What is the surface that separates the core from mantle?
Transistion zone.
Which layer of the Earth separates the crust and mantle?
The Core Mantle boundary - also known as the Guttenberg discontinuity separates the earth's mantle from its core. It is divided into two layers, the inner core and the outer core. The inner core, the center of earth, is solid and about 780 miles (1,250 km) thick. The outer core is so hot that the metal is always molten, but the inner core pressures are so great that it cannot melt, even though temperatures there reach 6700ºF (3700ºC). The outer core is about 1370 miles (2,200 km) thick. Because the earth rotates, the outer core spins around the inner core and that causes the earth's magnetism.
What is the thick rocky layer around earths core?
The core of the earth is surrounded by the mantle.The earth's core is called the inner core. Just outside that is the outer core, and it is liquid. Outside the liquid outer core is the mantle.
What are the layers of the earth from thinnest to thickest?
From thick to thin: mantle, outer core, inner core, crust.
What is under the mantle?
Below the mantle is the core.
What is the surface that separates the core from mantle?
Transistion zone.
What is the mantle of?
It is composed of very hot rock that is "plastic" (slowly moving and deforming). It is not as liquid as the outer core, or the magma that separates the crust from the mantle.
What is named after the German geologist that discovered the thing that separates the earth's mantle from the outer core?
the Gutenberg discontinuity
The shadow zone separates P waves that have reached the surface through the mantle from P waves that have reached the surface after passing through both the mantle and the core?
true.

The Gutenberg Discontinuity is found beneath this layer?
The Gutenberg Discontinuity is found above the earth layer called the outer core. This boundary line, which separates the outer core from the lower mantle, is approximately 1798 miles below the Earth's surface.
Match the layers with its characteristic?
Crust- ranged from 6km to70km thick . mantle- convection here leads to earthquakes. Core -has a liquid and soild layer Moho barrier- separates the crust and mantle. APEX
What is the thick rocky layer around earths core?
The core of the earth is surrounded by the mantle.The earth's core is called the inner core. Just outside that is the outer core, and it is liquid. Outside the liquid outer core is the mantle.
What are the layers of the earth from thinnest to thickest?
From thick to thin: mantle, outer core, inner core, crust.
How are the mantle and core alike?
the core is corey and the mantle is mantely
How far is core from mantle?
3160 miles-mantle to inner core.
What are the zone between core and crust?
The chemical layer of the Earth known as the mantle lies between the crust and the core.
