The three different types of lava differ in composition and flow rate. Rhyolitic lava is the slowest moving type of lava, since it has a high viscosity due to a high silica concentration. Basaltic lava is the fastest moving lava because of its low viscosity resulting from a low silica content.
Lava. Lava is molten rock erupted at the ground surface. When molten rock is beneath the ground, it is called magma. 1  Lava flows are the effusive (non-explosive) outpourings of lava, and usually flow slower than walking pace. 2  Lava flow types include aâa, blocky and pahoehoe.ultiple types of eruptions can occur at each of New Zealandâs volcanoes-the eruption type can vary minute to minute.
