What is a characteristic of S waves?
They shake particles at right angles to the direction that they travel.
They travel faster than P waves.
They can travel through liquids and solids.
They are not seismic waves.
What does the Elastic Rebound Hypothesis explain?
The process by which rocks deform and then return to their original shape after an earthquake
The way rocks are formed from magma
The process of weathering and erosion
The movement of tectonic plates without any energy release
Which type of seismic wave causes material to shake at right angles to the direction of wave motion?
P waves
S waves
Surface waves
Love waves
What happens when the strength of a rock is exceeded, according to the Elastic Rebound Hypothesis?
The rock suddenly breaks, causing the vibrations of an earthquake
The rock melts and forms magma
The rock slowly bends without breaking
The rock turns into soil
What is the Richter Scale based on?
The amplitude of the largest seismic wave
The duration of the earthquake
The depth of the earthquake's focus
The number of aftershocks
What are the two different types of measurements historically used by scientists to describe the size of an earthquake?
Intensity and magnitude
Speed and direction
Depth and duration
Temperature and pressure
Which of the following statements best describes P waves?
They are push-pull waves that compress and expand in the direction the waves travel.
They are waves that only travel through liquids.
They are waves that move in a circular motion.
They are waves that have the slowest velocity.
What is the main cause of most earthquakes according to the Elastic Rebound Hypothesis?
The rapid release of elastic energy stored in rock subjected to great forces
The slow movement of tectonic plates without any energy release
The cooling and solidification of magma beneath the Earth's surface
The accumulation of water in underground reservoirs
Which instrument is used to detect and record seismic waves generated by earthquakes?
Anemometer
Seismograph
Barometer
Thermometer
Through which materials can P waves travel?
Solids, liquids, and gases
Only solids
Only liquids and gases

What type of seismic wave alternately compresses and expands the material through which it passes?
P waves
S waves
Surface waves
Rayleigh waves
What is an aftershock?
A small earthquake that follows the main earthquake.
A large earthquake that occurs after a foreshock.
A small earthquake that precedes a major earthquake.
A type of volcanic eruption.
What is ground subsidence as mentioned in the context of earthquake dangers?
The sinking of the ground triggered by vibrations
The rising of the ground due to pressure
The cracking of the ground from heat
The flooding of the ground from rain
What is the focus of an earthquake?
The point within Earth where the earthquake starts
The location on the surface directly above the earthquake
The area where the most damage occurs
The boundary between two tectonic plates
What are faults in the context of earthquakes?
Fractures in Earth where movement has occurred
Large mountains formed by tectonic activity
Areas of high volcanic activity
Deep ocean trenches
