geography our changing earth earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. Earth movements

  2. Earth motion

  3. Earthquake

  4. Earth dissolution

Show answer
Correct Option: C

Sudden shaking of a part of the earth is called ______.

geography our changing earth earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. tsunami

  2. volcanic eruption

  3. hurricane

  4. earthquake

Show answer
Correct Option: D
Explanation:

An earthquake is the sudden shaking of the surface of the Earth, resulting from the sudden release of energy in the Earth's lithosphere that creates seismic waves. Earthquakes can be violent enough to toss people around and destroy whole cities. The seismicity or seismic activity of an area refers to the frequency, type and size of earthquakes experienced over a period of time.

Richter scale is a/an ______ aide to measure earth tremors.

  1. Exponential

  2. Logarithmic

  3. Geometric

  4. Physical

Correct Option: B

Waves produced due to the earthquake are known as ___________.

geography endogenetic movements earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. seismic waves

  2. shock waves

  3. infrasonic waves

  4. none of these

Show answer
Correct Option: A
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.

Which of the following is not in the seismic zone of India?

  1. Jaisalmer

  2. Kangra

  3. Dehra Dun

  4. North Bihar

  1. a-(iv), b-(ii), c-(i), d-(iii)

  2. a-(iii), b-(i), c-(ii), d-(iv)

  3. a-(i), b-(iii), c-(iv), d-(ii)

  4. a-(ii), b-(iv), c-(i), d-(iii)

Show answer
Correct Option: B
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 _______.

geography endogenetic movements earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  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

Show answer
Correct Option: A

The magnitude of the earthquake is measured on the ______________.

geography endogenetic movements earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. Wind vane

  2. Barometre

  3. Richter scale

  4. Weighing scale

Show answer
Correct Option: C
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

geography endogenetic movements earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. (i) only

  2. (ii) and (iii)

  3. (ii) only

  4. (i) and (ii)

Show answer
Correct Option: D
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?

geography endogenetic movements earthquake earthquakes earth's movement and creation of landforms endogenic process and creation of mountains

  1. Richter scale

  2. Seismograph

  3. Mercalli scale

  4. All of the above

Show answer
Correct Option: B
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.
