Questions and Answers
- 1.
What is the name given to the strength of an earthquake that can be felt at the surface?
- A.
Richter scale
- B.
Seismograph
- C.
Intensity
- D.
Triangulation
Correct Answer
C. IntensityExplanation
Intensity is the name given to the strength of an earthquake that can be felt at the surface. It measures the effects of an earthquake on people, buildings, and the environment. The Richter scale, on the other hand, measures the magnitude or energy release of an earthquake. A seismograph is a device used to record seismic waves, and triangulation is a method used to locate the epicenter of an earthquake.Rate this question:

A scale that measures the energy released by an earthquake based on seismic wave size is called ___________
- A.
Triangulation
- B.
Intensity
- C.
Seismograph
- D.
Richter scale
Correct Answer
D. Richter scaleExplanation
The Richter scale is a scale that measures the energy released by an earthquake based on the size of seismic waves. It was developed by Charles F. Richter in 1935 and is widely used to quantify the magnitude of earthquakes. The scale is logarithmic, meaning that each whole number increase on the scale represents a tenfold increase in the amplitude of the seismic waves and approximately 31.6 times more energy released. The Richter scale provides a standardized way to compare the relative strength of earthquakes and is an essential tool in seismology.Rate this question:

An instrument that measures the energy of earthquake vibrations at a given location.
- A.
Triangulation
- B.
Intensity
- C.
Seismograph
- D.
Richter scale
Correct Answer
C. SeismographExplanation
A seismograph is an instrument used to measure the energy of earthquake vibrations at a specific location. It consists of a pendulum or a mass on a spring that is sensitive to ground motion. When an earthquake occurs, the ground shakes and the seismograph records the movement, producing a seismogram. This instrument is essential in monitoring and studying earthquakes, as it provides valuable data such as the magnitude, duration, and frequency of the seismic waves. It helps scientists understand the characteristics and behavior of earthquakes, which is crucial for assessing their potential impact and developing effective measures for earthquake preparedness and response.Rate this question:

Using information from at least three seismograph stations to find the location of the epicenter of an earthquake is referred to as ___________________
- A.
Triangulation
- B.
Intensity
- C.
Seismograph
- D.
Richter scale
Correct Answer
A. TriangulationExplanation
Triangulation is the process of using information from multiple seismograph stations to determine the exact location of an earthquake's epicenter. By measuring the arrival times of seismic waves at different stations, scientists can calculate the distance between each station and the epicenter. By drawing circles with these distances as radii, the point where the circles intersect represents the epicenter. Triangulation is a reliable method for pinpointing earthquake locations and is widely used in seismology.Rate this question:

What name is given to the point below the surface of Earth where an earthquake begins?
- A.
Mercalli scale
- B.
Seismograph
- C.
Focus
- D.
Seismically safe
Correct Answer
C. FocusExplanation
The correct answer is "Focus". The focus is the point below the surface of the Earth where an earthquake begins. It is the location where the seismic energy is released and the rocks break, causing the ground to shake. The focus can be at varying depths within the Earth's crust, and its location is crucial in determining the intensity and effects of an earthquake.Rate this question:

In the list of words below, identify how buildings that are built to resist the largest earthquake that can happen in an area are described.
- A.
Seismograph
- B.
Fault zones
- C.
Mercalli scale
- D.
Seismically safe
Correct Answer
D. Seismically safeExplanation
The term "seismically safe" refers to buildings that are constructed in a way that enables them to withstand the largest possible earthquake that can occur in a particular area. These buildings are designed with special features and materials that can absorb and dissipate seismic forces, reducing the risk of structural damage and collapse during an earthquake. The term "seismically safe" implies that the building has been engineered to meet specific seismic design criteria and standards, ensuring the safety of its occupants during a seismic event.Rate this question:

Which one of the following measures should you take before an earthquake?
- A.
Check yourself for injuries.
- B.
Get under your desk, and follow the school emergency plan.
- C.
Make an emergency escape plan.
- D.
Do nothing.
Correct Answer
C. Make an emergency escape plan.Explanation
Before an earthquake, it is important to make an emergency escape plan. This is because during an earthquake, there may be a need to quickly evacuate the area to ensure personal safety. Having an escape plan in place helps individuals and families to be prepared and know what steps to take in case of an earthquake, such as identifying safe exit routes, meeting points, and necessary supplies to take with them. This measure can greatly increase the chances of a safe evacuation and minimize potential harm or injuries.Rate this question:

- B.
Get under your desk, and follow the school emergency plan.
- C.
Make an emergency escape plan.
- D.
Do nothing.
Correct Answer
B. Get under your desk, and follow the school emergency plan.Explanation
During an earthquake, it is important to take measures to ensure personal safety. Getting under a desk provides protection from falling objects and reduces the risk of injury. Following the school emergency plan is crucial as it outlines the necessary steps to be taken in case of an earthquake, ensuring a coordinated and organized response. Checking oneself for injuries is also important to address any immediate medical needs. Making an emergency escape plan is generally recommended, but it is not the immediate action to be taken during an earthquake. Doing nothing is not a suitable response as it puts one at risk of harm.Rate this question:

Which one of the following measures should you take after an earthquake?
- A.
Check yourself for injuries.
- B.
Get under your desk, and follow the school emergency plan.
- C.
Make an emergency escape plan.
- D.
Do nothing.
Correct Answer
A. Check yourself for injuries.Explanation
After an earthquake, it is important to prioritize personal safety. Checking oneself for injuries is crucial as earthquakes can cause physical harm. By assessing our own condition, we can determine if we need immediate medical attention and seek help accordingly. This step ensures that we address any potential injuries and take appropriate actions to ensure our well-being.Rate this question:

In what types of places are earthquakes are common?
- A.
Richter scale
- B.
Fault zones
- C.
Seismically safe
- D.
Estuaries
Correct Answer
B. Fault zonesExplanation
Earthquakes are common in fault zones. Fault zones are areas where there is a fracture or break in the Earth's crust, resulting in the movement of tectonic plates. These movements can cause earthquakes as the plates rub against each other, creating seismic activity. Fault zones are therefore the most likely places for earthquakes to occur. The Richter scale is a measurement used to quantify the magnitude of an earthquake, while seismically safe refers to structures or buildings designed to withstand earthquakes. Estuaries, on the other hand, are coastal areas where rivers meet the sea and are not directly related to earthquake activity.Rate this question:
