  1. Volcanic eruptions

  2. Landslides

  3. Tsunamis

  4. Movement of tectonic plates
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The most common cause of earthquakes is the movement of tectonic plates, which can cause sudden releases of energy.

Multiple choice

What is the name of the tectonic plate that India is located on?

  1. Eurasian Plate

  2. Indian Plate

  3. African Plate

  4. North American Plate
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Indian Plate is a tectonic plate that lies beneath the Indian subcontinent and the surrounding regions. It is bounded by the Eurasian Plate to the north, the African Plate to the west, and the Australian Plate to the east.

Multiple choice

What is the process by which tectonic plates move?

  1. Convection

  2. Radiation

  3. Conduction

  4. Subduction
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Convection is the process by which heat is transferred through the movement of fluids. In the case of tectonic plates, convection occurs in the Earth's mantle, where hot rock rises and cooler rock sinks. This movement causes the plates to move.

Multiple choice

What is the name of the boundary between two tectonic plates that are moving apart?

  1. Convergent boundary

  2. Divergent boundary

  3. Transform boundary

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

A divergent boundary is a boundary between two tectonic plates that are moving apart. At a divergent boundary, new oceanic crust is formed as magma rises from the Earth's mantle and fills the gap between the plates.

Multiple choice

What is the name of the boundary between two tectonic plates that are moving towards each other?

  1. Convergent boundary

  2. Divergent boundary

  3. Transform boundary

  4. Subduction zone
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A convergent boundary is a boundary between two tectonic plates that are moving towards each other. At a convergent boundary, one plate may be subducted beneath the other, or the two plates may collide and form mountains.

Multiple choice

What is the name of the boundary between two tectonic plates that are sliding past each other?

  1. Convergent boundary

  2. Divergent boundary

  3. Transform boundary

  4. Subduction zone
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A transform boundary is a boundary between two tectonic plates that are sliding past each other. At a transform boundary, the plates are moving in opposite directions, but they are not moving towards or away from each other.
