This storyboard does not have a description.
Sure! Composite volcanoes are formed by layers of tephra,which are rock fragments, and lava, which is molten rock. Some of them erupt tephra fiercely and some gently erupt lava. They have medium size and shape.
Hi! Can you teach me about composite volcanoes? I don't get them at all and I want to be prepared for our test.
What's up? Can you help me understand what a cinder cone volcano is? I have been so busy that I haven't had time to study our notes.
OK! Cinder cone volcanoes are small volcanoes formed by explosive eruptions of tephra. The eruptions are powered by high gas content and are pretty short in duration.
Basaltic lava has a high silica content. The buildup of the layers of lava causes a flat shield volcano. They are the largest volcanoes and occur where plates separate.
Psst! What's a shield volcano? I'm so confused.
Hi! I'm from the school newspaper and we are doing an article on composite volcanoes. Can you tell me a fun fact about them?
Fine, but it will have to be quick. Two famous composite volcanoes are Mt. Fuji in Japan and Mt. Vesuvius in Italy and composite volcanoes are also called stratovolcanoes
I guess. Shield volcanoes are most common in Hawaii, Iceland, and the Galapagos Islands and a famous one is Mauna Loa in Hawaii.
Hey! You! Everyone says you know all about volcanoes, so can you give me a fact about shield volcanoes?
Hi! Everyone thinks you are the volcano expert so can you tell me a fun fact about cinder cone volcanoes?
Cinder cone volcanoes generally have craters at their summit and have steep, angled sides. Now I have to go take MY volcano test!
