The outside layer of a clam shell is the periostricum. The middle layer is the prismatic layer. The inside layer is the nacreous layer.
Yes, a clam shell is made up of cells, specifically mineralized cells known as calcifying cells, which produce the shell's hard outer layer. The shell itself is primarily composed of calcium carbonate, formed through biological processes. While the shell is not living tissue, it is produced by the living organism (the clam) and is influenced by the clam's cellular activities.
The outer layer is made of amphipathic phospholipids, free cholesterol, and apolipoproteins.
The outer layer of the skin, called the epidermis, is mostly made up of dead skin cells called keratinocytes. However, the deepest layer of the epidermis contains living cells that are responsible for producing new skin cells.

The layer of the earth made of liquid metal is called the Outer Core, I will attach a link below which shows a diagram of the Earth's structure.
The earth's outer core consists of a liquid layer of lave made up of nickel and iron. The thickness of this layer is 1,408 miles. The outer core is located below the mantle.

Since we have an atmosphere that is made up of 4 layers. One the most outer layer the thermosphere. Then the 3 most outer layer is the mesosphere. Next is the Stratosphere the third most outer layer. Last the closest layer the Troposphere which is where we all live.
