ACTIVE!
Ones that are sleeping but could erupt again are called DORMaNT!
And ones that are never going to erupt again are called EXTINCT!
Dormant
Volcanoes that no longer erupt is called an extinct volcano. An extinct volcano is defined as a volcano that has not had an eruption in at least 10,000 years, and is not expected to erupt again in a comparable time scale of the future.
Shield volcanoes erupt lava with a low silica content. There are less dissolved gases and a lower viscocity fluid, so less gas is produced and it takes less pressure to erupt.
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
The frequency of volcanic eruptions varies depending on the volcano. Some volcanoes erupt frequently, while others may remain dormant for hundreds or thousands of years. It is difficult to predict exactly how many times a volcano will erupt in the future.
Some do. Most volcanoes will erupt more frequently than that, but some do go 1000 years or more between eruptions.

No. Volcanoes erupt.
About 60 volcanoes erupt each year.
An unlimited amount of volcanoes can erupt at once
Volcanoes can erupt at any time of year.
Volcanoes can erupt in any climate. Climate does not affect a volcano's ability to erupt.
Volcanoes frequently erupt around the Ring of Fire.…
Active volcanoes erupt. Dormant volcanoes are quiet - but may erupt again some day. Extinct volcanoes have "closed up shop" for good, and will never erupt again.
