Where is earths greatest bulk composition?
mantle
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 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 is the average thickness of the earths upper mantle?
410km
How thick is the earths upper mantle?
about 20 inches
Is probably closest in chemical composition to the upper mantle?
The Earth's upper mantle is composed mainly of silicate minerals rich in magnesium and iron, such as olivine and pyroxene. Basalt is a type of volcanic rock that is commonly found in the upper mantle and has a similar chemical composition to the rocks in the upper mantle.
What do geologist call the earths crust and upper mantle?
The lithosphere.
Crust and earths upper mantle makes up what?
it is the lithosphere
What is the composition of the mantl?
The earths mantle is less dense and it's very hot.
Which forces responsible for earths crust and lithosphere floating on the mantle?
convection currents in the upper mantle
What sphere extends from earths core to earths crust?
The sphere that extends from Earth's core to Earth's crust is known as the mantle. It is a layer of solid rock that lies between the core and the crust, making up the majority of Earth's volume. The mantle is divided into the upper mantle and the lower mantle based on depth and composition.
What layers make up earths lithosphere?
crust and upper mantle
