The average composition of rocks composing a large composite volcano is similar to which magma?

Question

Quizplus · Accepted Answer

Large composite volcanoes are typically formed from a mixture of lava flows and pyroclastic deposits from multiple eruptions. The average composition of rocks composing these volcanoes is intermediate to felsic, meaning they contain significant amounts of silica. This points towards both andesitic and felsic magmas as potential answers. However, it is difficult to definitively choose just one magma composition as compositions can vary greatly depending on the specific volcano. Therefore, C) and/or D) are the best choices.
