Hawaii and Yellowstone volcanoes are hotspots. The erupted Hawaii lavas are basalt but the erupted Yellowstone lavas are rhyolites. Why are the two lavas different?

While both hotspots have basalt supplies at the base of the crust, the low-density basalt magma rises quickly through Hawaii's high-density, thin, oceanic crust but the low-density basalt magma rises slowly through the low-density, thick, continental crust of Yellowstone, thus it cools slowly and fractionates beneath Yellowstone to form rhyolites at eruption.
