Document Summary
Filled with water, because theyre so low in topography. Collapses after it erupts, and creates a crater. With strata volcanoes: explosive eruptions, bombs, ash fall, pycroclastic flows, lahars, less frequent eruptions, and can often be predicted predictable, With shield volcanoes: far-spreading, with fast moving lava flows, continuous eruptions. Weathering and eroding any other rock type, to make sedimentary rock. Organic rocks made from organic material, left over fleshy parts of organisms. Weathering and erosion, linked together: can be mechanical weathering, chemical weathering limestone, and acid rain will cause a solution. Transportation: material will be weathered in one area, and then transported by gravity (rocks falling off), wind, water, ice (not so common now, but before it was, chemical weathering ions dissolved in groundwater. Deposition: ocean tends to be the last stop for most sediment, where it ends up last. Lithification: once its deposited, some sort of lithification will happen, going from sediment to rock how to classify the sedimentary rock.
