Question 1:

Which tectonic boundary is primarily associated with the occurrence of earthquakes?

Explanation: Earthquakes primarily occur at tectonic boundaries where there is significant movement and interaction between tectonic plates. The most common boundary associated with earthquakes is the transform boundary, where two plates slide past each other. Therefore, the correct answer is C) Transform boundary.

Question 2:

Which tectonic feature is formed when rocks fracture and move along a fault plane?

Explanation: When rocks fracture and move along a fault plane, it results in the occurrence of an earthquake. An earthquake is the shaking of the Earth's surface caused by the release of energy in the Earth's crust. Therefore, the correct answer is D) Earthquake.

Question 3:

Which scale is commonly used to measure the magnitude of earthquakes?

Explanation: The Richter scale is commonly used to measure the magnitude of earthquakes. It quantifies the amount of energy released during an earthquake by measuring the amplitude of seismic waves. Therefore, the correct answer is A) Richter scale.

Question 4:

Which type of earthquake occurs at a convergent boundary where one tectonic plate is forced beneath another?

Explanation: A reverse earthquake occurs at a convergent boundary where one tectonic plate is forced beneath another in a process called subduction. The overriding plate is thrust upward, resulting in a reverse fault and the occurrence of a reverse earthquake. Therefore, the correct answer is C) Reverse earthquake.

Question 5:

Which region of the Earth is most seismically active?

Explanation: The region of the Earth that is most seismically active is the plate boundaries. This is because earthquakes primarily occur at tectonic boundaries where there is significant movement and interaction between tectonic plates. Therefore, the correct answer is D) Plate boundaries.
