The core, the matle, and the crust.
The concentric layers are the sclera,conjunctiva,and the cornea
The Earth's mantle is below the crust. The layers of the Earth form concentric spheres. Below the mantle is the core.
Concentric lamellae.
there were many layers
An onion is a common object with a layered structure. It has concentric layers of skin surrounding the inner flesh of the vegetable.
The layers of calcified matrix in bone tissue are called lamellae. These lamellae are arranged in concentric circles around central canals called Haversian canals, forming the structure known as an osteon or Haversian system.

Concentric lamellae
Sclera, choroid, and the retina.
The layers of a coffee fruit, or cherry, can be compared to the Earth's structure in that both consist of distinct, concentric layers. In a coffee cherry, the outer skin (exocarp) is akin to the Earth's crust, while the fleshy pulp (mesocarp) resembles the mantle, and the seed (endocarp) can be likened to the Earth's core. Each layer plays a crucial role in protecting and nurturing the inner seed, similar to how Earth's layers support and sustain life on its surface. Both structures exhibit complexity and interdependence among their layers.
Compact bone tissue is arranged in concentric layers called lamellae around a central canal that contains blood vessels and nerves. These layers give compact bone its strength and resilience, helping to support the body and protect vital organs.
The nearly spherical ice pellets with concentric layers formed by the freezing of water layers are known as ice pellets or graupel. Graupel forms when supercooled water droplets freeze on snowflakes or ice crystals, creating a layered structure.
