The Viscosity Divide: Exploring Why Felsic Lava Flows Differently Than Mafic Lava During Volcanic Eruptions
Safety & HazardsVolcanic eruptions are among the most powerful natural events on Earth. They can cause widespread destruction and have a significant impact on global climate and ecosystems. The type of lava that erupts from a volcano is determined by its chemical composition, which can be felsic or mafic. Felsic lava is typically associated with explosive eruptions,

Caverns in the Mantle: Exploring the Possibility
Geology & LandformThe Earth’s mantle is a layer of hot, dense rock that lies beneath the Earth’s crust. It extends from about 6.2 miles (10 kilometers) to 1,800 miles (2,900 kilometers) below the surface. The mantle is thought to be solid, although it can flow very slowly over long periods of time. Although we know a lot
