Layer D is called the Mantle. It is the second layer of the Earth, located beneath the crust and above the core. The mantle is composed of solid rock that is capable of flowing over long periods of time.
The d layer of the Earth is named based on the depth at which it is found, between 1,800 and 2,900 kilometers below the surface. It is part of the mantle and is composed of dense, ultramafic rock. The designation "d" likely stands for "deep."
The three primary layers of the Earth's ionosphere are the D layer, which is the lowest layer closest to the surface, the E layer, which is the middle layer, and the F layer, which is the highest layer. Each layer has unique characteristics and plays a role in the reflection and absorption of radio waves in the atmosphere.
To compare the ages of layers b and d, one would typically look at their relative positions in a geological context. If layer b is above layer d, it is generally considered to be younger due to the principle of superposition. Conversely, if layer b is below layer d, then layer b is older. Radiometric dating or other dating methods could provide precise age estimates for both layers if needed.
The deepest layer of the endometrium is called the basalis layer. It is responsible for regenerating the functional layer of the endometrium each menstrual cycle.
In 1942 the geophysicist Keith Bullen published a paper describing the earth's internal layering in which he used letters to designate various layers from the surface to the core. In this scheme, the earth's lower mantle was known as the D layer.

The mesosphere. The D'' (D Double Prime) layer is the deepest part of the mantle.

datalink layer
The layer of atmosphere is stratosphere. It is the second layer to troposphere.
The stratosphere is a layer in atmosphere. It contains another layer within it. The name of that layer is ozone layer.
