Question

An earthquake is a shaking of the ground that occurs as Earth’s plates interact due volcanic eruptions or forces underneath Earth’s surface. Earthquakes that occur where plates rub against each other are not deep but are very powerful. At areas where plates collide, earthquakes are deep and powerful. When two plates pull away from each other, earthquakes that are not deep and not powerful may occur. Which statement best summarizes the information in the paragraph? Earthquakes may occur at all types of plate boundaries. The strength of an earthquake depends on the type of boundary. All earthquakes at plate boundaries result from forces underneath Earth’s surface or volcanic eruptions. Different types of plate interactions result in earthquakes of varying strengths at various depths.

Answer 1

Answer:

An earthquake is caused by a sudden slip on a fault. ... When the stress on the edge overcomes the friction, there is an earthquake that releases energy in waves that travel through the earth's crust and cause the shaking that we feel

Answer:

Explanation:

Earthquake:

• An earthquake is a quick shaking or trembling of the earth's surface brought on by seismic waves or earthquake waves that are produced as a result of an abrupt movement (an abrupt release of energy) in the earth's crust (earthquakes with shallow foci) or upper mantle (some shallow-focus and all intermediate and deep-focus earthquakes).
• A seismograph, sometimes known as a seismometer, is a device used to identify and document earthquakes.

Focus and epicenter:

• The focus or hypocenter of an earthquake is the location where the energy is released.
• Epicenter refers to the location on the surface that is directly above the focus (first surface point to experience the earthquake waves).
• An isoseismic line is defined as a line that connects all places on a surface when the intensity is the same.

Foreshocks and aftershocks:

• Typically, many smaller earthquakes known as aftershocks occur after a strong or even moderate earthquake with a shallow center.
• A foreshock is a small earthquake that occurs before an earthquake's more intense shaking motion.

Swarms:

• A location may experience numerous little earthquakes for months without experiencing a large quake.
• Earthquake swarms are a type of such sequence of earthquakes.
• Swarms of earthquakes frequently accompany volcanic activity.
• Swarms of earthquakes can be used to pinpoint where the moving magma is within a volcano.

Faulty zones:

• The abrupt release of tension along a fault rupture (crack) in the earth's crust is the primary source of the majority of shallow earthquakes.
• Due to the extreme pressure and temperature inside the earth, rock volume and density are constantly changing, causing sudden slippage of rock formations along fault ruptures in the crust of the planet.
• Deformity and Fracture Stephen Earle
• The resulting magnitude increases as the length and width of the faulted area increase.
• The longest earthquake ruptures (convergent boundary) along thrust faults are roughly 1,000 km long.
• On strike-slip faults (transform fault), the longest earthquake ruptures are between 50 and 30 percent shorter than those along thrust faults.
• Normal faults' (divergent boundary) fault ruptures are shorter.

Plate tectonics:

• Earthquakes are caused by the slipping of land along a fault line along convergent, divergent, and transform boundaries.
• Megathrust earthquakes, which are the most powerful earthquakes and account for nearly all earthquakes with a magnitude of 8 or above, are related with reverse faults (convergent boundary).
• At subduction zones, when one tectonic plate is pushed beneath another, megathrust earthquakes take place. as in the Indian Ocean earthquake of 2004.
• Major earthquakes up to around magnitude 8 can be caused by strike-slip faults, especially continental transformations.
• The San Andreas Fault is a transform fault where earthquakes occur along the fault lines when the Pacific Plate and North American Plate move horizontally in relation to one another.
