What is the range of pressure within the stiffer mantle?
The pressure within the stiffer mantle ranges from about 14 GPa (gigapascals) at the upper boundary to over 136 GPa at the core-mantle boundary. This high pressure contributes to the solid-state behavior of the mantle material despite its high temperature.
The type of plate boundary where plates move apart resulting in upwelling of material from the mantle to create new sea-floor is known as what plate boundary?
Mid-Atlantic Trench
Topographic highs in the crust have deep what that extend into the mantle and provide buoyant support?
Topographic highs in the crust have deep roots that extend into the mantle and provide buoyant support through isostasy. These roots are a result of the difference in density between the crust and underlying mantle, allowing for uplifted regions to be supported by the denser mantle material beneath.
What is the boundary between mantle and core?
The boundary between the mantle and the core is called the core-mantle boundary and also The Gutenberg Discontinuity which marks the upper boundary of the D'' (D Double Prime) layer.
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.
What the boundary between the core and mantle?
The boundary of mantle and core are called Gutenberg Discontinuity

Which area indicates a dramatic decrease and material density inside the earth?
The transition from the outer core to the lower mantle, known as the core-mantle boundary, is a region where there is a dramatic decrease in material density inside the Earth. This boundary is characterized by a significant change in the physical properties of the materials, such as a decrease in density and an increase in seismic wave velocity.
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 is the zone from the base of the asthenosphere to the boundary of the mantle and core?
The zone you are referring to is the mesosphere, which lies between the base of the asthenosphere and the boundary separating the mantle from the core. It is characterized by high pressure and temperature conditions, as well as the gradual increase in density from the bottom of the mantle to the core-mantle boundary.
What type of boundary is yellowstone?
Yellowstone is not on a plate boundary, but is a 'hotspot' where magma seeps from the mantle to the surface, or near the surface. The case is the same for Hawaii.
What are continent-sized columns of superheated mantle material originating at the core-mantle boundary and rising upward due to a change in density?
The phenomenon described is known as mantle plumes. They are thought to be responsible for volcanic hotspots such as Hawaii and Iceland due to the upwelling material creating magma and forming volcanoes as it reaches the Earth's surface.
What is the change in the physical properties of Earth's interior at the mantle-core boundary that makes P waves go through the boundary?
At the mantle-core boundary, there is a change in density and composition of the material. The increase in density and the solid state of the core allow P waves to travel through, with some refraction due to the change in velocity.
