c. The half-life of carbon-14 is so short that it can only be used to date materials that are less than 70,000 years old. 17.1 Waves Waves form on the ocean and on lakes because energy from the wind is transferred to the water. 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. Surface wave definition, a seismic wave that travels along or parallel to the earth's surface (distinguished from body wave). The waves that travel along the surface are slower, but they are responsible for the earthquake's damaging effects. Rayleigh waves are named after Lord Rayleigh (John Strutt), an English aristocrat who, in his work as a scientist and mathematician, developed a detailed mathematical accounting of the type of surface wave named after him. Geography. Love, a British mathematician who worked out the mathematical model for this kind of wave in 1911. 2 years ago. The waves are usually very high, have a short wavelength and are very frequent. T/F: basaltic lava is a type of mafic lava, True, low silica (this means it moves slow and is prone to explosions ** double check this), T/F: adesiteic lava is a mixture of basalatic and rhyolitic. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. magma with a high silica content and large volume of gas (explosive eruptions), magma that is silica poor, low viscosity, releases volatiles, high density, high temperature, tiny particles of pulverized volcanic rock and glass (<2mm), a pyroclastic igneous rock that consists of fragments of volcanic debris, which either fall through the air and accumulate, or form when solidifying lava breaks up during flow, A violent, explosive volcanic eruption like a steam-boiler explosion, occurring when subsurface water is heated and converted to steam by hot magma underground. The other kind of surface wave is the Rayleigh wave, named for John William Strutt, Lord Rayleigh, who mathematically predicted the existence of this kind of wave in 1885.A Rayleigh wave rolls along the ground just like a wave rolls across a lake or an ocean. Search for: Reading: Surface Waves. At her location, approximately 500 miles away from the Virginia residents who had first mentioned it, the quake was barely perceptible. A few minutes before 2 p.m. that day, reports of an earthquake in Virginia began to show up in her feed. Body waves travel through the interior of the Earth. false. 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. The stronger the wind, the longer it blows, and the larger the area of water over which it blows (the fetch), the larger the waves are likely to be.. Surfaces waves-only travel near earths surface-larger and more destructive 1) snake 2) elliptical. The backwash has less time to soak into the sand. Mafic lava, before cooling, has a low viscosity, in comparison with felsic lava, due to the lower silica content in mafic magma. Seismographs record the amplitude and frequency of seismic waves and yield information about the Earth and its subsurface structure. volcanoes that are not (typically) associated with plate boundaries other than to provide evidence of a plate shift (see picture). spring tide. free surface waves we need to understand the boundary conditions on the free surface, any bodies under the waves, and on the sea floor: –Pressure is constant across the interface –Once a particle on the free surface, it remains there always. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water.

Geology - Geology - Study of surface features and processes: Geomorphology is literally the study of the form or shape of the Earth, but it deals principally with the topographical features of the Earth’s surface. Two types of surface waves are Rayleigh waves and Love waves (Figure 12.9). It's the fastest surface wave and moves the ground from side-to-side. form by the interference of traveling waves, have *, where the waves destructively interfere (zero amplitude, no motion), where the waves constructively interfere (large amplitude, back and forth), the longer the string, or tube, or slinky (or the longer the distance a wave travels within a layer), the *, P and S waves in a stack of layers, within the top layer is a short distance, so high frequency *, while the waves are reverberating and interfering vertically, they are also moving outward horizontally, result, low frequencies arrive first, can measure dispersion of surface waves at Earth's surface, gives an indirect message of P and S wave velocity at depth (working from top down), gives us a measure of the incompressibility and rigidity of the Earth's layers, the number of cycles in one second (this is 1/Period), interference phenomenon between traveling waves, which appears stationary (doesn't "travel"), points of destructive interference (no motion of standing wave), each discrete pattern of standing wave, distinguished by the number of nodes, 2 layers;boundary is "the Moho", the upper layer has P-wave velocity of 6 km/sec, the lower layer has a P wave velocity at its top of 8 km/sec, thickness of the crust varies from about 7 km under the oceans to 80 km beneath mountain belts, the core must have slower velocity than the lowest part of the mantle *, Inge Lehmann (Danish woman who worked with Gutenberg), 1936, looked into those fast P waves that arrive within the P shadow zone, there must be an INNER CORE which has faster velocity than the OUTER CORE, 1972, asserted he could identify a PKJKP wave following the PKIKP wave. It is an interesting characteristic of waves that the movement of two such individual wave trains is completely independent of and unaffected by that of the other wave train. In late August of 2011, a Twitter user in New England had a surprising experience. Rayleigh waves are set off by the combined effect of P- and S-waves on the earth’s surface. ex: Mauna loa (normal volcano) lava moves very far, very fast, rhyolitic lava (high vis, comes out like toothpaste, a composite volcano whose top collapses into the magma chamber (Yellowstone).

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. increases with depth *high-frequency surface waves "sample" only the slower upper layers, low frequency surface waves "sample" the entire stack*. Recall S wave is half the velocity of the P wave. STUDY. Introduction. An introduction to the geochemical and geophysical sciences logically begins with mineralogy, because Earth’s rocks are composed of minerals—inorganic elements or (further from source) moves slow, Lava that cools underwater, taking on a distinctive pillow-like shape as it hardens (crystalline structure), shield, volcanic dome, cinder cone, stratovolcano, caldera, is composed of basaltic lava. 2. Body waves travel through the interior of the Earth. Rocks are commonly divided into three major classes according to the processes that resulted in their formation. There are two types of surface waves, Rayleigh waves and Love waves. No substances on Earth contain significant amounts of carbon-14. As waves continue to hit the beach there is more running water to transport the material out to sea. 6 km/s (Compressional), a secondary wave, or shear wave; a seismic wave that causes particles of rock to move in a side-to-side direction perpendicular to the direction in which the wave is traveling. A volcanic vent formed by the explosive escape of gases and often filled with breccia. What are the 4 main types of erosion? 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. 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. Body waves are of two types: Primary waves (also called P-waves, or pressure waves) and Secondary waves (S-waves, or shear waves). 146 times. the surface of the Earth). Rock, in geology, naturally occurring and coherent aggregate of one or more minerals.
