What type of boundary is a fault block mountain?
GeologyFault-block Mountains — form at divergent boundaries where two plates are moving and pulling apart. Many times this occurs along a fault line, which is a crack in the earth’s surface. Are fault-block mountains convergent? At a convergent boundary between two plates carrying continental crust, a collision between the continental fragments will result and form
What is special about Hawaii Volcanoes National Park?
GeologyHawai’i Volcanoes National Park, established in 1916, shows the sheer power of volcanoes ability to shape and re-shape our land. These processes rewrite the shape of the land. Coupled with the special human history and rare ecosystems found here, Hawai’i Volcanoes National Park is a special place in America to be sure. What are five
How can faulting act as a constructive force?
GeologyIs faulting constructive or destructive? Landforms are a result of a combination of constructive and destructive forces. Collection and analysis of data indicates that constructive forces include crustal deformation, faulting, volcanic eruption and deposition of sediment, while destructive forces include weathering and erosion. What are 2 examples of constructive forces? Constructive Forces Sediment (Deltas, sand
What is good about the modified Mercalli scale?
GeologyIn New Zealand, where earthquakes occur from near the surface right down to a depth of over 600 km, the Modified Mercalli intensity scale is a better indicator of an earthquake’s effects on people and their environment. What is good about the modified Mercalli scale measure? It measures the effects of an earthquake at a
Does an organism always have to be buried in sediment to become a fossil?
GeologyFor a fossil to form, an organism must be buried quickly so that any oxygen is cut off and its decay slows down or stops. In this investigation, students continue to think about how fossils form. Fossils are rarely the original unchanged remains of plants or animals. What are 3 requirements for an organism to
What is the zone above the snowline on a glacier called?
GeologyOn a glacier, the accumulation zone is the area above the firn line, where snowfall accumulates and exceeds the losses from ablation, (melting, evaporation, and sublimation). What are the four zones of a glacier? Terms in this set (3) Accumulation Zone. Area of net gain of snow and ice. More snow is added each year

What is a green rock called?
GeologyThe AGI Glossary of Geology defines greenstone (meta) : A field term applied to any compact dark-green altered or metamorphosed basic igneous rock (eg. spilite, basalt, gabbro, diabase) that owes its color to the presence of chlorite, actinolite, or epidote. What is the name of a green rock? Actinolite is a shiny medium-green silicate mineral

GeologyCultivated crops here include maize, sorghum, potatoes, pyrethrum, and peas, along with bamboo and eucalypts. In Java, tea is grown on high altitude volcanic soils. Deficiencies recognized in this environment include nitrogen, potassium, magnesium, sulfur, phosphorus, and zinc. What kind of plants grow around a volcano? Plants that grow in this volcanic soil can be
