All changes in the weather are caused by the:

  1. Earth

  2. Sun

  3. Moon

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

The energy that the Earth receives from the Sun is the basic cause of our changing weather. Solar heat warms the huge air masses that comprise large and small weather systems.However, at higher altitudes, the atmosphere reacts strongly to changes in solar activity.

Multiple choice physics primary concept of force and energy contact and non-contact forces comparing force in magnetic, electric and gravitational fields identifying forces

Does moon have its own gravity?

  1. No

  2. Yes

  3. Not known yet

  4. Only during full moon
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Gravity is not a property of the earth alone. Every object in the universe exerts a force on every other object. This is called gravitational force. Naturally, moon also has its own gravity.

Mention the sequence of the position of the sun, earth, and moon in lunar eclipse.

  1. Sun, Earth, Moon

  2. Earth, Moon, Sun

  3. Moon, Sun, Earth

  4. Sun, Moon, Earth
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.

The spring tide occurs when the moon, the sun and the earth make in angle of _______.

  1. $180^o$
  2. $90^o$
  3. $45^o$
  4. $33^o$
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The spring tide occurs when the moon, the sun and the earth make in angle of $180^0$.

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. During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other.

Neap tides are produced in the first and third quarters of the moon. Then _______.

  1. Moon and the Sun are in conjunction with the other planets

  2. Moon and the Sun are in opposition with each other

  3. The attractions of the Sun and the Moon are at right angles to each other

  4. The Moon and Sun are in quadrant position to each other

C Correct answer
Explanation

Neap tides are produced in the first and third quarters of the moon. Then the attractions of the Sun and the Moon are at right angles to each other.

Neap Tides
During the moon's quarter phases the sun and moon work at right angles, causing the bulges to cancel each other. The result is a smaller difference between high and low tides and is known as a neap tide. Neap tides are weak tides.

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.

On new moon and full moon days _______ occurs.

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.

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.

What are known as Spring Tides?

  1. When sun and moon are aligned causes strong high and low tides

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

  3. When sun and moon are aligned causes only low tides

  4. When sun and moon are not aligned causes only high tides

A Correct answer
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.
