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 ridge of poorly-sorted glacial till. Porosity is the amount of open space in a rock or sediment. The terms describing sorting in sediments very poorly sorted, poorly sorted, moderately sorted, well sorted, very well sorted have technical definitions and semi-quantitatively describe the amount of variance seen in particle sizes. Stream deposits are usually poorly sorted because the energy (velocity) in a stream varies with position in the stream and time. What products of weathering cover the majority of the surficial land areas of Earth's crust? Gravel and sand are both porous and permeable, making them good aquifer materials. - Composition = Shell fragments Cards. Which of the following correlate to transport distance: grain size and rounding, current strength, sorting, grain sphericity, deposition. What kind of sediments are found in deep marine deposits? - Rock Type = Biochemical Clastic slate, fine-grained, clayey metamorphic rock that cleaves, or splits, readily into thin slabs having great tensile strength and durability; some other rocks that occur in thin beds are improperly called slate because they can be used for roofing and similar purposes. nebraska softball roster; jacksonville, fl hurricane risk; summer hockey league hamilton; - Rock Type = Chemical Principles of sedimentology and stratigraphy.
