A Correct answer
Explanation

Seismic waves are waves of energy that travel through the Earth's layers, and are a result of an Earthquake or a volcano that imparts low-frequency acoustic energy.

B Correct answer
Explanation

The Richter magnitude scale (also Richter scale) assigns a magnitude number to quantify the size of an earthquake.

An electroscope is an early scientific instrument that is used to detect the presence and magnitude of electric charge on a body. It was the first electrical measuring instrument. The first electroscope, a pivoted needle called the versorium, was invented by British physician William Gilbert around 1600.

Amber is fossilized tree resin, which has been appreciated for its colour and natural beauty since Neolithic times. Much valued from antiquity to the present as a gemstone, amber is made into a variety of decorative objects. Amber is used as an ingredient in perfumes, as a healing agent in folk medicine, and as jewellery.

An electric current is a flow of electric charge. In electric circuits this charge is often carried by moving electrons in a wire. It can also be carried by ions in an electrolyte, or by both ions and electrons such as in an ionised gas (plasma).

Seismic waves that vibrate perpendicular to the direction of their path _______.

  1. Travel through the solid parts of the earth only

  2. Travel through the solid as well as other parts of the earth

  3. Spread on the surface of the earth

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Seismic waves that vibrate perpendicular to the direction of travel are S-waves (secondary waves). S-waves are shear waves and cannot travel through liquids, meaning they only travel through the solid parts of the Earth.

The magnitude of the earthquake is measured on the ______________.

  1. Wind vane

  2. Barometre

  3. Richter scale

  4. Weighing scale
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The Richter scale was originally devised to measure the magnitude of earthquakes of moderate size (that is, magnitude 3 to magnitude 7) by assigning a number that would allow the size of one earthquake to be compared with another.

Which of the following scales are not linear in nature ?
(i) Decibel
(ii) Richter
(iii) Meter

  1. (i) only

  2. (ii) and (iii)

  3. (ii) only

  4. (i) and (ii)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The answer is D.

The decibel (dB) is a logarithmic unit used to express the ratio between two values of a physical quantity, often power or intensity. One of these quantities is often a reference value, and in this case, the decibel can be used to express the absolute level of the physical quantity, as in the case of sound pressure. The number of decibels is ten times the logarithm to base 10 of the ratio of two power quantities, or of the ratio of the squares of two field amplitude quantities.
The Richter scale is not a linear scale. This means that an earthquake of magnitude 6 does not have twice as destructive power as the earthquake of magnitude 3. Actually, an earthquake with magnitude 5 is ten times more destructive than an earthquake of magnitude 4. The Richter scale is a logarithmic scale.
The Meter scale is a linear scale.
Hence, (i) and (ii) are non-linear scales.

Which instrument record the direction of movement of earthquake waves?

  1. Richter scale

  2. Seismograph

  3. Mercalli scale

  4. All of the above

B Correct answer
Explanation

A seismograph or seismometer is an instrument which is used to record the direction of movement of earthquake waves. The first seismograph was invented in 132 A.D. by the Chinese astronomer and mathematician Chang Heng.

Which of the following is/are the measuring instrument of earthquake?

  1. Seismograph

  2. Richter Scale

  3. Mercalli Scale

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

All three following instruments are useful in measuring the seismic activity under the earth's surface. A seismometer is an instrument that responds to ground motions, such as caused by earthquakes, volcanic eruptions. Richter scale a quantitative measure of an earthquake's magnitude. The modified Mercalli intensity scale also measures the effect of an earthquake on the Earth's surface.

The Mercalli scale grades the earthquake on _____________.

  1. 10-point scale

  2. 12-point scale

  3. 15-point scale

  4. 20-point scale
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The modified Mercalli intensity scale also measures the effect of an earthquake on the Earth's surface. The Mercalli scale grades the earthquake on a 12-point scale. The intensity scale helps to analyze the data by constructing isoseismal curves, which are lines that connect points of equal intensity.
