Answer to Question 1

Most cinder cones are produced by a single, short-lived eruptive event. One study found that half of all cinder cones examined were constructed in less than one month and that 95 percent formed in less than one year.

Answer to Question 2

Composite volcanoes are mostly formed from thick, viscous, andesitic composition lava, whereas shield volcanoes are formed from runny, less viscous, basaltic composition lava.
