A few minutes before 2 p.m. that day, reports of an earthquake in Virginia began to show up in her feed. 7.1 A). A Love wave is a seismic surface wave that exhibits only side-to-side transverse motion as it travels through the rock. and cease repining; Behind the cloud is the sun still shining; Thy fate is a common fate of all, Into each life some rain must fall." Longfellow is rightrain comes at different times to all of us. They can travel through outer space. Answer. Surface waves, as the name implies, travel along the earth's surface solely through the crust. Which type of wave may make the ground roll? Which statement describes how geologists use data from seismographs to learn about earthquakes? Responses Write the chosen letters on a separate sheet of paper. Examples are the waves at the surface of water and air (ocean surface waves). Tiffany has worked on science curriculum and lesson writing since 2015. Which statement describes the damage that results from earthquakes? Which of these factors is involved in earthquake formation Brainly? When two blocks of rock or two plates are rubbing against each other, they stick a little. Which statement correctly describes the diagram? a. A little over a minute later, a mild earthquake rocked her own city. d. It conducts electrical current too well to be pure iron. Which statement correctly describes a property of sound waves; Which property is unique to electromagnetic waves? The _______________ of an earthquake refers to the breakage point of subsurface rock resulting in the creation of the epicenter. In physics, a surface wave can occur along any boundary of two different substances. Seismic waves from this earthquake are detected at a variety of seismographs worldwide. (C) They are produced by P and S waves. Correct answers: 1 question: Assessment Multiple Choice. (a) Within what distance from the speaker would the sound be painful to the ear? Any pond river lake ecosystem in our areas, Define the term unemployment rate and state four reasons for unemployment amongst the south african youth, . They can be controlled by the pull of gravity. Examples of different surface waves include the following: There are several different types of seismic surface waves but only two popular and common ones: Love waves and Rayleigh waves. D. The point an Earth's surface directly above the focus. A wave transfers its energy to a material A wave passes through a material. (1 point) Responses wave O wave M wave N wave L, 1. They require particles to transfer energy. They travel from the epicenter. Which statement best describes the . The seismic type of surface wave happens at the boundary between air and rockthe surface of the earth. Its like a teacher waved a magic wand and did the work for me. These waves are almost 1.7 times slower than P waves. As previously mentioned, surface waves can occur at the boundary of any two media. they arrive before s waves. Ground waves are radio waves propagating parallel to and adjacent to the surface of the Earth, following the curvature of the Earth. light waves and P-waves are transverse waves, while sound waves are longitudinal waves. B.) Speed. Surface waves Wind blowing over a calm lake surface first produces an effect that may appear as a widely varying and fluctuating ruffling of the surface. The combination of the Rayleigh waves' vertical rolling action and the horizontal stresses from the Love waves is the source of most direct damage from earthquakes (i.e., damage not caused by secondary effects like a fire or tsunami). Love waves have a back-and-forth motion, like a sidewinder rattlesnake traveling over the sand. 3 of 53 of 5 Items Question Use the information about four different waves to answer the question. Sound waves are mechanical waves that require a medium to travel through. Which refers to the number of wavelengths? Stress is dissipated through tectonic plate motion, b. This sudden release of energy causes the seismic waves that make the ground shake. (Source: US . They have two kinds of movement. What does the star represent on the Florida map? Which statement correctly describes Earths interior? A wave bounces off the surface of a material. 4.B (b) They arrive after P waves. C. a gas. . 2. While most surface waves are mechanical waves, which means they must travel through a specific material, some electromagnetic surface waves do exist. They require particles to transfer energy. Which type or types of motion is particle motion in surface waves? The rock on either side of the fault in a seismic gap is locked and stores rather than releases energy. I would definitely recommend Study.com to my colleagues. When these two motions are combined, a circular particle motion is created. Instead, they travel outward along the surface from the origin of the earthquake. Advertisements for a certain small car claim that it floats in water. Seismic surface waves have large amplitudes and leave massive destruction in their wake. They are waves that are able to pass through a vacuum. Intensity is a measure of the shaking and damage caused by the earthquake; this value changes from location to location. - Damage can be measured using the Richter scale.

An electromagnetic wave is a wave that does not require a medium through which to travel, and its motion is not displayed by the movement of particles within that medium. Strike-Slip Fault Overview & Types | What is a Strike-Slip Fault? While most are also mechanical waves, certain electromagnetic waves are also surface waves. 23, pp. As previously mentioned, some surface waves can travel through water. Two of the most important types are Rayleigh waves and Love waves. Secondary waves travel through solid medium and their speed is less than the "P" waves. _______________ are seismic waves that travel through the deep layers of the Earth. Therefore, the seismic waves that take that path are the first to arrive, and scientists call these the body waves. They are waves that require some form of matter as a medium. They cannot travel through matter nor in a vacuum. She has her Master's in Geology from the University of Illinois and a Bachelor's in Geology and Physics from Carleton College. Click the card to flip Definition 1 / 21 c. Responses B M 150 600 N 100 600 O 50 600 The table shows information about four waves. Try refreshing the page, or contact customer support. (b) Two persons with combined mass 150 kg enter the pool and float quietly there. In other words, this is not a wave that travels in a relatively straight line through the earth from the earthquake's focus, or breakage point of subsurface rock, to the observer's location. How is an echo formed? They can, 1.) A mechanical wave moves through a medium, which can be (1 point) A. a liquid. Barrier Island Formation & Examples | What is a Barrier Island? Which word identifies the shaking that results from movement under Earth's surface? They can travel on the surface of water. Responses Find the pressure increase at the bottom of the pool after they enter the pool and float. Jasmine, Hibiscus, Damiana, Kava Kava, Orange peel + Cannabis. In radio transmission, a ground wave is a guided wave that propagates close to the surface of the Earth.[1]. Which type of seismic wave is shown? Check all that apply. Which statement describes the Mercalli scale? Which factors are involved in earthquake formation? 233290, Dec 1899, Annalen der Physik, Vol. The deep mantle is denser than the lithosphere. Which statement correctly describes a property of sound waves? 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. Which statement best describes the reflection of a wave? Which phrase describes a feature of an earthquakes epicenter Brainly? The Richter magnitude scale was developed in 1935 by Charles F. Richter of the California Institute of Technology as a mathematical device to compare the size of earthquakes. Seismic waves carry energy through Earth and shake Earth below the seismograph These waves are elastic waves and are also known as shear waves. They arrive at the same time. They can shake structures on Earth. A., Mackay, T. G., and Lakhtakia, A., ", J. Zenneck, (translators: P. Blanchin, G. Gurard, . Picot), ", G. Goubau, ber die Zennecksche Bodenwelle, (, V. I. Babakov, V. N. Datsko, Yu. The deep mantle is hotter than the lithosphere. Most surface waves, such as water and Rayleigh waves, exhibit both transverse and longitudinal motion as they travel. (A) They often compare information from all over the world. C.) They can travel through outer space. Electromagnetic waves can also propagate as "surface waves" in that they can be guided along with a refractive index gradient or along an interface between two media having different dielectric constants. Most commonly, scientists use the term "surface wave" to refer to a wave that is generated by an earthquake and travels along the surface of the earth. (A) They often compare information from all over the world. Which statement best describes the movement of a longitudinal wave? Point 1 is the focus, Point 2 is the epicenter, and Line 3 is the fault.
