What are the characteristics of acid lava?

Acid lava, often referred to as rhyolitic lava, is characterized by its high silica content, typically exceeding 60%. This composition results in a thick, viscous texture that prevents gases from escaping easily, leading to explosive eruptions. Acid lava generally forms steep-sided volcanic structures, like dome volcanoes, due to its tendency to solidify quickly upon eruption. Its cooler temperatures and slower flow rates contrast with the more fluid basaltic lavas.
