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).
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.
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.
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.
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).
Mohorovicic discontinuity is located between the upper mantle and the crust, while the Gutenberg discontinuityis located between the lower mantle and the outer core.

Between the thin rocky crust and inner core, in order from upper to lower, are the upper mantle, mantle, and outer core.
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.
Mohorovicic discontinuity is located between the upper mantle and the crust, while the Gutenberg discontinuityis located between the lower mantle and the outer core.
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.
