The surface.
the Crust
It is located in the crust and upper mantle of the Earth.
The crust
The Earth's crust is the outermost layer of the Earth. It is divided into two types: continental crust, which forms the continents, and oceanic crust, which forms the ocean floors.
The Crust.
The mantle is located right under Earth's crust.
The upper mantle is located beneath the Earth's crust, extending from about 30 to 400 kilometers deep. It is part of the Earth's mantle layer, which lies between the crust and the core.
Within the Earth (usually in the upper crust).
The Mohorovičić discontinuity (MOHO) is located between the Earth's crust and mantle, making it directly above the Earth's crust.
The crust of the earth is located right at the top which a thick layer
The center of the Earth is located at a point beneath the Earth's surface, approximately 6,371 kilometers (3,959 miles) below the Earth's crust.
The mantle is that part of the Earth between the crust and the outer core. It's upper boundary is at the base of the crust at a depth below the surface which can vary between 7 and 35 km. It extends all the way to the Earth's outer core at a depth of around 2890 km.the Earths mantle is located between the crust and outer core of the Earth. it is the thickest layer.
