Point 1 is the focus, Point 2 is the epicenter, and Line 3 is the fault. [17] The Zenneck surface wave, which is a non-radiating guided-wave mode, can be derived by employing the Hankel transform of a radial ground current associated with a realistic terrestrial Zenneck surface wave source. Advertisements for a certain small car claim that it floats in water. Surface waves travel near the surface or above the surface of the Earth. Which statement describes the focus of an earthquake? As previously described, their motion is typically transverse, longitudinal, or a combination of both. It is a remnant that provides an important source of data on the primordial universe. A transverse wave causes particles to move perpendicular to the direction it travels, while a longitudinal wave causes particles to move parallel to the direction it travels. All rights reserved. d. It conducts electrical current too well to be pure iron. (e) They occur at Earth's surface. Secondary waves travel through solid medium and their speed is less than the "P" waves.

(1 point) Responses -The speed of sound is generally faster in solids than in gases, because solids are denser than gases.- 2.) Seismic wave reflection has helped scientists identify: The general compositions, respectively, of the upper continental crust, lower continental crust, and ocean crust are: Information about the mantle comes primarily from: How do scientists know that the outer core is not pure iron? Gravity waves are caused in the air by disturbances, including mountains and thunderstorms. answer choices Sound waves and P-waves are longitudinal waves, while light waves are transverse waves. Seismic tomography suggests that Earths mantle exhibits: Which is thought to change the composition of the outer core enough to produce convection? These remains are known as: d. Its density varies randomly with depth. a. They arrive at the same time. They are generated by movements in Earths crust. 1. [6] Sommerfeld-Zenneck surface waves predict that the energy decays as R1 because the energy distributes over the circumference of a circle and not the surface of a sphere. (b) At what distance from the speaker would the sound be barely audible? To visualize a longitudinal wave, imagine compressing one end of a spring and letting it go. When these waves enter a fluid medium, however, their motion and velocity change. Which word identifies the shaking that results from movement under Earth's surface? b. A little over a minute later, a mild earthquake rocked her own city. Love waves have transverse motion (movement is perpendicular to the direction of travel, like light waves), whereas Rayleigh waves have both longitudinal (movement parallel to the direction of travel, like sound waves) and transverse motion. I would definitely recommend Study.com to my colleagues. They have two kinds of movement. For seismic surface waves, this is typically the boundary between rock and air at the earth's surface. C Mechanical waves require a medium to travel through. His theory purported to explain every feature of the auditory sensation owing to these passive mechanical phenomena. C. Plates of lithosphere are gradually moving. Love. d. A combination of different convection methods, d. Conduction of heat from the inner core, a. They are generated by movements in Earths crust. Earthquakes are usually caused when rock underground suddenly breaks along a fault. Express the following in partial fractions: 2x2+85x+3620x3+47x2+11x6\frac{2 x^2+85 x+36}{20 x^3+47 x^2+11 x-6} 2. They result in much ground motion. All three scales provide useful information in measuring and analyzing earthquakes across the globe. Amount of damage can be used to determine intensity. Love waves have a back-and-forth motion, like a sidewinder rattlesnake traveling over the sand. The power output of a certain public-address speaker is 6.00 W. Suppose it broadcasts equally in all directions. A.) Tiffany has worked on science curriculum and lesson writing since 2015. light waves and P-waves are transverse waves, while sound waves are longitudinal waves. Heat from the sun reaches Earth in the form of, Responses to absorb sound waves to absorb sound waves to transmit sound waves more clearly to transmit sound waves more clearly to increase the frequency of sound waves to increase the frequency. In transverse waves, the motion of the wave (i.e., the direction in which the particles being moved by the wave vibrate) is perpendicular to the direction the wave is traveling. What happens when stress builds at faults? Hope this helps! She taught geology courses while she was getting her MS and was a TA while at Carleton. D.). Point 1 is the epicenter, Point 2 is the fault, and Line 3 is the focus. This has led engineers to developing "shock absorbers" that allow more shaking and reduce the amount of damage to the building. The duck's motion, therefore, is transverse, as the wave is forcing it to move perpendicular to the direction it travels. A common example is gravity waves along the surface of liquids, such as ocean waves. They cannot travel through matter, but they can in a vacuum. Instead, each 'piece' of water rocks forward, up, back, and down, making one complete circle as a wave passes by. A backyard swimming pool with a circular base of diameter 6.00 m is filled to depth 1.50 m. (a) Find the absolute pressure at the bottom of the pool. Choose the box color(s) in the periodic table below that match(es) the following:\ Check all that apply. Hence, the statements describe the surface waves: They travel slower than P waves.

Which statement about the Mercalli scale is true? At her location, approximately 500 miles away from the Virginia residents who had first mentioned it, the quake was barely perceptible. They can travel through matter and in a vacuum. Water waves are a combination of both transverse and longitudinal motion, as the water particles move in a rolling motion, bobbing both up and down while moving forward in the direction the wave is traveling. A wave bounces off the surface of a material. If you could follow an individual particle of water under the influence of a surface wave, you would see that it's not being carried forward by the wave. Its electric field strength falls off at a rate of e-d/d in the direction of propagation along the interface due to two-dimensional geometrical field spreading at a rate of 1/d, in combination with a frequency-dependent exponential attenuation (), which is the terrestrial transmission line dissipation, where depends on the mediums conductivity. Two of the most important types are Rayleigh waves and Love waves. The speed of sound through diamond is, Responses to reflect sound waves better to reflect sound waves better to increase the frequency of sound waves to increase the frequency of sound waves to transmit sound waves more clearly to, Heat and pressure build up over time in the Earths core. This radiative ground wave is known as Norton surface wave, or more properly Norton ground wave, because ground waves in radio propagation are not confined to the surface.
