Coastal erosion is more severe along the coast of the state ______.

geography indian natural disasters disasters - case studies major hazards in india and prevention tsunami and floods man made disaster

  1. Kerala

  2. Tamil Nadu

  3. Orissa

  4. West Bengal.

Show answer
Correct Option: A
Explanation:

Coastal erosion is confined to southwest monsoon season when the waves are rough. Seawalls and groynes are the major management strategies adopted for coastal protection along Kerala coast. As per Shoreline Change Assessment data, about 63 percent of the coastline of Kerala is eroding.

The intensity of earthquake is measured on the _________.

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

  1. richter scale

  2. kelvin scale

  3. mercury scale

  4. all of the above

Show answer
Correct Option: A
Explanation:

Answer is A.

The intensity of earthquake is measure on the richter scale.
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 in the magnitude formula to compensate 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. For example, a magnitude of 5.3 might be computed for a moderate earthquake, and a strong earthquake might be rated as magnitude 6.3. Because of the logarithmic basis of the scale, each whole number increase in magnitude represents a tenfold increase in measured amplitude; as an estimate of energy, each whole number step in the magnitude scale corresponds to the release of about 31 times more energy than the amount associated with the preceding whole number value.

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

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

Show answer
Correct Option: B

Choose the correct option to complete the statements given below: 
The heat zone with the coldest climate is the _______

geography natural regions of the world tropical desert regions natural regions weather maps

  1. Torrid Zone

  2. Northern Temperate Zone

  3. The Frigid Zones

  4. either of the Temperate Zones

Show answer
Correct Option: C
Explanation:

There three heat zone on the earth.

The heat zone with coldest climate is known as a Frigid zone. It is a permanently frozen zone.

Eskimos live by _____.

geography natural regions of the world tropical desert regions natural regions weather maps

  1. Hunting

  2. Fishing

  3. Both A & B

  4. None of these

Show answer
Correct Option: C
Explanation:

Hunting and fishing is the main occupation of Eskimos. They hunt caribou, musk ox and other animals. Hunters do not apply the same techniques they use in many parts of the world due to lack of trees. Over hunting seriously endangers some species in the far north, especially musk oxen. Some natives are dependent on fishing as their occupation.
