WebPyroclastic flows are a mixture of ash, volcanic gas, rocks, and lava that generally reaches temperatures of 390-1300°F (200-700 °C). These flows are mainly associated with volcanoes that have explosive eruptions, and they move down the volcanic slope at speeds greater than 50 miles per hour (80 kilometers per hour) . WebThe thick granitic lava that forms rhyolite often cools quickly while pockets of gas are still trapped inside of the lava. As the lava quickly cools, the trapped gas is unable to escape and forms cavities known as "vugs." …
