I wanted to know how I can make this foggy effect on the background just like in the image below, that the far parts are hidden by the fog.
Thank you.

In the example below, I used "multiply", as this gives the best generalized effect, whereas, "add" will make the fog "fill in" the caverns as the camera scrolls out. Have a try with both if you like.
This is the scene in solid mode:
As you can see, all I did was surround the scene with a cube, remove the surface color from the cube, and connect the Volume Scatter with a low density (governed by the Math nodes)
You can achieve this effect using a Mist Pass in the compositor. Search on this site for "Mist Pass" and you should find many examples.
