Some key points are
1) Evaporation takes internal energy while for boiling we have to provide external energy or we have to reduce the pressure.
2) As Evaporation takes internal energy therefore evaporation results in cooling while this is not observed in boiling.
3) Evaporation occurs below saturated temperature while Boiling occurs at and above saturated temperature.
4) Evaporation occurs at liquid-vapor interface while Boiling occurs at solid liquid interface.
5) Vapor bubbles are formed in Boiling while in Evaporation there are no bubble formation and no bubble motion.
6) There are different regimes of boiling (like nucleate boiling, transition boiling, film boiling etc.) while these regimes are not present in Evaporation.
7) Rate of Evaporation is much slower than the Boiling.
8) Example of Evaporation are
Water in a lake at 20°C, evaporates to air at 20°C and 60 percent relative humidity since the saturation pressure of water at 20°C is 2.34 kPa, and the vapor pressure of air at 20°C and 60 percent relative humidity is 1.4 kPa. Other examples of evaporation are the drying of clothes, fruits, and vegetables; the evaporation of sweat to cool the human body; and the rejection of waste heat in wet cooling towers.
i am hoping that the above comparison will give you the clear picture about the evaporation and boiling.

What is the Difference between evaporation condensation precipitation?
evaporation is a method to condensing
The difference between precipitation and evaporation?
i think the answer is that evaporation is wen the water of liquid dries up
What is the difference in between conensation and evaporation?
evaporation floats up in the air and condensation does not i don't know
What is the differentiate distillation from evaporation?
The difference between evaporation and distillation is evaporation is a function of nature and distillation is a process whether it be to separate a liquid or purify it
What is the difference between the processes evaporation and boiling in pure water?
Evaporation is completely natural. Boiling isn't. Hopefully this helps.
What is the main difference between condensation and evaporation?
evaporation is the process of water going from a liquid to a gas. condensation is the formation of clouds
What is the difference between crystallization and evaporation?
Crystallization -may be defined as a process which separates a pure solid in the from of its crystals from a solution. Evaporation - Process of separating any substance from its solution by removing water is called evaporation.
What is difference between volatility and evaporation in chemistry?
After my opinion a strict separation is not possible.
What is the difference between evaporation and transportation?
evaporation is when water goes to the sky and comes back down again and transportation is when something travels.
What is the different between vaporization evaporation and boiling?
The difference between them is that boiling is when you heat a liguid and it turns into a gas, vaporization is when a liquid changes into a gas and evaporation occurs at the surface of a liquid beneath its boiling point.
Are variables in evaporation?
For evaporation from a pure water surface, the rate of evaporation is proportional to the difference in vapor pressure between that of the water surface and that of the bulk air over it. The vapor pressure of water in turn depends on its temperature.
Difference between evaporation and vaporization?
Vaporization is the conversion of a solid or liquid into a gaseous state. Evaporation is a type of vaporization, where liquid is converted to a gaseous state where the environment is not saturated.
