how is exosphere layer heated
Ozone layer is a layer having only one layer of gas. That layer of gas is ozone layer.
There are seven type of OSI reference model:-Layer 7: The application layer Layer 6: The presentation layer Layer 5: The session layer Layer 4: The transport layer Layer 3: The network layerLayer 2: The data-link layer Layer 1: The physical layer
physical layer Data Link Layer Network Layer Transport layer session layer Presentation layer Application layer
A layer in atmosphere is at risk. The layer is ozone layer.
Layer 1 - the physical layer
Layer > New > Background from Layer.
transport layer
The layer below the earth's outer layer is mesosphere. It is the 3rd layer.
Session Layer - layer 5Transport Layer - layer 4
The stratosphere is a layer in atmosphere. It contains another layer within it. The name of that layer is ozone layer.
Application Layer
There are 7 layers in the OSI model which are from top to bottom: application layer / presentation layer / session layer / transportation layer / network layer / data link layer / physical layer
