Below are two very simple profiles of volcanoes (A - a shield volcano, B-a composite volcano), Use these diagrams to heip answer the following questions. A) shield volcano 8) composite volcano Not to scale Which volcano is formed from runny lava and which is formed from viscous lava? Composite Shieid voicano 1 poime Which volcano is formed from mafic lava? Both Shield Neither Composite I point Phyolite is an igneous rock that is light in color. Basalt is a very dark colored igneous rock. Which volcano is composed of rhyolite and which is composed of basalt? If gasses cannot easily escape from a volcano, the eruptions from this volcano will be explosive. Lava that is runnier allows for gasses to bubble out so there is no eiplasion. Gasses cannot bubbie out of viscous lava. Which type of lava will easily let gasses escape? both mafic felsic: 5 point. Which volcano would erupt explosively? Sheeld Composite.
