How to use lithosphere in a sentence

Looking for sentences and phrases with the word lithosphere? Here are some examples.

Sentence Examples We believe that many Mesozoic and Cenozoic obducted ophiolite belts of SE Asia are fragments of fore-arc or back-arc lithosphere. Melts of these metasomites were volatile rich and hence ascended rapidly through the lithosphere, forming the lamprophyre magmas. In plate tectonics, a transform fault is a strike-slip fault extending throughout the lithosphere and joining any two other plate margins. After obduction, there was a slow rate of subsidence, which reflects the continuing cooling of the underlying Indian lithosphere after rifting. As you pull the lithosphere apart, as it separates, decompression occurs in the earth's mantle underneath the spreading centre. Slow and highly attenuating lithosphere exists beneath this portion of the Anatolian plate and geometry of the Benioff zones. After new oceanic crust forms, the lithosphere cools and thickens as it moves away from the ocean ridge. The differences between them arise as a result of the differences in strength and density of oceanic and continental lithosphere. Scientists believe that below the lithosphere is a relatively narrow, mobile zone in the mantle called the asthenosphere. This requires the removal of 80-100 km of Archaean lithosphere since Mesozoic time. Across the ridge, the asymmetric flow pattern in the asthenosphere will cause differential drag at the base of the lithosphere. It starts with the lithosphere, goes on to atmosphere and hydrosphere, and ends up with the biosphere. An alternative to an active mantle thermal anomaly is greater stretching of the mantle lithosphere than the crust. This allows us to place much tighter constraints on the tectonic and thermal evolution of the lithosphere during late orogenic extension than has previously been possible. The near-constant depth of the abyssal sea floor indicates that the lithosphere thickens to roughly 100 km in 70 million years, but then ceases to grow. Diamonds are most commonly associated with Archean subcontinental lithosphere but nanodiamonds were recently reported from mantle xenoliths in EM1like Hawaiian basalts. For example, the discovery of hydrothermal vents in the 1970s offered a clear proof of significant dynamic connections between the lithosphere, hydrosphere and biosphere. These igneous rocks record the extensive magmatism that resulted from northward subduction of Neotethyan oceanic lithosphere beneath the Lhasa terrane. The lithosphere is the rigid outermost layer of the geosphere. Because the radioactive source of heat is deep within the mantle, the fluid asthenosphere circulates as convection currents underneath the solid lithosphere. Show More Sentences The lithosphere is cooler and more rigid, while the asthenosphere is hotter and flows more easily. Somehow, this energy must be transferred to the lithosphere for tectonic plates to move. Bostrom presented evidence for a general westward drift of the Earth's lithosphere with respect to the mantle. The foreland basin forms ahead of the orogen due mainly to loading and resulting flexure of the lithosphere by the developing mountain belt. The depth, shape and size of a basin depend on tectonics, movements within the Earth's lithosphere. When the lithosphere keeps subsiding, new accommodation space keeps being created. Due to divergent movement, the lithosphere is stretched and thinned, so that the hot asthenosphere rises and heats the overlying rift basin. When the basin grows due to continued stretching of the lithosphere, the rift grows and the sea can enter, forming marine deposits. When a piece of lithosphere that was heated and stretched cools again, its density rises, causing isostatic subsidence. Earth's lithosphere is divided into several rigid tectonic plates that migrate across the surface over periods of many millions of years. The mechanically rigid outer layer of Earth, the lithosphere, is divided into pieces called tectonic plates. The crust and the relatively rigid peridotite below it make up the oceanic lithosphere. This bulge is thought to be caused by upward convective forces in the asthenosphere pushing the oceanic crust and lithosphere. The oceanic lithosphere in the area is directly related to the opening of the North Atlantic Ocean and one of the oldest preserved on Earth. When oceanic plates diverge, tensional stress causes fractures to occur in the lithosphere. In this model, the seabed height is determined by the oceanic lithosphere temperature, due to thermal expansion. A passive margin is the transition between oceanic and continental lithosphere that is not an active plate margin. A passive margin forms by sedimentation above an ancient rift, now marked by transitional lithosphere. The transition between the continental and oceanic lithosphere that was originally created by rifting is known as a passive margin. This refers to whether a crustal boundary between oceanic lithosphere and continental lithosphere is a plate boundary or not. Show More Sentences While a weld between oceanic and continental lithosphere is called a passive margin, it is not an inactive margin. The lithosphere beneath passive margins is known as transitional lithosphere. The very thin lithosphere beneath the rift allows the upwelling mantle to melt by decompression. Heating reduces the density of the lithosphere and elevates the lower crust and lithosphere. In addition, mantle plumes may heat the lithosphere and cause prodigious igneous activity. The accumulation of sediments above the subsiding transitional crust and lithosphere further depresses the transitional crust. The great thickness of the lithosphere requires that this bending be gentle. These form where fluids released from the downgoing plate percolate upwards and interact with cold mantle lithosphere of the forearc. To say that the lithosphere floats on top of the asthenosphere suggests a degree of easy buoyancy that isn't quite right. A second order control on trench depth is the age of the lithosphere at the time of subduction. The subduction process consumes older oceanic lithosphere, so oceanic crust is seldom more than 200 million years old. Seamounts provide data on movements of tectonic plates on which they ride, and on the rheology of the underlying lithosphere. The remainder appear to originate in the upper mantle and have been suggested to result from the breakup of subducting lithosphere. This is because the age of the oceanic lithosphere provides a major control on the depth of the ocean basins, and therefore on global sea level. That is, the subducted lithosphere is always oceanic while the overriding lithosphere may or may not be oceanic. Subduction zones exist at