Questions Related to earthquake

The strength of an earthquake is rated on a scale called Richter scale.

geography lithosphere and landforms earthquake earthquakes earth's movement and creation of landforms

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. The magnitude of an earthquake is determined from the logarithm of the amplitude of waves recorded by seismographs. Adjustments are included for the variation in the distance between the various seismographs and the epicenter of the earthquakes. On the Richter scale, magnitude is expressed in whole numbers and decimal fractions.

The probabilistic assessment of general earthquake hazards is called as __________.

geography lithosphere and landforms earthquake earthquakes earth's movement and creation of landforms

  1. Earthquake forecasting

  2. Earthquake prediction

  3. Both a and b

  4. None of these

Show answer
Correct Option: A

Earthquake prediction is a branch of __________.

geography lithosphere and landforms earthquake earthquakes earth's movement and creation of landforms

  1. Seismology

  2. Microbiology

  3. Bacteriology

  4. None of these

Show answer
Correct Option: A
Explanation:
  • Seismology is the study of earthquakes which involves the prediction of earthquakes, hence option A is correct.
  • Microbiology is the study of microorganisms and bacteriology is the study of bacteria, thus both are incorrect.

The instrument used to measure earthquake wave is called _________.

geography lithosphere and landforms earthquake earthquakes earth's movement and creation of landforms

  1. Seismograph

  2. Richter scale

  3. Barometer

  4. None of the above

Show answer
Correct Option: A
Explanation:

The tremors produce wave on the surface of the earth. These are called seismic waves. The waves are recorded by an instrument called the seismograph.

An Earthquake on the sea floor or close to the coast may cause __________.

geography natural disasters - public awareness for disaster risk reduction earthquake earthquakes earth's movement and creation of landforms

  1. landslide

  2. tsunami

  3. flood

  4. none of these

Show answer
Correct Option: B
Explanation:
  • Tsunamis are the catastrophic harbour waves caused by the displacement of a large amount of water at the seafloor.
  • This displacement is often triggered by an earthquake at the seafloor thus option B is correct.
  • Landslides are unrelated hence incorrect while Tsunamis may lead to flooding at the coastal zones. However, to chose one option the tsunami is the most direct answer to this question.

An ____ is the release of a liquid petroleum hydrocarbon into the environment.

  1. Ozone Spill

  2. Oil Spill

  3. Nitrogen Spill

  4. Uranium Spill

Correct Option: B

State whether these sentences are true (T) or false (F).
Mt. Fujiyama in Japan is an example of volcanic mountains. 

geography endogenetic movements endogenic process and creation of mountains major domains of the earth land and oceans study of continents - north america earth's movement and creation of landforms earthquake earthquakes

  1. True

  2. False

Show answer
Correct Option: A
Explanation:

True,

Mount Fuji, Japan. The 3,776-meter-high (12,388 feet) Mount Fuji Volcano, located on the island of Honshu in Japan, is one of the world's classic examples of a stratovolcano. No further eruptions have occurred at Mount Fuji, but steam was observed at the summit from 1780–1820, and the volcano is considered active.

Which of the following rivers occupies a riftvalley?

  1. Narmada

  2. Cauvery

  3. Mahanadi

  4. Sutlej

Show answer
Correct Option: A
Explanation:

Narmada river rises in the Amarkantaka hills in Madhya Pradesh. It flows towards the west in a rift valley formed due to faulting. Its length is about 1312 km. This river drains into the Arabian Sea. It flows through the states of Madhya Pradesh, Maharashtra, and Gujarat.

Which of the following regions is the best example of Rift Valley?

  1. Peninsular India

  2. East Africa

  3. Dead-Sea basin

  4. Scotland

Show answer
Correct Option: B
Explanation:
  • A Rift valley is a narrow linear depression in the land surrounded by mountain ranges. It is created by a geological fault in earth's crust. The East African Rift valley which runs thousands of km long is the best example of a Rift valley in the world.

Rift valley means _______________________.

geography endogenetic movements endogenic process and creation of mountains major domains of the earth land and oceans study of continents - north america earth's movement and creation of landforms earthquake earthquakes

  1. A steep valley by river erosion

  2. A valley with gentle slopes

  3. A valley formed by the sinking of ground between two almost parallel faults

  4. A valley carved by aeolian erosion

Show answer
Correct Option: C
Explanation:
  • When two plates of earth's crust move apart from each other, a long narrow depression is formed due to the sinking of ground which is called a rift valley eg. east African rift valley. Hence option C is the right answer.
  • The rift valley is not formed due to river or aeolian(wind) action. Also, the slope in the rift valley is almost vertical thus very steep hence other options are incorrect.
