Document Summary
Volcanic gas: gaseous form; water vapor and carbon dioxide. Pyroclastic flow: a fast moving avalanche of a mix of hot ash and lava flow with debris that can move up to 450 mph; can be deadly. Lava flow: steady flow of hot lava. Volcanoes produced high amounts of co2 in the early earth. It was the most common type of gas in the early earth! Basaltic lava: fast flow; little silica; low viscosity. Rhyolitic dome: slow flow; blocky shape; high silica; high viscosity. The city of pompeii had a volcano erupt and the city was destroyed and the people died; pyroclastic volcano edimentary rocks form from particles called sediment (sand, salt, clay, etc. ), that are torn off from other rocks. Limestone source for limestone is calcium carbonate (caco3) The origin of limestone = plankton shells. Coal made of carbon and organic chemicals from plants. Clastic sedimentary rocks are primarily classified on the basis on grain size.
