  1. Australia

  2. Antarctica

  3. South America

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gondwanaland was a supercontinent that included modern Africa, South America, Antarctica, Australia, and the Indian subcontinent. Since all listed options are parts of the former Gondwanaland, 'All of these' is the correct choice.

Continental Plates are _________.

  1. thinner than Oceanic Plates

  2. thicker than Oceanic Plates

  3. equal in thickness to Oceanic Plates

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Continental plates are composed primarily of granitic rocks, which are less dense and thicker than the basaltic rocks that make up oceanic plates. Because they are less dense, they 'float' higher on the mantle, resulting in greater thickness.

The great rift valley of East Africa is a notable example for the process of ________.

  1. folding

  2. faulting

  3. volcanic activity

  4. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Great Rift Valley is formed by the divergence of tectonic plates, which causes the crust to crack and drop down between parallel faults. This process is known as faulting.

The fragmented outermost layers of earth are known as _____.

  1. Crusts

  2. Plates

  3. Cores

  4. Zones
Reveal answer Fill a bubble to check yourself
B Correct answer
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

B Correct answer
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 _________.

  1. Convergent

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

  4. None ofthese
Reveal answer Fill a bubble to check yourself
C Correct answer
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?

  1. Orogenic movement

  2. Epiorogenic movement

  3. Rapid movement

  4. Mass movement
Reveal answer Fill a bubble to check yourself
B Correct answer
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.