convergent plate boundaries where one plate of oceanic lithosphere converges with another plate. It is at subduction zones that Earth's lithosphere, oceanic crust, sedimentary layers and some trapped water are recycled into the deep mantle. Seismic tomography has helped detect subducted lithosphere in regions where there are no earthquakes. The thick lithosphere predicted by these models appears to be inconsistent with even a low level of ongoing volcanism and tectonism. The lithosphere likes to float on the aesthenosphere, the soft mobile voice of the unseen. Show More Sentences Most of this water is trapped in pores and fractures in the upper lithosphere and sediments of the subducting plate. Transform faults are also referred to as conservative plate boundaries, as lithosphere is neither created nor destroyed. A fault that passes through different levels of the lithosphere will have many different types of fault rock developed along its surface. The weight of the redistributed surface mass loaded the lithosphere, caused it to flex and also induced stress within the Earth. Water is driven out of the oceanic lithosphere in subduction zones, and it causes melting in the overlying mantle. Temperature increases also may contribute to the melting of lithosphere dragged down in a subduction zone. A rift is a region where the lithosphere extends as two parts of the Earth's crust pull apart. As the rift expands, the rift flanks lift up due to isostatic compensation of the lithosphere. Continents sit on continental lithosphere which is part of tectonic plates floating high on Earth's mantle. Oceanic crust is also part of tectonic plates, but it is denser than continental lithosphere, so it floats low on the mantle. This holds true for Australia, which sits on its own continental lithosphere and tectonic plate. In geology, a rift is a linear zone where the lithosphere is being pulled apart and is an example of extensional tectonics. Segment lengths vary between rifts, depending on the elastic thickness of the lithosphere. At the same time, the mantle lithosphere becomes thinned, causing a rise of the top of the asthenosphere. Deformation of continental lithosphere can take place in several possible modes. During the first stage, the oceanic lithosphere subducted from NE to SW under the subcontinental crust. This vertical stress is supported by the mantle and the flexure of the lithosphere. Tectonic plates are composed of oceanic lithosphere and thicker continental lithosphere, each topped by its own kind of crust. Tectonic plates are able to move because the Earth's lithosphere has greater mechanical strength than the underlying asthenosphere. The outer layers of the Earth are divided into the lithosphere and asthenosphere. Show More Sentences Tomographic images of the Iberian subcrustal lithosphere and asthenosphere. These reactions generate and define endogeny, their silicon furnishing the basis for continental shields and lithosphere generally. Environment refers to everything that surrounds us and consists of the lithosphere, hydrosphere, atmosphere, and biosphere. Because oceanic lithosphere cools and thickens as it ages, it subsides. The mantle lithosphere below the thinned and faulted continental oceanic transition cools, thickens, increases in density and thus begins to subside. Lithospheric thinning also allows the asthenosphere to rise closer to the surface, heating the overlying lithosphere by conduction and advection of heat by intrusive dykes. The lithosphere thins seaward as it transitions seaward to oceanic crust. In the smooth areas the lithosphere is more magmatic in composition. Current research indicates that complex convection within the Earth's mantle allows material to rise to the base of the lithosphere beneath each divergent plate boundary. The crust and the cold, rigid, top of the upper mantle are collectively known as the lithosphere, and it is of the lithosphere that the tectonic plates are composed. This volcanic arc was formed above a subduction zone where the oceanic lithosphere of the Iapetus Ocean subducted southward under other oceanic lithosphere. What exactly happens in a specific orogen depends upon the strength and rheology of the continental lithosphere, and how these properties change during orogenesis. Geologists attribute the arcuate structure to the rigidity of the descending plate, and island arc cusps relate to tears in the descending lithosphere. Major isostatic adjustments of the lithosphere during the Quaternary glaciation were caused by the weight of the ice, which depressed the continents. Abyssal hills are formed by stretching of the oceanic lithosphere. It has generally been accepted that tectonic plates are able to move because of the relative density of oceanic lithosphere and the relative weakness of the asthenosphere. In this way, the total surface of the lithosphere remains the same. Although volcanoes are technically part of the lithosphere, which itself is part of the climate system, the IPCC explicitly defines volcanism as an external forcing agent. The Earth's outer solid layer, the lithosphere, is made of rock. Since the mantle and the lithosphere continuously respond to the changing ice and water loads, the state of stress at any location continuously changes in time. Show More Sentences At the onset of rifting, the upper part of the lithosphere starts to extend on a series of initially unconnected normal faults, leading to the development of isolated basins. Where the oceanic crust is subducted under a continental plate sediments will be carried down to warmer zones in the asthenosphere and lithosphere. Atomic mass of an element in Table of Elements is presented by the average atomic mass of all stable isotopes of the element with taking their content in the lithosphere. Relative depth may be controlled by the age of the lithosphere at the trench, the convergence rate, and the dip of the subducted slab at intermediate depths. Examples from Classical Literature Our globe is a cooling and contracting body, and depression must always be the prevailing movement of the lithosphere. Thus were formed the oceanic basin and the continental arches of the lithosphere. The lithosphere is the more or less stable crust of the earth, which may have been, to begin with, about fifty miles in thickness. The accompanying figure shows the boundaries of lithosphere plates that are presently active. These igneous rocks were consolidated either upon the surface of the lithosphere or in its interior. Above the metallic core of the planet, the lithosphere consists exclusively of fluorides of the metals. The dark, cold abysses of the ocean are far less affected by change than any other portion of the surface of the lithosphere. Find more words!
