When a secondary vent opens on a volcano the name can depend based on the type of eruption as well as the type of volcano. If a Shield Volcano has a secondary vent eruption it is called a rift eruption. This is demonstrated in the current eruption on Kileaua volcano in Hawaii. In a stratovolcano a secondary vent can either be a rift vent, or a cinder cone. This depends on the nature of the eruption. If it is a moderate explosive eruption with minor lava effusion than it would develope into a cinder cone, while if it is a constant lava spatter it would be deemed a rift zone eruption. There are several other minor terms of events, however they are extremely rare and are associated with both of these types of eruptions.
It is called a volcanic error
A lava flow is where lava flows down the side of a volcano.
lava
Generally a volcano will eject lava from the top of the familiar conical shape but many have smaller vents on the side which appear via cracks or fissures called 'dykes' which blow lava out sideways and form what are called 'parasitic cones' on the side of the main conical form of the volcano.
The MAIN vent of the volcano is where all the lava comes out. The side vent is out the side and also is where some lava comes out.
lava layers is layers in side a volcano the color is ushely brown and black
lava!
once it leaves the volcano it cools down and solidifies on the side of the volcano it then gets compressed and forms layers on the side of the volcano.
The lava flowed down the volcano and gas got in the side vents
according to my science class, its igneous rock. igneous rock is formed when magma/lava cools. if it cools slowly, it is conglomerate (coarse-grained or heavily grained..chunky.) if it cools fastly, it is fine grained (smooth.) i hope this helps!
Actually, the molten rock is called lava. The magma from the magma chamber shoots up the main vent and when the magma reaches the vent, it will turn into lava. After that.. I don't have any idea..
Lava.
