(found close to source) moves fast, lava that hardens into rough, jagged rocks with a crumbly texture. the generally twice daily rise and fall of sea level that result from the gravitaional balance between the sun and the moon. Flashcards. Seismogram . A plate boundary where two plates move past each other in opposite directions. The Rayleigh wave is important in engineering studies because of its simplicity and because of the close relationship of its velocity to the shear-wave velocity for earth materials. Those areas more than 105 degrees from an earthquake focus where no S-waves are recorded. measure the time between P and S waves. These are surface waves, meaning they cant travel through the body of a material unlike the P and S. This makes them so destructive. (1000-1200 c) dark colored due to low silica, moves fast, low viscosity, most distructive, -Low temperature. They are called surface waves because their amplitude decreases exponentially with increasing depth. All surface waves travel slower than body waves and Rayleigh waves are slower than Love waves. Further out is older rock. Introduction. Compare and contrast properties and mechanics of P, S, and Surface waves [Insert brief introductory statement here.] True/false - Boundaries that are greater than 300 km deep are convergent. ; There are two types of body waves, P-waves and S-waves. Because it rolls, it moves the ground up and down, and side-to-side in the same direction that the wave is moving. The main types of seismic waves: P, S, and surface waves Seismic waves can either be body waves or surface waves -- but the full story is far more complex. Terms in this set (38) ordinary beach waves are created by the interaction of ____ with the _____ hydrosphere, atmosphere. Geology. T/F: lithosphere is destroyed as a result of a convergent boundary, T/F: lithosphere is destroyed from a transform boundary, T/F: lithosphere is destroyed from a divergent boundary, the movement of a fluid, caused by differences in temperature, that transfers heat from one part of the fluid to another, all continents of the southern hemisphere were connected. Rock, in geology, naturally occurring and coherent aggregate of one or more minerals. seismic waves that travel through the Earth's interior. The large-scale circulation of these surface currents roughly mirrors the large-scale circulation of air, which most simply derives from unequal heating of the planet’s surface by the sun. There are two types of surface waves, Rayleigh waves and Love waves. Destructive waves destroy beaches. The outcome for this section will be covered by this Open Educational Resource. Geology. the surface of the Earth). Plates move apart and magma comes up to fill the gap which forms volcanoes, rift valleys, new crust, Plates move towards each other, subduction when the denser oceanic plate is forced below the continental plate, forms ocean trenches, mountain ranges, and volcanoes. ; Surface waves, which are analogous to water waves, travel just beneath the Earth's surface. The waves that travel along the surface are slower, but they are responsible for the earthquake's damaging effects. Played 0 times. Seismology (/ s aɪ z ˈ m ɒ l ə dʒ i /; from Ancient Greek σεισμός (seismós) meaning "earthquake" and -λογία (-logía) meaning "study of") is the scientific study of earthquakes and the propagation of elastic waves through the Earth or through other planet-like bodies. Match. The shock waves spreading out from an earthquake are called seismic waves (from the Greek word for earthquake). Included are sciences such as mineralogy, geodesy, and stratigraphy. Spell. When waves moving out from one storm center meet up with waves generated by another source the energy carried by these waves interacts to produce a net change in the elevation of the sea surface. On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. depositional evidence could be found on both sides of the spreading center, A deep valley that forms where two plates move apart. velocity in Earth. Discipline of Geology, 2019) Over the last decades, seismic surface-wave studies have produced increasingly detailed images of the Earth s structure at a regional scale. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. 146 times. A volcanic vent formed by the explosive escape of gases and often filled with breccia. volcanoes that are not (typically) associated with plate boundaries other than to provide evidence of a plate shift (see picture). Hot springs occur when ground water circulates near magma chambers and is heated. Confined to the surface of the crust, Love waves produce entirely horizontal motion. Geology. Surface waves can be understood as a superposition of free oscillations. Wave Action DRAFT.

Body waves travel through the interior of the Earth. 10th - University. What is a wave? Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves). In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. Types. Play this game to review Geology. ), a small earthquake that follows the main earthquake, the point of initial movement (below surface), geographic point on Earth's surface directly above the focus. false. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. As waves continue to hit the beach there is more running water to transport the material out to sea. : 48–50: 56–57 Other modes of wave propagation exist than those described in this article; though of comparatively minor importance for earth-borne waves, they are important in the case of asteroseismology. Earthquakes generate four principal types of elastic waves; two, known as body waves, travel within the Earth, whereas the other two, called surface On the other hand, surface waves propagate only at the interface between two different media, like the interface between Earth and atmosphere (i.e. A common example is gravity waves along the surface of liquids, such as ocean waves. typically the most violent, explosive gasses are trapped. Ocean waves are caused by wind moving across the surface of the water. Body waves travel through the Earth's interior. In physics, a surface wave is a mechanical wave that propagates along the interface between differing media. Related Articles: Glossary: Love wave; Glossary: Rayleigh wave; 9 Crustal Deformation and Earthquakes It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. The waves are usually very high, have a short wavelength and are very frequent. They usually result from distant winds or geologic effects and may travel thousands of miles before striking land. Physical Geology- waves and shorelines + geological time. Each number goes up by 10X from the previous. Rayleigh waves are characterized by vertical motion of the ground surface, like waves on water, while Love waves are characterized by horizontal motion. Gravity waves can also occur within liquids, at the interface between two fluids with different densities. Save. There are two types of surface waves, Rayleigh waves and Love waves. dispersion. What causes ocean waves? In rare cases, part of the ocean floor will be uplifted as a convergent boundary scrapes pieces of the ocean up onto the continental margin. In physics, a surface wave can refer to a mechanical wave that propagates along the interface between differing media, usually two fluids with different densities. They usually result from distant winds or geologic effects and may travel thousands of miles before striking land. A tide at its highest point in which the difference between high and low tide is the greatest. Geography. Edit. T/F: The more the silica in magma, the lower the viscosity. Evaluation for Seismic Waves DRAFT. Geology study guide What are the properties of P-waves, S-waves and surface waves? Whereas this is true for acoustic surface waves or certain classes of seismic waves, for example, it is generally not true for the phenomenon that we are discussing here. this travels as an S wave in the inner COre, we can now interpret the 3-D structure of the Earth in terms of very slight (2-4%) variations from that simple 4-layer model, NOTE: to better than 96% accuracy, seismic velocity varies only with depth. 0% average accuracy. When body waves (P or S) reach Earth’s surface, some of their energy is transformed into surface waves, of which there are two main types, as illustrated in Figure 11.14. An introduction to the geochemical and geophysical sciences logically begins with mineralogy, because Earth’s rocks are composed of minerals—inorganic elements or Rayleigh waves are set off by the combined effect of P- and S-waves on the earth’s surface. acquire readings from three or more seismographic stations. Surface waves. This is known as the sudden shaking of the ground and known as the source of seismic waves. Elastic surface waves can travel along the surface of solids, such as Rayleigh or Love waves. Earthquake - Earthquake - Properties of seismic waves: At all distances from the focus, mechanical properties of the rocks, such as incompressibility, rigidity, and density, play a role in the speed with which the waves travel and the shape and duration of the wave trains. surf.
