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

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

  3. Both a and b

  4. None of these

A Correct answer
Explanation

Earthquake forecasting refers to the probabilistic assessment of hazards, whereas prediction implies specifying a precise time, location, and magnitude, which is currently not scientifically possible.

Earthquake prediction is a branch of __________.

  1. Seismology

  2. Microbiology

  3. Bacteriology

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

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

  1. landslide

  2. tsunami

  3. flood

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
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.

  3. Mahanadi

  4. Sutlej
Reveal answer Fill a bubble to check yourself
A Correct answer
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
Reveal answer Fill a bubble to check yourself
B Correct answer
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 _______________________.

  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
Reveal answer Fill a bubble to check yourself
C Correct answer
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.
