What is the layer 100 km below the earths surface?
The mantle =)
The thickness of the earths mantle?
The Earth's mantle is about 2,890 km (or 1,800 mi) thick.
How thick is the earths mantle?
The thickness of the Earth's mantle is about 2900 km and it's upper boundary is about 100km deep. There is a really cool cutaway drawing available by using the Wikipedia link.
Is the asthenosphere located between the mantle and outer core?
The asthenosphere is part of the upper mantle. It's upper boundary is approximately 100 km deep and it's base is around 700 km deep.
What is the earths under crust surrounded by?
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
How far is the Earth's mantle from the crust?
it may be 2900 km The mantle is about 1,800 miles deep, and depending on where on the earth, it may be between 10km (where there is a thinner lithosphere) to 50+ km!
Which layer makes up the majority of earths interior?
The mantle is the largest layer in the Earth's interior.
What is the size of the earths crust?
The Earths crust is approximately 650 km deep.
Hot deep is the earths mantle?
Earth's mantle is a rocky shell about 2,890 km (1,800 mi) thick that constitutes about 84 percent of Earth's volume. Two main zones are distinguished in the upper mantle: the inner asthenosphere composed of flowing rock in the state of plasticity, about 200 km thick, and the lowermost part of the lithosphere, composed of rigid rock, about 50 to 120 km thick. A thin crust, the upper part of the lithosphere, surrounds the mantle and is about 5 to 75 km thick. The mantle is divided into sections which are based upon results from seismology. These layers (and their depths) are the following: the upper mantle (starting at the Moho, or base of the crust around 7 to 35 km, downward to 410 km), the transition zone (410-660 km), the lower mantle (660-2891 km), and in the bottom of the latter region there is the anomalous D" layer with a variable thickness (on average ~200 km thick)
How thick are the earths layers in km?
crust: average of 32 km thick mantle: 2900 km thick outer core: 2200 km thick inner core 1250 km thick
How many kilometre outer mantle to inner mantle?
Scientists predict the mantle is about 2,900 km (1,800 mi) thick.
What is the thickness of earth's layers?
the crust is the thickness of earths layers
