A volcano is considered extinct when it has not erupted for a significant period, typically thousands to millions of years, and shows no signs of any geothermal or magmatic activity. This can occur due to the depletion of magma reservoirs or the cooling and solidification of magma in the Earth's crust, which prevents future eruptions. Extinct volcanoes are often eroded and have lost the features associated with active volcanism.

it's different because a dormant volcano is when a volcano is sleeping but can erupt any time. an extinct volcano is a volcano that's dead. it is very unlikely for an extinct volcano to awaken. the volcano is dead because it has let out all the magma from its chamber or the magma has drifted someplace else or the magma has hardened.
