3. Which type of earthquake is caused by a sudden movement of rocks or the movement of tectonic plates?
A. Tectonic earthquake
B. Volcanic earthquake
C. Artificial earthquake
D. Man-made earthquake

Answer :

Final answer:

The point of origin of an earthquake is called the 'focus.' Earthquakes themselves are caused by sudden movements in the Earth's crust. Tectonic earthquakes occur as a result of rock movement along tectonic plates.


Explanation:

Understanding Earthquakes


To answer the questions posed, let's break down each one systematically:



  1. What is the point of origin of an earthquake below the surface of the earth?
    The correct answer is B. focus. The focus is the precise point within the earth where the earthquake originates, and the seismic waves radiate outward from this point.

  2. Which phenomenon is caused by a sudden movement or vibration of the earth's crust that causes changes on its surface?
    The correct answer is C. earthquake. An earthquake results from the sudden release of energy caused by the movement of tectonic plates, generating seismic waves that can cause ground shaking.

  3. Which type of earthquake is caused by a sudden movement of rocks or the movement of tectonic plates?
    The correct answer is A. tectonic earthquake. Tectonic earthquakes occur due to the movements of the earth's plates, leading to stress accumulation and subsequent sudden release.


These concepts are fundamental in geology, as they help us understand the dynamic processes of our planet.
