We all know that we have different personality traits that make us unique human beings. Some of us seem to prefer order and predictability. We feel comfortable when we work on a schedule. A good day is when we can check everything off our to do list. While others of us are more spontaneous and become bored when things are too predictable.
Venus has over 150 large shield volcanoes. These shields are mostly between 100 and 600 km across, with heights between about 0.3 and 5.0 km. The largest shields, however, are over 700 km in diameter and up to 5.5 km in height.
Composite volcanoes (also called stratovolcanoes) are much more explosive than shield volcanoes, the other important type of volcano.The large and generally cone-shaped volcanoes form along plate boundaries called subduction zones where one of the Earth's plates moves below another.omposite volcano magma contains more silica, SiO 2, than that of a shield volcano and is therefore stickier (more viscous).
