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

The movement of tectonic plates is due to thermal energy from  _______.

  1. Mantle

  2. Crust

  3. Inner Core

  4. Outer Core
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The movement of tectonic plates is due to the enormous amount of thermal energy generated in the inner core and transferred to the mantle thus, causing movement in the tectonic plates.

Option $C$ is correct.

Collisions of plates produce mountain ranges and other irregular surface features in ________.

  1. Land

  2. Ocean floor

  3. Both A & B

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

Plate collisions occur at convergent boundaries, which can happen on continental landmasses (forming mountain ranges like the Himalayas) or on the ocean floor (forming deep-sea trenches and island arcs).

In the transform boundary, the plates ________. 

  1. slide horizontally past each other

  2. pull away from each other

  3. moves toward each other

  4. sinks under another
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

At a transform plate boundary, tectonic plates slide horizontally past one another. Crust is neither created nor destroyed at these boundaries.

What is the location where sinking of plate occurs called?

  1. Sinking Zone

  2. Subduction Zone

  3. Sliding Zone

  4. Boundary Zone
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A subduction zone is a geological process that takes place at convergent boundaries of tectonic plates where one plate moves under another and is forced to sink due to high gravitational potential energy into the mantle.

Approximately 140 million years ago, Indian plate broke away from the ancient
supercontinent known as  _______.

  1. Pangaea

  2. Gondwanaland

  3. Both A & B

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

The Indian Plate was part of the supercontinent Gondwanaland. It began to break away and drift northward approximately 140 million years ago.

The Gondwanaland, comprised of modern Africa and _________.

  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.
