Explanation:

Volcanoes can be classified in different ways. They can be classified based on shape, structure, lava type, activity, and explosiveness. However, all these characteristics are interrelated in a way, where one can determine the other, or one can be the effect of the other. For example, the lava type is the cause of the shape of a volcano.

There are four types of volcanoes:

Stratovolcano/composite volcano - tall (around 8,000 ft) , steep, slow moving lava, explosive.

Shield volcano - broad and not too steep, tall (can grow the tallest actually, can grow up to 30,000 ft), lava is thin.  

Cinder cone - symmetrical cone, bowl-shaped crater, steep by the crater, lava comes out in blobs and rain on the of the crater in short distances which makes it bowl-shaped. Not too tall compared to the other two volcanoes, just up to 3,000 ft)

Lava domes - short (around 330 ft), they form from very viscous lava that move very slowly, not too steep (slope is around 30 degrees).
