Difference between thermal dissociation and thermal decomposition

Thermal Decomposition...**":;
..
Thermal decomposition is a form of chemical decomposition caused by heat. It is also known as thermolysis. The temperature at which the decomposition initiates is known as decomposition temperature. It is a multi-step process.
Decomposition involves the breakdown of chemical bonds. In order to break a chemical bond, energy should be given from outside. Therefore, a thermal decomposition is usually an endothermic reaction.The most common example for substances that undergo thermal decomposition is transition metal carbonates.
Example of Thermal Decomposition..**";:
Calcium carbonate (CaCO3) decomposes into calcium oxide (CaO) and carbon dioxide (CO2) when heat is provided.
CaCO3(s)→CaO(s) + CO2(g)

THERMAL DISSOCIATION..**";:'
Thermal dissociation is the ionization of a substance using heat. The substance is separated into cationic and anionic counterparts. It is a single step process that includes the split of a substance into two parts. This reaction is usually a reversible process and one chemical bond is broken.
The original compound can be obtained by cooling the reaction mixture since the process is reversible.
Example...
CH3Br → CH3++ Br–
CH3-CH3 →CH3+ + CH3–
