I am glad that this article had instructions on how to use a comedone extractor though -- it is really important to not force the blackhead or pimple to try and come out, otherwise, you can end up causing scarring. Post your comments.
Report Abuse. that is a really broad question. mt st helens is a composite volcano. it does not have lava, it has magma. it isn't lava until it breaks the surface. the lava pretty thin and liquidy.
Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile and periodic explosive eruptions and effusive eruptions, although some have collapsed craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far due to high viscosity.The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma.ubduction-zone stratovolcanoes, such as Mount St. Helens, Mount Etna, and Mount Pinatubo, typically erupt with explosive force: the magma is too stiff to allow easy escape of volcanic gases. As a consequence, the tremendous internal pressures of the trapped volcanic gases remain in the pasty magma.
