How did the Ozark Plateau form?
Regional SpecificsThe region is characterized by wooded, rolling hills formed by the erosion of an uplift called the Ozark Dome. Soils in the region, formed mostly from the weathering of carbonate rocks, support forests of oak, pine, and hickory. How did the Ozark Mountains form? The Ozarks were formed in a different way. They are the

What are the two mechanical layers of the earth?
Regional SpecificsMechanical Layers Layer Depth Lithosphere 0-100 km Asthenosphere 100-350 km Soft plastic *note: The mantle is not liquid! Mesosphere 350-2900km stiff plastic Outer Core 5100-6370 km solid What are earth’s 2 main layers? The Earth’s Structure The crust. This is the outside layer of the earth and is made of solid rock, mostly basalt and
What causes poorly sorted sediment?
Regional SpecificsStream deposits are usually poorly sorted because the energy (velocity) in a stream varies with position in the stream and time. Where is poorly sorted sediment found? At the end of a glacier, where ice is melting as fast as it is being supplied from upstream, the sediments are deposited in a terminal moraine, a
What has the biggest effect on the viscosity of lava?
Regional SpecificsTemperature: The hotter the lava, the lower the viscosity (the thinner it is). The cooler the lava, the higher the viscosity (the thicker it is). Composition: he more felsic the lava (the more silica in the lava), the higher the viscosity because silica forms chains in the cooling lava even before it crystallizes. What increases
Which mineral is found in rhyolite and andesite?
Regional SpecificsThe mineral assemblage is predominantly quartz, sanidine, and plagioclase. It is the extrusive equivalent to granite. Magma with the composition of rhyolite is extremely viscous, due to its high silica content.…Rhyolite. Composition Secondary Biotite and hornblende Which mineral can be found in all sample of rhyolite and andesite? Andesite is always rich in plagioclase, and
