What are facts about the layers of the earth?
(All depths are from the surface of the Earth.) 1. The Crust--The outer skin of the planet is composed of igneous, metamorphic, and sedimentary rock. The crust is divided into continental or oceanic based on composition and formation. Continental Crust: Comprised predominately of rocks most resembling granite, the continental crust is relatively thick compared to the oceanic crust with a depth that ranges from 30 km to 50 km. The average specific gravity of continental crustal rock is 2.7. Oceanic Crust: At an average depth of 5 km to 10 km, the oceanic crust is thinner than the continental crust. Oceanic crustal rocks are composed mainly of the igneous rocks basalt, diabase, and gabbro, which are mafic in composition. The average specific gravity of oceanic crustal rock is 2.9. Lithosphere: See below. 2. The Mantle--The layer directly below the crust which is delineated from the crust by the Mohorovicic Discontinuity, where seismic waves increase in velocity. The division between the mantle and the crust is a chemical one, the rocks and constituent minerals being higher in magnesium and lower in silicon and aluminum than crustal rocks. The mantle comprises 84% of Earth's volume. The mantle can be further divided as follows: Upper Mantle:Lithosphere: The uppermost mantle consists of hard rock and is attached to the crust and comprises the lithosphere. The lithosphere is comprised of tectonic plates which 'float' independently of each other. The lithosphere contains more mantle than crust. Oceanic lithosphere ranges from 50 km to 100 km in thickness, and continental lithosphere ranges from 40 km to 200 km. Asthenosphere: Just below the lithosphere lies the asthenosphere, an area of highly viscous but solid rock. Its viscosity allow it to move slowly over time, which it does as it transfers heat to the lithosphere via convection currents. These convection currents are responsible for the movement of Earth's tectonic plates. The depth of the asthenosphere averages somewhere between 100 km and 200km with depths up to 410 km. Transition Zone: The depth of the transition zone is between 410 km and 660 km. The rock here is mostly peridotite, a coarse grained igneous rock, kept from melting by extremely high lithostatic temperatures. Temperatures in the transition zone range from 1400 degrees C to 1600 degrees C. The Lower Mantle: The depth of the lower mantle ranges from 670 km to 2798 km. Little is known about the lower mantle other than that seismic waves indicate it is fairly homogenous in lithology. D'': The D'' area of the mantle extends from 2798 km to 2900 km, which is the boundary between the mantle and the liquid outer core. At this level, the pressures are enormous, roughly equal to 1.4 million units of atmospheric pressure, and temperatures are over 4,000 degrees C. 3. The Outer Core: The outer core lies at a depth from 2900 km to 5150 km. It's composed of liquid iron and nickel along with small amounts of lighter elements, with temperatures ranging from 4,000 degrees C to 6,100 degrees C near the boundary with the inner core. 4. The Inner Core: From the boundary with the outer core to the center of the Earth, a distance of about 1220 km is the solid sphere of the inner core, a ball of incredibly hot iron-nickel alloy. Temperatures here reach between 5,000 and 7,000 degrees C, and pressures are calculated to be around 3,000,000 units of atmospheric pressure. Despite the high temperature, at these pressures the metals cannot remain molten. == == == == === === == ==

What is the range of the depth of the asthenosphere?
The asthenosphere is the lower portion of the Earth's mantle. Its temperature ranges from 1000 degrees Celsius to 2500 degrees Celsius.
What depth would you find mantle material but still be in the Lithosphere?
yes
What does lithosphere mean in science terms?
lithosphere refers to the rocks of the earths surface and upper mantle or depth of plates. hope that helped
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
Where does Cooler older oceanic lithosphere sink?
Down into the mantle. At a depth of about 600 miles they become undetectable seismographicaly and are believed to have melted back into the mantle rock.
What is another name for the upper part of the mantle?
the upper part of the mantle is called the lithosphere. this layer also includes the crust.
Where does the lithosphere located?
The lithosphere is the hard rocky outer shell of the Earth, composed of the crust and uppermost mantle, that extends from the surface to a depth of up to 200 km at its deepest point.
Is the lithosphere and asthenosphere boundary above or below the Moho?
The boundary between the asthenosphere and the lithosphere is normally below the Moho (which marks the boundary between the crust and the mantle). The exception to this is below mid-ocean ridges where the moho and the lithosphere / asthenosphere boundary are at the same depth.
The deep mantle is composed of material with a lighter density than the outer mantle?
False. Density increases with increasing depth.
How is the temperature and pressure in the Earth's mantle related to the depth of the mantle?
The degree of temperature and exertion of pressure by the molten materials (magma) within the mantle is directly proportional to its depth. This means that, the deeper you go down the mantle the higher the degree of temperature and pressure exerted.
How far below the earth's surface is the asthenosphere?
The asthenosphere begins at around 100-150 km depth in the Earth. This is below the lithosphere, which consists of the crust and the uppermost mantle (the plates in plate tectonics).The asthenosphere is in the mantle, but it is still unclear how much of the mantle (which goes down to a depth of ~2900 km) is actually part of the asthenosphere.
What are Asthenosphere and lithosphere?
We speak of the Earth as consisting of three main regions; the crust as the solid outermost part, the inner core at the very center and the mantle in between. Then we give the regions where they come together names and we also subdivide the three main regions and give the subdivisions names.It is the lithosphere and the asthenosphere that are the parts of the surface moving when we talk of continental drift.The lithosphere is outer portion of the Earth. It is composed of the oceanic and continental crust, along with the rigid upper mantle.The asthenosphere is the plastic like upper mantle directly below the lithosphere where rock can move, bend, and deform without breaking. Below that, the mantle become more fluid and is the major part of the volume of the Earth.The inner most part, the core, is only about 15% of the whole Earth.
How many km is the Lithosphere?
The lithosphere can be 8 km to about 65km in depth.
