Do continents drift slowly on earths upper mantle or earths core?
Continents drift on top of the upper mantle. The core is much further down.
How thick is the earths upper mantle?
about 20 inches
What is earths upper mantle composition?
hard rock
How far down is the earths upper mantle?
The upper mantle of Earth begins just beneath the crust, which ranges in thickness from about 5-70 km (3-44 miles) depending on the location. The upper mantle extends to a depth of about 670 km (416 miles) beneath the Earth's surface, marking the boundary with the lower mantle.
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.
What is is the thickness of the upper mantle?
In oceanic areas the upper mantle is usually 5-200km thick and on continental areas it is 75-300km deep.
What do geologist call the earths crust and upper mantle?
The lithosphere.
Crust and earths upper mantle makes up what?
it is the lithosphere
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle
What is crust and upper mantle of the EARTH?
The upper mantle is in between the lower mantle and the earths crust Crust- the outer most solid shell of the earth. The Uppermost mantle and the earth's crust form the lithosphere.
What layers make up earths lithosphere?
crust and upper mantle
What is the upper part of the earths mantle?
The asthenosphere is the upper part of Earth's mantle. It is partially molten (plastic rheology) and mechanically detached from the lithosphere, which is mostly the Earth's crust (but also a little bit of upper mantle). The density of the upper mantle is your mom! (yo mamma!)
