The least viscous layer of the Earth is the outer core. It is composed mainly of molten iron and nickel, which gives it a lower viscosity compared to the solid inner core and the more rigid lithosphere.

The mechanical layer of Earth that is solid rock and moves the least is the lithosphere. It comprises the Earth's crust and the uppermost part of the mantle, forming a rigid outer shell. The lithosphere is divided into tectonic plates that can move, but the individual rocks within this layer are generally stable and do not flow like those in the underlying asthenosphere.
The layer of the Earth that contains molten rock moving in convection currents is the mantle. The mantle lies between the Earth's crust and the outer core and is composed of solid rock that behaves like a viscous fluid over long periods. This movement of molten rock drives the tectonic plates on the Earth's surface, leading to geological activity like earthquakes and volcanic eruptions.
The Earth's outer solid layer is called the crust. It is the thinnest layer of the Earth, making up the continents and ocean floors.

soler system
The only liquid layer of Earth is the outer core, composed of liquid iron and nickel. Deep in the Earth's interior is an iron and nickel core. The center of that core is solid, but there is a layer a thousand miles or more think that is liquid. Above the core is mantle material that is not necessarily considered liquid, because it is so viscous. Earth has an outer solid crust.
The mechanical layer of Earth that is solid rock and moves the least is the lithosphere. It comprises the Earth's crust and the uppermost part of the mantle, forming a rigid outer shell. The lithosphere is divided into tectonic plates that can move, but the individual rocks within this layer are generally stable and do not flow like those in the underlying asthenosphere.
The physical layer of Earth located beneath the lithosphere is the asthenosphere. It is a semi-fluid layer of the upper mantle that allows for the movement of tectonic plates. This layer is composed of solid rock that behaves like a viscous fluid over geologic time scales.

The rocky upper layer of the solid Earth is called the crust.
The mantle is a semi-solid layer of Earth located below the crust and above the core. It behaves like a solid over short time scales but can flow like a slow, viscous fluid over long time scales, causing tectonic plate movement.
The core is the chemical layer of the Earth with a liquid layer (the outer core), and a solid layer (the inner core).
The Earth's outer solid layer is called the crust. It is the thinnest layer of the Earth, making up the continents and ocean floors.
