A volcano is an opening in the Earth's surface through which heated materials (lava, ash, or gas) escape from below the ground.
The stereotypical volcano forms a cone-shaped mountain of solidified magma and ash. But the basic form is a circular crater or caldera, containing a pool from which superheated materials are expelled by pressure from the source below.
The flank of a volcano is the ridge at the top opening of the volcano that was created by lava deposits during eruption,æ Volcano flanks are very unstable and can contain vertical fractures which make them dangerous to study.
The crater of a volcano is the bowl-shaped depression that forms at the summit or vent of the volcano after an eruption. It is typically created by the explosive expulsion of volcanic material, which can include ash, gas, and lava, resulting in a hollowed-out area. The size and shape of the crater can vary significantly depending on the volcano's eruption history and type. In some cases, craters can evolve into larger structures called calderas if the collapse occurs after a massive eruption.
No. It is a complex volcano, with multiple features resulting from varying types of eruption.
The arenal volcano is a cindercone volcano not a composite.
The opposite of an active volcano is an extinct volcano, which is a volcano that has not erupted in a long time and is not expected to erupt again.
That depends on how you define "biggest". If it is by area, then it is and unanswerable question. If it is by eruption magnitude, then it is probably Hekla. the largest volcano is seemingly Askja.

No, not by any definition. If you define the "youngest volcano" by "most recently erupted", then that honor goes to Kilauea, which has been erupting non-stop since 1983. Mount St. Helens last "erupted" in early 2008 when steam escaped from a fracture in the lava dome.
A Strato volcano or a composite volcano.
No. It is a composite volcano.
Cleveland volcano is in Alaska & is a Stratovolcano (composite volcano)
No. It is a complex volcano, with multiple features resulting from varying types of eruption.
The Taal volcano is the smallest volcano in the Philippines. Not only is it the smallest volcano in the Philippines, it is the smallest volcano in the world.
A dormant volcano is a volcano which has had an eruption but it was a long time ago. It is a volcano which shows no sign of activity or a future eruption. Basically, a dormant volcano is a volcano which is asleep.
A Sub Glacial Volcano
