WebAn eruption of highly viscous (very sticky) magma tends to produce steep-sided volcanoes with slopes that are about 30–35°. That’s because the viscous volcanic material doesn’t flow that far from where it is erupted, so it builds up in layers forming a cone-shaped volcano known as a stratovolcano. WebHowever, rhyolite lavas occasionally erupt effusively to form lava spines, lava domes or "coulees" (which are thick, short lava flows). The lavas typically fragment as they extrude, producing block lava flows. These …

Types of Lava - Universe Today
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from 800 to 1,200 °C (1,470 to 2,190 °F). The volcanic rock resulting from subsequent cooling is also often called lava. WebThey are listed as follows in order of increasing degree of explosiveness: Icelandic. Hawaiian. Strombolian. Vulcanian. Pelean. Plinian. The Icelandic type is characterized by effusions of molten basaltic lava that flow from long, parallel fissures. Such outpourings often build lava plateaus. WebIt is the longest cave of this kind in Arizona. Geologists believe lava River Cave was formed sometime between 650,000 and 700,000 years ago when molten lava erupted from a volcano near the present day site of Michelback Ranch. When the lava came to the surface its temperature was hotter than 2,000 degrees Fahrenheit! evans scholarship merchandise
