What is the difference between "Evaporation" and "Boiling" (Just say one thing)?

Evaporation - on the surface of a liquid, this liquid changes to a gas (Vapor Pressure < Atmospheric Pressure, does not produce bubbles)

Boiling - when a liquid reaches its boiling point, its phase changes to a gas (Vapor Pressure = Atmospheric Pressure, produces bubbles)
