Is it known when they last erupted. Shield, Cinder cone and Composite. Thanks in advance for any help you provide me. I'll be using this imformation in my science project. To give an answer to how many active and inactive volcanoes there are requires an understanding of what is meant by active.
Many people only think a volcano is active when red lava or ash are erupting.
I can tell that you are interested in the volcanoes of the Middle East. Ararat is a composite or stratovolcano, and according to the Bible, is the place where Noah's arc came to rest after the great flood. You can see a picture of Ararat taken by astronauts on the Space Shuttle by clicking here. I do not believe Mt. Sinai is a volcano, because there are no volcanoes on the Sinai Peninsula or in other parts of Egypt. But Mt. Sinai could be made of very old volcanic rocks.
