What is boundary between the mantle and outer core?
Gutenburg Discontinuity
What is the temperature of the Gutenberg discontinuity?
The Gutenberg discontinuity is located approximately 2,900 kilometers below the Earth's surface. At this depth, temperatures can reach up to 4,000 degrees Celsius (7,200 degrees Fahrenheit).
The liquid layer of earths core between mantle and inner core?
Gutenburg Discontinuity
What is a fact about the earths outer core?
The Earth's outer core is composed mainly of liquid iron (85 %) and nickel (5 %) with the rest made up of a number of other elementsThe outer core is 2,260 km thickThe outer core's upper boundary is 2,890 km (1,806 miles) below the surfaceThe outer core's lower boundary is 5,150 km (3,219 miles) below the surfaceThe temperature of the outer core varies from 4400 degrees C at it's upper boundary and 6100 degrees C at it's lower boundaryThe outer core accounts for approximately 31 % of Earth's mass The layer above the outer core is known as the mantle and the boundary itself is known as the Gutenberg discontinuity, named after the the German geophysicist Beno Gutenberg who discovered it. Gutenberg is also famous for his work with Charles Richter in the development of the Richter magnitude scale.The layer below the outer core is the inner core and this boundary was discovered by the Danish geophysicist Inge LehmannGeophysicists currently believe that the convection of the molten iron in Earth's outer core produces Earth's magnetic field which protects us from solar radiation and without which life on Earth as we know it would have been impossibleSome geophysicists also believe that certain mantle plumes form at the boundary between the outer core and the mantle due to the very high differences in temperature (the outer core is much hotter than the base of the mantle above it). It is these hot plumes that are thought to be responsible for volcanism at hot spots in the middle of tectonic plates such as the one that created the Hawaiian island chain.
How did Beno Gutenberg discover the boundary between mantle and outer core?
He didnt just discover 'a boundary' between mantle and outer core. He provided the first reasonable accounting of Earths interior (proved the thought that the earth was in layers and not just a homogenous planet). He was also the first to estimate the temperature and physical properties of the earths core, which is why the boundary is called after him. He first discovered the layers through seismic waves from earthquakes, realising they had different magnitudes and intensity because they must have had to go through layers before reaching the surface as well as depending where the epicentre is.
What is the temperature at the boundary between the mantle and the outer core?
90 degrees
Which star's surface temperature is closest to the temperature at the boundary between earth's mantle and core?
The sun!
What is the boundary between the outer core and the inner core?
the boundary between mantel and crust is mohorovisic the boundary between mantel and core is guttenberg
What is the boundary between mantle and core?
The boundary between the mantle and the core is called the core-mantle boundary and also The Gutenberg Discontinuity which marks the upper boundary of the D'' (D Double Prime) layer.
What is the temperature the mantle?
It is 500 to 900 Celsius at the upper boundary and 4000 Celsius at the boundary near the outer core. A2. The values range between 500 deg C at the crust boundary, to over 4 000 deg C at the outer Core boundary.A1. between 100 to 1600 Celsius. The Mantle temperature varies to about 1600-4000 degrees.The average temperature of the mantle is is 5400 ºF (3000ºC).
What the boundary between the core and mantle?
The boundary of mantle and core are called Gutenberg Discontinuity
What is the zone from the base of the asthenosphere to the boundary of the mantle and core?
The mesosphere is the zone from the base of the asthenosphere to the boundary of the earth's mantle and core.
How cool is Jupiter?
It depends on what part. At the core, it's not cool at all; the temperature at the core boundary is estimated at 36,000 K. However, at the "surface" (at the 1 bar pressure level), the average temperature is around 165 K, which is pretty cold: about -110 degrees Celcius.
What is the approximate pressure at the mantle-outer core interface?
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.
What are the properties of the outer core?
The Earth's outer core is composed mainly of liquid iron (85 %) and nickel (5 %) with the rest made up of a number of other elementsThe outer core is 2,260 km thickThe outer core's upper boundary is 2,890 km below the surfaceThe outer core's lower boundary is 5,150 km below the surfaceThe temperature of the outer core varies from 4400 degrees C at it's upper boundary and 6100 degrees C at it's lower boundaryFor more information about the outer core, please see the related question.The depth is 2,250 kilometers. The Thickness is 2,300 kilometers. Composition is made of liquid nickel and iron. Temperature of the outer core is 2,200 Celsius.
What is earths temprture?
From inside out (approximate temperature in Celcius) The inner core is about 7000 degrees C Outer core: 5000 C Lower mantle: 2000 C Upper mantle: 500 C Crust: 0 C
What divides the mantle and the core?
The boundary between the mantle and the outer core is a layer known as D". It is a thermal and chemical boundary where a change in speed of seismic waves has been noted.
