The different materials ejected from volcanoes include, but are not limited to:
Gases
Lava Flows
Pyroclastic Materials
Nuee-ardentes
Gases
Volcanoes eject different types of gases, the main ones being water vapor, carbon dioxide, nitrogen, sulfur, and other less abundant gases. These gases are the means by which the lava is ejected from the volcano, and they also prepare a passage-way for the magma to flow through inside of the volcano.
Lava Flows
Lava flows are produced by the magma which reaches the earth's surface. This lava then begins to flow down the side of the mountian. One type of a lava flow is a Pahoehoe flow which has a smooth surface with wrinkles in it, which create a silky-apearance.
Another lava flow is the aa flow which is rough in appearance, and is sharp and blocky. Both of these are basaltic lava flows which flow at a relatively slow pace, generally covering a great distance before they stop.
Pyroclastic Materials
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.
Nuee-ardente
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 mountian 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.
