What else can I help you with?
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.
What is the average thickness of the earths upper mantle?
410km
What is earths upper mantle composition?
hard rock
How thick is the earths upper mantle?
about 20 inches
What are facts about earths upper mantle?
Temperature is about 2000 to 3000 degrees celsius maybe less.The mantle is hot but not the hottest layer.It is is the second layer of the Earth. The mantle is the thickest layer of the earth, it is the layer of the earth beneath the crust.Upper mantle and Lower mantle are the two parts of the mantle, The lower mantle is deeper and denser than the upper mantle .
How many layers in earths mantle?
The Earth's mantle has two main layers: the upper mantle and the lower mantle. These layers are distinguished by differences in their composition, temperature, and behavior. The upper mantle extends from the crust to a depth of about 410 miles (660 kilometers), while the lower mantle extends from about 410 miles (660 kilometers) to approximately 1,800 miles (2,900 kilometers) below the Earth's surface.
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 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!)
What are three differences between the upper and lower mantle?
Temperature: The upper mantle is cooler than the lower mantle. Composition: The upper mantle is more silicate-rich and less dense compared to the lower mantle. Physical properties: The upper mantle is more rigid and brittle, while the lower mantle is more ductile and capable of flow.
