What are the 3 main things that come out of a volcano?

Answer 1

1. Gases- Volcanoes eject different types of gases, the main ones being water vapor, carbon dioxide, nitrogen, sulfur, and other less abundant gases.
2. Lava flows- are produced by the magma which reaches the earth's surface. This lava then begins to flow down the side of the mountain. One type of a lava flow is a Pahoehoe flow which has a smooth surface with wrinkles in it, which create a silky-apearance.
3. Pyroclastic material is characterized by the rapid expansion of lava, rocks, and glass fragments which blow out in many pieces varying greatly in size. Many times bombs and blocks are ejected from the volcano, but normally they fall close to the cone, AND Nuee-ardente is an extremely fast-moving body of lava and gas. The lava actually floats on top of the gas which causes little friction, and thus the two travel down the mountain at speeds well over 60 miles-per-hour. The nuee-ardente is most commonly associated with the strato-volcano, and can be very devastating due to the rapid movement.
