is used for producing salt is _______.

  1. Waves

  2. Warm current's

  3. Cold currents

  4. Tides

D Correct answer
Explanation

In cold countries, tides bring in saltwater and by their constant motion prevent harbours from becoming icebound. Low-lying areas along the sea-coast which get the seawater during high tides can be used to produce salt by trapping the water.

When the earth and the sun are in a straight line and the moon is at right angle to the earth, the _________ tide occurs.

  1. high tide

  2. low tide

  3. spring tide

  4. neap tide
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Seven days after a spring tide, the sun and moon are at right angles to each other. When this happens, the bulge of the ocean caused by the sun partially cancels out the bulge of the ocean caused by the moon. This produces moderate tides known as neap tides, meaning that high tides are a little lower and low tides are a little higher than average. Neap tides occur during the first and third quarter moon, when the moon appears "half full."

What type of tide occur when the sun, moon and the earth are in the right angle?

  1. Spring tide

  2. Neap tide

  3. Low tide

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

Neap tides occur when the Moon and Sun form a right angle with the Earth. In contrast to spring tides, neap tides are the effect of tidal forces canceling each other.

The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are especially weak tides. They occur when the gravitational forces of the Moon and the Sun are perpendicular to one another (with respect to the Earth). Neap tides occur during quarter moons.

The rise in the level of ocean water is called ____________.

  1. High tide

  2. Low tide

  3. Neap tide

  4. Spring tide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Tides are caused by the moon. The tidal force causes Earth and its water to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides. It is because of high tides only that the sea level rises.

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
Reveal answer Fill a bubble to check yourself
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.
