Caldera Volcano Questions

How many active volcanoes are there on our planet?

‐1500 active volcanoes

How do volcanoes decrease global temperatures?

‐Volcanoes decrease global temperature because sulfur dioxide is thrust into the air and it hinders the sunlight.

How can some volcanoes increase global temperatures?

‐They release a lot of carbon dioxide that play a greenhouse effect on the earths atmosphere.
