While debugging a uC code - I noticed that all variables declared outside of the "main" function are stored in the RAM.

Why does this happen?
Is this always true?
 

Yes, variables declared outside main function are global variables and they are created in RAM and always exist.

Aren't all the variables supposed to be stored in RAM? :?:

They are global variables and stored in memory stack (RAM).
Local (auto) variables, usualy are stored in stack (RAM).
There are some exceptions for mC that do not implement stack control, but always variables are stored in RAM. Only constant values can be stored in ROM.
