What else can I help you with?
What is the name of the mechanical that is composed of the crust and the top portion of the mantle?
The lithosphere.
What is the crust and brittle upper mantle called?
Earth's crust and brittle upper mantle is called the lithosphere.
The lithosphere is composed of which parts of the Earth?
The lithosphere is composed of the Earth's crust and the upper part of the mantle. It encompasses the solid outer layer of the Earth, which includes the rigid outermost layer of the crust as well as the uppermost portion of the mantle.
Earth is composed what of main three layers?
Crust, mantle, and core
What earth layer contains the crust?
The Earth's crust is part of the outermost layer of the Earth, which is composed of the crust and the uppermost portion of the mantle. This layer is known as the lithosphere, which includes both the continental crust and the oceanic crust. Beneath the lithosphere lies the asthenosphere, which is a more ductile part of the upper mantle.
Why does Earth's crust sit on top of the mantle?
The crust lies on top of the mantle because it is composed of less dense materials than the mantle is. The crust is essentially floating on the mantle.
What is portion of earth between the crust and the core?
The mantle.
What layer of earth is made up of crust and mantle?
The lithosphere is composed of the crust and hard uppermost attached mantle.
What kind of rock are the tectonic plates composed of?
Tectonic plates are composed of primarily of lithosphere, which is a combination of crust and upper mantle rock. The crust portion is mainly made up of igneous and metamorphic rocks, while the upper mantle portion consists of peridotite, a type of ultramafic rock.
Plates are composed of the?
crust and part of the upper mantle
What contains the lower mantle?
The mantle extends to the core-mantle interface at approximately 2900 km depth. Thus, the mantle contains the lower portion of the lithosphere, the asthenosphere, and the mesosphere. The crust is made of the upper portion of the lithosphere.
Is the lower portion of the crust and the upper portion of the mantle called the core?
No, the lower portion of the crust and the upper portion of the mantle together are not called the core. The core is a separate layer found beneath the mantle, and it is divided into the outer core and inner core based on composition and properties.
