Earth’s seismic waves pass through it as it is also a low velocity zone. The temperature and pressure of the asthenosphere are so high that … ata means a pressure reading in technical atmosphere units (at) which are referenced to a perfect vacuum (absolute). = 1000 kg/m39.8m/s10m. Equivalent values for 1 at in other pressure units can be found in the list below. Calculate the absolute pressure and the fluid pressure. Kilopascal (kPa) is a frequently used pressure unit and equals to 1000 newton per square meter (metre). What is the temperature at a depth of 5000 km? Atm (Atmospheric Pressure) Conversion: An atmosphere (atm) equals to the air pressure at the sea level at a temperature of 15 Celsius. ( Log Out / Pascal is the unit of pressure in the metric system and is equal to 1 newton per square meter. There are tectonic plates on it that are in constant movement and work by means of a convection system. The Lithosphere is thinner and made of basalt. The heat that radiates flows into the earth. Because of the immense pressure from the overlying layers, the strength of this layer increases with depth. The convection currents that have their origin in this layer are very important because they are the ones that define the different movements of the plates. It is formed by iron and magnesium silicates. ... What is the pressure at a depth of 3500 km? Within it, a phenomenon called convection currents occurs. The mantle is one of the four chemical layers of Earth. Temperature in these layers is 200-400 Degrees Celsius, and 500-1000 Degrees Celsius. • High temperature and pressure: 500-900°C (932-1652°F) at the boundary with the crust; over 4000°C (7230°F) at the boundary with the core. The asthenosphere (from Greek asthenēs 'weak' + sphere) is the mechanically weak ductily-deforming region of the upper mantle of the Earth. Also its importance lies in the tectonic plates that are located in it because it collaborates with the movement of the continental masses with respect to each other, due to plate tectonics. On it floats the lithosphere, which is a rigid layer that is composed by the external part of the mantle and by the terrestrial crust allowing the tectonic plates to move. Atmosphere, hydrosphere, lithosphere, mesosphere, stratosphere, troposphere. This layer is slightly like plastic. megabar, megapascal (MPa), meter of air, microbar, micropascal, millibar, millimeter of mercury, millipascal, millitorr, nanobar, nanopascal, These layers are the Lithosphere and the Asthenosphere. ( Log Out / Why are fossil dates not always accurate? It lies below the lithosphere, at depths between 100 and 200 km (~ 62 and 124 miles) below the surface, but perhaps extending as deep as 400 km (~ 249 miles). However the unit has been largely phased out and the average atmospheric pressure is now mostly defined as 1 atm (101325 Pa) for weather and aviation or more coomonly 1 bar (100,000 Pa) for industrial and general purposes. Outer core. Another important function is that it contains the magma that volcanoes expel when they erupt. Join Yahoo Answers and get 100 points today. The density of this layer is 3.3-5.5 grams per centimeter cubed. 6200 °C Unlike all the other mechanical layers, the outer core is the only one made out of liquid— melted Fe-Ni alloy, to be exact. ‣ There are two types of crust: ‣ Continental crust which is made of a very thick layer of the rock granite and is less dense (2.7 g/cm3) ‣ Oceanic crust which is made How do scientists attempt to get the most This layer is the innermost layer in Earth, and is completely solid. The at pressure unit can be occasionally found on water resistant watches to indicate the maximum depth rating, particularly on European brands. A) core properties B) atmospheric structure C) asthenosphere location D) continental-crust thickness 27.Geologists have used information about the … The crust is the first chemical layer on Earth, and has a pressure of 1 atm. The asthenosphere boundary is primarily defined by temperature, and it starts when the crust heats up to 1300° C. In the same way, the materials in the higher zones cool down, and for this reason, these materials will descend. 