The mechanical layer that lies above the spinal cord is the vertebral column, commonly known as the spine. It consists of vertebrae that provide structural support and protect the spinal cord. Additionally, surrounding the spinal cord are protective membranes called meninges, which include the dura mater, arachnoid mater, and pia mater. These structures collectively ensure the integrity and safety of the spinal cord within the vertebral column.
asthenosphere
The mechanical layer that lies below the lithosphere is the asthenosphere. It is a partially molten layer of the Earth's upper mantle that allows the lithospheric plates to move and interact.
The Earth's crust lies above the mantle.
The mechanical layer that lies below the lithosphere is called the asthenosphere. It is a semi-fluid layer of the mantle that allows for the movement of tectonic plates situated above it. The asthenosphere extends from about 100 kilometers to around 410 kilometers beneath the Earth's surface, where it behaves plastically and can flow slowly over geological time. This movement is crucial for processes such as plate tectonics and volcanic activity.
The mechanical layer that lies above the Earth's core is the mantle. The mantle is composed of solid rock that can flow slowly over time, allowing for convection currents that drive plate tectonics. It extends from the outer core to the Earth's crust, making it the thickest layer of the Earth. The upper mantle is also involved in volcanic activity and the formation of mountain ranges.
Mesosphere lies above the core.
The mechanical layer above the core is the mantle. It is a thick layer of rock that sits between the core and the Earth's crust. The mantle is responsible for convection currents that drive plate tectonics and other geological processes.

The tectonic plates are contained within the lithosphere, which is the outermost mechanical layer of the Earth. The lithosphere comprises the crust and the uppermost part of the mantle and is rigid and brittle, allowing the tectonic plates to move and interact at their boundaries. Beneath the lithosphere lies the asthenosphere, a more ductile layer that facilitates the movement of the tectonic plates above it.
mantle
The layer of the Earth that lies above the outer core is the mantle. It is a viscous layer composed of silicate rocks and is divided into the upper mantle and the lower mantle. The mantle is responsible for most of the Earth's internal heat and convection currents that drive plate tectonics.
The asthenosphere lies below the lithosphere.
The layer above the photosphere is called the chromosphere. It is a region of the Sun's atmosphere where temperatures increase with altitude. Above the chromosphere lies the corona, which is the outermost layer of the Sun's atmosphere.
