What minerals make up breccia?
GeologySilica, calcite and iron oxides are the most common cementing minerals. There are many compositions of Breccia. The composition is determined by the mineral material and rock that the angular fragments were produced from. The composition of breccia can be influenced by the climate. What is the mineral composition of breccia? Breccia Type Sedimentary Rock
How likely is the Cascadia earthquake?
GeologyIt is simply not scientifically feasible to predict, or even estimate, when the next Cascadia earthquake will occur, but the calculated odds that a Cascadia earthquake will occur in the next 50 years range from 7-15 percent for a great earthquake affecting the entire Pacific Northwest to about 37 percent for a very … Is
Why do shield volcanoes have gentle slopes?
GeologyThe gentle slopes are the result of the low lava viscosity, allowing lavas to flow fast and far. The lava flows (pahoehoe and aa) commonly initiate their path from flank vents and fissures rather than from the summit. Why do shield volcanoes have very gently sloping sides? The main difference with shield volcanoes is that
What is stratigraphic method?
Geology and GeographyStratigraphy is a branch of geology concerned with the study of rock layers (strata) and layering (stratification). It is primarily used in the study of sedimentary and layered volcanic rocks. What is stratigraphy dating method? Stratigraphy: Assuming that soil layers in a deposit accumulate on top of one another, and that the bottom layers will

What do you do during an earthquake for kids?
GeologyWhat do you do in an earthquake for kids? Stay indoors until the shaking stops and you’re sure it’s safe to exit. Find an open spot. If you’re outside, the safest place in an earthquake is a clear spot away from buildings, trees, streetlights and power lines. Drop to the ground and stay there until
What are the effects of erosion and deposition on the environment?
Geologyreduced ability of the soil to store water and nutrients. exposure of subsoil, which often has poor physical and chemical properties. higher rates of runoff, shedding water and nutrients otherwise used for crop growth. loss of newly planted crops. What are the effects of erosion and deposition? The effects of these processes are as follows:
What are the 4 geological processes?
GeologyThe four major geological processes are impact cratering, volcanism, tectonics, and erosion. Earth has experienced many impacts, but most craters have been erased by other processes. We owe the existence of our atmosphere and oceans to volcanic outgassing. What are the 4 major geological processes? The four major geological processes are impact cratering, volcanism, tectonics,
What will not melt in lava?
GeologyIs there anything that doesn’t melt in lava? ANSWER : There are many materials that can withstand these temperatures: from metals such as (nickel alloys, iron alloys, tungsten and molybdenum alloys, even though these two might have oxidation issues, iridium, osmium, titanium, etc) to ceramics (silicon nitride, aluminum oxide, mullite, zirconia, etc). What does not
What spheres interact with the biosphere?
Geologythe atmosphere, which contains all of the planet’s air. These spheres are closely connected. For example, many birds (biosphere) fly through the air (atmosphere), while water (hydrosphere) often flows through the soil (lithosphere). How does the biosphere interact with another sphere? The biosphere receives gases, heat, and sunlight (energy) from the atmosphere. It receives water
