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.
Shield volcanoes have very fluid lava composed almost entirely of basalt. The lava which arrives at the surface is hot and little changed since the time it was generated. Shield volcanoes are the largest volcanoes on Earth.The basaltic lava can pile up producing huge shields with gentle slopes and convex outlines.hield volcanoes have very fluid lava composed almost entirely of basalt.
