What is the scale that measures the magnitude of an earthquake?
The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.
Which statements describe the focus of an earthquake check all that apply?
The statements that describe the focus of an earthquake are the following: it develops in the lithosphere, it is the starting point of an earthquake, it begins about 100 kilometers below earth’s surface. Many spots on earth are prone to earthquakes and major risks for people living in these regions.
Which factor does the moment magnitude scale estimate quizlet?
– This scale measures the magnitude of an earthquake based on the size of seismic waves. This scale rates an earthquake according to how much damage it causes.
Which factors does the moment magnitude scale estimate?
Moment magnitude measures the size of events in terms of how much energy is released. Specifically, moment magnitude relates to the amount of movement by rock (i.e. the distance of movement along a fault or fracture) and the area of the fault or fracture surface.
How are S waves and surface waves similar?
Unlike P waves, S waves can travel only through solid materials. After both P and S waves have moved through the body of Earth, they are followed by surface waves, which travel along Earth’s surface. Surface waves travel only through solid media. This motion is similar to that observed in ocean waves.
Which strategy do geologists use?
Answer: Geologists use seismic waves to locate the center of an earthquake.
Which statement best describes a surface wave?
Which statement describes a surface wave? A surface wave is a wave that moves along the interface of two different materials, like air and water.
What describes a surface wave?
In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. A common example is gravity waves along the surface of liquids, such as ocean waves. Elastic surface waves can travel along the surface of solids, such as Rayleigh or Love waves.
Which explanation best describes the development of a wave?
Answer: The development of a wave is the friction between the moving air and the underlying water imparts energy, which causes the water to move in a circular motion, but the energy moves great distances. Explanation: Wave is a disturbance that travels through a medium.
Which type of radiation has the most energy?
Which type of radiation is the easiest to block?
Which type of radiation is least penetrating?
