rhyolitic mama is associated with explosive volcanism and is ejected (blown out of) a volcano rapidly. Basaltic lavas are released during effusive volcanism that is not explosive, such as hawaii where the lave "flows" into the ocean slowly. Basaltic lavas have a lower silica content as well.
A shield volcano forms when layers of basaltic lava accumulate during a nonexplosive eruption. These volcanoes have gentle sloping sides and are usually characterized by their broad and flat shapes. Mauna Loa in Hawaii is a well-known example of a shield volcano.
gases emitted during volcano eruptions are basically oxides of shulphur,etc
The human animal is most abundant in Antarctica during the summer. As well several sea mammals and sea birds come to the beaches and beach areas to breed during the summer.
Dinosaurs
Trilobite
They were abundant on Earth during the Carboniferous.
A scoria cone volcano, also known as a cinder cone volcano, is the type of volcano that has small basaltic cones built during one short eruptive episode. These volcanoes are characterized by their steep sides and formed by the accumulation of volcanic debris, such as scoria and ash, ejected during explosive eruptions.
Ionized hydrogen and helium are the most abundant chemical elements in nebulae.
Mammoths and mastodons were abundant 10,000 years ago. Currently, we live in the Cenozoic era, which began 65.5 million years ago. Therefor, mammoths and mastodons were abundant in the Cenozoic era.
Mt Etna, one of the most active volcanoes in the world, primarily produces basaltic lava. This type of lava is low in silica content, which makes it relatively fluid and able to flow long distances. Etna's eruptions can range from effusive, producing lava flows, to explosive, producing ash plumes and pyroclastic flows.
Metazoans were abundant during the Vendian Period.
