top will be younger
bottom older
The layer above the 120 million-year-old layer must be younger, and the layer below must be older. So, the layer above the middle layer will be younger than 120 million years, and the layer below the middle layer will be older than 120 million years.
The middle layer of Earth's atmosphere is called the stratosphere. It is located above the troposphere and below the mesosphere. The stratosphere is where the ozone layer is found, which helps to absorb and block harmful ultraviolet radiation from the sun.
OZONE Layer
The middle layer of the atmosphere is called the stratosphere. It is located above the troposphere (the lowest layer) and below the mesosphere (the next layer up). In the stratosphere, the concentration of ozone helps to absorb and block a significant amount of the sun's harmful ultraviolet radiation.
A katydid typically lives in the understory layer of the rainforest, which is the middle layer of vegetation below the canopy but above the forest floor. This layer provides the katydid with shelter, food, and protection from predators.
The layer above the 120 million-year-old layer must be younger, and the layer below must be older. So, the layer above the middle layer will be younger than 120 million years, and the layer below the middle layer will be older than 120 million years.

The components of skin. Epidermis is the top layer. (Epi=above, -dermis=skin). The dermis is the true skin and middle layer. The hypodermis is below the dermis. (hypo=below)

Below the thermosphere are the mesosphere, stratosphere, and troposphere. The mesosphere is the layer of the atmosphere above the stratosphere and below the thermosphere. The stratosphere is above the troposphere and below the mesosphere, and the troposphere is the lowest layer of the Earth's atmosphere.
The middle layer of the sun's atmosphere is called the chromosphere. This region is located above the photosphere and below the corona, and it is characterized by its reddish color during solar eclipses.
The layer of solid rock below the soil is called bedrock. It is composed of consolidated rock that serves as the foundation for the soil layer above it.
horizon
The atmospheric layer below the mesosphere is called the stratosphere. It is located above the troposphere and below the mesosphere, and it contains the ozone layer which absorbs and scatters the sun's ultraviolet radiation.
