The mantle
Magma is the semi-molten rock layer on which the crust floats.
35 - 60 Kms would be the uppermost mantle, which along with the crust forms the hard, brittle lithosphere. The Mantle is a semi-molten layer.
Continents and oceans are located on the Earth's outermost layer, known as the crust. Beneath the crust is the mantle, which consists of solid rock that can flow under high pressure. The molten rock, or magma, is found in the Earth's innermost layer, the outer core and the inner core.
The thin crust of the planet floats on the molten core.
The Mantle
Magma is fluid molten rock that exists under the Earth's crust.
The layer of the Earth which forms the tectonic plates is composed of the crust and uppermost mantle and is called the lithosphere.

The layer that is thinnest under the oceans is the crust. While it is thinnest in those underwater regions, it is the thickest in the regions where mountains are.
The uppermost layer of the Earth is called the crust. It is divided into two types: continental crust, which makes up the landmasses, and oceanic crust, which forms the ocean floors. The crust is thinnest under the oceans and thickest under mountain ranges.
The outer core is the only layer with molten in it.
