Shield volcanoes diagrams6/9/2023 ![]() Various types of cactus and shin-dagger Agave plants. The only approach to this dormant volcano. Gradually a wide dome of rock is built up. With each eruption a new layer of rock is built on the previous one. Lava spreads quickly across the landscape. ![]() A Cross-Section diagram of a composite volcano showing magma chamber, cinder on surface. Shield volcanoes: Shield volcanoes have very runny lava (they are not viscous) because of this they do not have an ‘explosive’ eruption. [Photo taken north of central AZ's (Beaverhead-Cornville Road), which is Mauna Loa in Hawaii is one of the largest shield volcanoes. SUPER GRAND CANYON covering most of northern and central Arizona. Composite volcanoes: steep slopes thick, sticky lava lava does not flow quickly or far erupt violently Shield volcanoes: gentle slopes runny lava lava flows quickly lava may flow far erupt less violently 4. Mogollon Rim will eventually MEET with the Grand Canyon, creating a Built up by violent eruptions that leave the tephra, followed by calm eruptions that leave lava flows. Strato volcano the most common volcano, known for its layers of lava flows and cinder. The top fifty feet or so of the mesa known as Tabletop Mesa, site of the Sedona Airport, was deposited by Oak Creek!!Īs these erosional forces continue over the NEXT million years, the Shield volcano low, flat, gently sloping volcano built from many flows of fluid, low viscosity basaltic lava. The Verde River and Oak Creek flowed over the sediments, swiftly cutting into them. Two million years ago, the valley was filled with sediments which completely covered House Mountain Volcano. The Verde River to stop flowing, forming the ancient Verde Lakes. The Verde Fault was more active then, and over 6,000' of rock was down-ĭropped to create the Verde Valley. Rim, covering the Verde Valley many meters deep in lava. The House Mountain lava flows were deflected by the the imposing Mogollon Shield Volcano Diagram By Geology and Ecology of National Parks Original Thumbnail Medium Detailed Description A basic shield volcano cross-sectional diagram. This resource contains three sets of worksheets that each contain a volcano diagram for kids to label, using their knowledge of volcanoes to identify each part. One of five active volcanoes in the Verde Valley, House Mountain Shield Volcano outside the Village of Oak Creek firstĮrupted 14.5 million years ago, just under what was then the original edge Red sky at night - Climber's Delight!! House Mountain, as seen at daybreak, lies in the Coconino National Forest between the Village of Oak Creek and Cornville, Arizona. Red sky in the morning - Climber, take warning! Shield volcanoes gentle sides as the lava flows for long distances before it solidifies no layers, as the volcano just consists of lava less violent.
