Questions Related to earthquakes and volcanoes

The fragmented outermost layers of earth are known as _____.

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. Crusts

  2. Plates

  3. Cores

  4. Zones

Show answer
Correct Option: B
Explanation:

Currently, geologists are working on the theory of plate tectonics. Geologically speaking, a "plate" is a large, rigid slab of rock. The theory of plate tectonics states that the earth's outermost, rigid layer, the lithosphere, is fragmented into a dozen or more irregularly shaped plates that are riding atop a hotter, more mobile material, the asthenosphere.

Wettest place on Earth is _____________.

  1. Nongpoh

  2. Cherrapunji

  3. Jowai

  4. Baghmara

Show answer
Correct Option: B
Explanation:

Sohra (temporarily called Cherrapunjee or Cherrapunji) is a subdivisional town in the East Khasi Hills district in the Indian state of Meghalaya. Sohra has often been credited as being the wettest place on Earth, but for now nearby Mawsynram currently holds that distinction.

 

Tectonic plate boundaries may be _________.

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. Convergent

  2. Divergent

  3. Both $(1)$ and $(2)$

  4. None ofthese

Show answer
Correct Option: C
Explanation:

There are three kinds of plate tectonic boundaries: divergent, convergent, and transform plate boundaries. A divergent boundary occurs when two tectonic plates move away from each other. When two plates come together, it is known as a convergent boundary. 

Which of the following movement give rise to continents?

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. Orogenic movement

  2. Epiorogenic movement

  3. Rapid movement

  4. Mass movement

Show answer
Correct Option: B
Explanation:

 The word Epeirogenetic consists of two words viz, 'epiros' means continent and 'genesis' means origin. So eperiogenetic movement gives rise to the continent. Epeirogenetic movement causes upliftment  and subsidence of continental masses through upward and downward movements respectively. Both, the movements are vertical movement. 

The movements in the interior of the earth caused by continuous and slow emission of energy are called _____________.

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. slow movement

  2. weathering

  3. rapid movement

  4. mass movement

Show answer
Correct Option: A
Explanation:

The Powerful internal forces operating from within the crust are called Earth Movements which bring about vast changes on the earth's surface are called Earth Movements. They may be slow and sudden. Slow movements occurs at a very slow rate and continue much longer as compared to our life span. These movements are relative to each other, the land advancing against sea is termed as negative movement and the sea advancing on land is known as positive movement.


Mountains and continents are formed due to ___________.

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. rapid earth movement

  2. slow earth movement

  3. weathering

  4. erosion

Show answer
Correct Option: B
Explanation:

Mountain and continents are formed due to slow earth movement. Slow forces include both vertical and horizontal movements which are caused due to forces deep within the earth. These forces operate very slowly and their effects become discernible after thousands and million of year. 

The surface relief of the earth is moulded by which of the following forces?

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. Tectonic

  2. Gradational

  3. Both a and b

  4. None of the above

Show answer
Correct Option: C

When the tectonic plates move away from each other it is called _____________.

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. convergent plate

  2. drifting plate

  3. static plates

  4. none of the above

Show answer
Correct Option: B
Explanation:
The movement of the plates results in the building up of stresses within the plates and the continental rocks above, leading to folding, faulting, and volcanic activity. When the tectonic plates move away from each other it is called a drifting plate.

How many major tectonic plates are there on earth?

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. 5

  2. 7

  3. 8

  4. 10

Show answer
Correct Option: B
Explanation:

There are seven main or “primary” tectonic plates: these are the African Plate: Antarctic Plate, Eurasian Plate, Indo-Australian Plate, North American Plate, Pacific Plate, and South American Plate.

From which sea the Himalayan mountain was emerged?

geography earthquakes and volcanoes volcanism types and features of earthquakes and volcanoes movement of the earth's plates

  1. Dead sea

  2. Mediterranean sea

  3. Tethys sea

  4. Caspian sea

Show answer
Correct Option: C
Explanation:
The Himalayan uplift out of the Tethys sea and subsidence of the northern flank of the peninsular plateau resulted in the formation of a large basin.
