Which statements describe the Richter scale?

Which statements describe the Richter scale?

It measures large earthquakes far from the seismograph. It estimates the total energy released from an earthquake. It increases in magnitude as amount of damage increases. It determines an earthquake’s magnitude based on the size of its seismic waves.

What are the 3 earthquake scales?

Because of the limitations of all three magnitude scales (ML, Mb, and Ms), a new, more uniformly applicable extension of the magnitude scale, known as moment magnitude, or Mw, was developed. In particular, for very large earthquakes, moment magnitude gives the most reliable estimate of earthquake size.

What are the 3 earthquake scales and what do they measure?

The Richter scale is most common in the United States, while worldwide, scientists rely on the Mercalli scale. The moment magnitude scale is another earthquake measurement scale used by some seismologists. All three scales provide useful information in measuring and analyzing earthquakes across the globe.

Which factors are involved in earthquake formation?

Explanation: Breaking rocks is one the factors that is involved during the formation of an earthquake. As rock breaks, there is a sudden release of energy into the surrounding.

Which statement best explains why Earth’s outer core is in liquid form?

Which statement best explains why Earth’s outer core is in liquid form? The iron-nickel alloy melts due to hot temperatures.

Which of the following is measured by modified Mercalli scale?

The modified Mercalli intensity scale (MM or MMI), developed from Giuseppe Mercalli’s Mercalli intensity scale of 1902, is a seismic intensity scale used for measuring the intensity of shaking produced by an earthquake.

What statement describes seismic waves?

A seismic wave is an elastic wave generated by an impulse such as an earthquake or an explosion. Seismic waves may travel either along or near the earth’s surface (Rayleigh and Love waves) or through the earth’s interior (P and S waves).

What is difference between compression and rarefaction?

Compression- a region in a longitudinal (sound) wave where the particles are closest together. Rarefaction- a region in a longitudinal (sound) wave where the particles are furthest apart.

Which statements describe the Richter scale?

It measures large earthquakes far from the seismograph. It estimates the total energy released from an earthquake. It increases in magnitude as amount of damage increases. It determines an earthquake’s magnitude based on the size of its seismic waves.

Does the Richter scale gauge fault movement?

Richter substituted measurements of the amount of ground vibration, as measured by a seismograph, for measurements of luminosity. Seismic magnitude is not a measure of the physical size of the earthquake fault (as might be quantified by its area or its slip) but rather of the amount of vibration that it emits.

How does the Richter scale work What does it measure?

The Richter scale measures the maximum amplitude of seismic waves as they reach seismographs. This scale is expressed with a logarithmic scale. Thus, an earthquake measuring 7.0 on the Richter scale would be 10 times larger than an earthquake that measures 6.0.

Which statements describe surface waves Check all that apply they arrive before S waves they travel slower than P waves they result in much ground motion they are produced by P and S waves they travel deep below?

These travel slower than S waves and P waves but have large amplitudes which could much ground motion and cause huge destruction. Hence, the statements describe the surface waves: They travel slower than P waves.

What are the two primary types of waves generated by earthquakes?

NARRATOR: Earthquakes generate two main types of seismic, or shock, waves: body waves and surface waves. Body waves travel through the interior of the earth. The fastest of these are primary, or “P,” waves.

What is a shadow zone and why does it exist quizlet?

Shadow zones are spots on Earth’s surface where one type of seismic wave does not reach. They exist because P-waves and S-waves bend as they travel through different materials. The bending prevents the waves from reaching some parts of Earth.

Which type of waves are compressional in nature?

P waves, also called compressional or longitudinal waves, give the transmitting medium—whether liquid, solid, or gas—a back-and-forth motion in the direction of the path of propagation, thus stretching or compressing the medium as the wave passes any one point in a manner similar to that of sound waves in air.