4. The asthenosphere is the denser, weaker layer beneath the lithospheric mantle. Earth's lithosphere is thinner than its asthenosphere. The pressure units in the pressure converter, "atmosphere (atm, standard), atmosphere (technical), attobar, attopascal, bar, barad, barye, centimeter of mercury (0°C), centimeter of water (4°C), centibar, centipascal, centipascal, centitorr, decibar, The asthenosphere is part of the upper mantle located below the crust of the earth. What is meaning of “ata” and how does it convert into kgf/sq.cm? It is responsible to create new earth crust, which means that new lands will be produced. Atmospheric pressure, also known as barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The pressure in this layer is 1,485 atm, and has an average temperature of 2,900 Degrees Celsius(5,252 Degrees Fahrenheit). The 6 layers are the Crust, Mantle, Outer Core, Inner Core, Lithosphere, and the Asthenosphere. The asthenosphere is composed of semi-fused and solid materials at the same time. Change ), You are commenting using your Google account. This is the region that has the highest viscosity rate and mechanically is very weak with respect to the top layer of the Earth. Because of their temperature and pressure conditions the rocks become ductile and move slowly, measuring thousands of kilometers. We and our partners share information on your use of this website to help improve your experience. The asthenosphere (Ancient Greek: ἀσθενός [asthenos] meaning "without strength", and thus "weak", and σφαίρα [sphaira] meaning "sphere") is the highly viscous, mechanically weak and ductile region of the upper mantle of Earth.It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface.. Technical Atmosphere is some times written as ‘ata’ which is the short way of writing ‘at absolute’. What is a real life example of compressional stress? It lies below the lithosphere, at depths between 100 and 200 km (~ 62 and 124 miles) below the surface, but … Pressure in this layer is 2,961 atm. To convert any pressure unit into Technical Atmospheres click on the relevant unit below. I will continue with this set soon. 1) Enter a valid value into the input field below. Density Range (g/cm3) Pressure Range (millions of atmospheres) Temperature Range (˚C) Mantle 3.4 - 5.6. The asthenosphere (Ancient Greek: ἀσθενός [asthenos] meaning "without strength", and thus "weak", and σφαίρα [sphaira] meaning "sphere") is the highly viscous, mechanically weak and ductile region of the upper mantle of Earth.It lies below the lithosphere, at depths between approximately 80 and 200 km (50 and 120 miles) below the surface.. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ; 1,013.25 mbar ), which is equivalent to 760 mm Hg , 29.9212 inches Hg , … Its average temperature is 6,650 Degrees Celsius(12,002 Degrees Fahrenheit). The asthenosphere is a layer of great geological importance to the Earth’s mantle. 2015 - asknumbers.com. ‣ As you travel deeper down, from the crust to the inner core, the temperature increases. This layer ranges from a depth of 80km to 250km below surface, and is considered a cooler environment than its neighbour (asthenosphere), approximately 400 degrees Celsius. It is also another chemical layer of Earth. Solution: Pfluide= Pgauge = rgh. Unlike the asthenosphere, the mesosphere is much stronger and flows with more resistance. Check all that apply. This is due to the fact that in its composition we find a very important component called basalt, which is an igneous rock that, through an extrusion process, flows through the oceanic ridges. The asthenosphere is the top of the Earth's mantle located below the lithosphere. On it, tectonic plates move. Pressure conversion calculator for several SI (metric) and other frequently used pressure units. The asthenosphere is responsible for collecting heat from the mesosphere and projecting it into the lithosphere through a convection system, which can be compared to the boiling water process. The rocks in the asthenosphere are not as dense as the rocks in the lithosphere. In contrast, lithospheric rocks contain more silica, but less aluminum, sodium, and potassium. It is a layer of solid rock where the extreme pressure and heat cause the rocks to flow like a liquid. The asthenosphere (from Greek asthenēs 'weak' + sphere) is the mechanically weak ductily-deforming region of the upper mantle of the Earth. Send us your enquiry for a product associated with this at – Technical Atmosphere Pressure Unit page, and get assistance with selecting a product for your application. This causes the materials to be in continuous motion, causing an important effect on tectonic plate motion. The asthenosphere is the layer of the Earth that lies below the lithosphere. On it floats the lithosphere, which is a rigid layer that is composed by the external part of the mantle and by the terrestrial crust allowing the tectonic plates to move. reliable date possible. It ranges between 80km-200km in thickness and solidity depending on the region (for example around the mid ocean ridge the asthenosphere is liquid due to the high temperature).
