The mantle is composed of hot mafic and ultramafic silicate rock under great enough pressure to prevent it from melting, despite experiencing temperatures which at shallower depths would cause it to liquify.
The core is compositionally different from the mantle in that it is composed primarily of iron, with nickel, and minor amounts of other elements. The outer core is considered a liquid metallic alloy, and the inner core is considered a solid alloy. The phase difference is due to the increased pressure existing in the inner core which prevents it from behaving as a liquid despite temperatures that are probably equal to those at the surface of the Sun.
The above differences are mainly compositional; however, there are differences in physical properties such as density and temperature (both of which increase with depth), strength and deformation behaviour, as well as things like layer thickness (the mantle is thicker), and depth from surface (the core is deeper).
What else can I help you with?
What divides the mantle and the core?
The boundary separating the Earth's mantle and core is known as the core-mantle boundary. This boundary is characterized by a sharp decrease in seismic wave velocities, indicating a difference in composition and properties between the outer core and the lower mantle.
What do you called the boundary between the mantle in the core?
The boundary between the mantle and core is called the core-mantle boundary. This region is marked by a significant change in density and composition, representing the transition from the solid mantle to the liquid outer core of the Earth.
Give two differences between the mantle and the core?
The mantle is a layer of the Earth that lies between the core and the crust, while the core is the innermost layer made up of the outer liquid core and the solid inner core. Another difference is that the mantle is mainly composed of solid rock materials, while the core is primarily made up of metallic elements such as iron and nickel.
What is the difference between the mantle and outer core of the Earth?
There are differences in chemistry (the mantle is mainly ultramafic rock--the outer core is metallic), in phase (the mantle is predominately solid--the outer core is liquid), in depth (the outer core is closer to the center of the Earth), and in density (the outer core is more dense).
What is the difference between Mohorovicic discontinuity and Gutenberg discontinuity?
Mohorovicic discontinuity is located between the upper mantle and the crust, while the Gutenberg discontinuityis located between the lower mantle and the outer core.

What the boundary between the core and mantle?
The boundary of mantle and core are called Gutenberg Discontinuity

What is middle layer of earth called?
Between the thin rocky crust and inner core, in order from upper to lower, are the upper mantle, mantle, and outer core.
Which is thicker the mantle or the two core layers cobmine?
The two core layers (outer and inner core) are denser and thicker than the mantle. The mantle is the layer between the core and the crust of the Earth, and it is thicker than the core layers.
What is the difference between Mohorovicic discontinuity and Gutenberg discontinuity?
Mohorovicic discontinuity is located between the upper mantle and the crust, while the Gutenberg discontinuityis located between the lower mantle and the outer core.
What is the difference between the core and the lithosphere?
The core is the innermost layer of the Earth, composed mostly of iron and nickel. It is divided into the outer liquid core and inner solid core. The lithosphere is the rigid outer layer of the Earth, consisting of the crust and upper part of the mantle.
Name the layer between the inner core and the mantle?
The outer core.
What layer is between the crust and the core?
The mantle.
What is between the crust and the core of the earth?
The mantle.
