Visualizing Geology Chapter 8
A biogenic sediment formed from accumulation and compaction of plant remains
A combustible rock from the lithification of plant-rich sediments
A fan-shaped deposit of sediments dropped by a river or stream flowing out of a mountain range.
a triangular area of land formed from deposits at the mouth of a river
A lake where water is evaporated part of the year and drys up leaving salt
unstratified soil deposited by a glacier
Sediment that is carried and deposited by the wind.
the area where a freshwater stream or river merges with the ocean
a downslope movement of dense, sediment-laden water created when sand and mud on the continental shelf and slope are dislodged and thrown into suspension
Ooze composed of mostly the hard remains of organisms containing calcium carbonate
biogenous sediment composed of the silica based shells of single-celled animals and algae
One may be distiguished from the other by differences in grain size, grain shape, stratification, colour, chemical composition, depositional structure and/or fossils.
A linear, fault-bounded valley along a divergent plate boundary or spreading center
Wedge shaped accumulations of volcanicclastic sediment scraped of the subduction plate in thick slabs, seperated by thrust faults, which pile up like a stack of playing cardson the overriding plate
fragments of lithosphere incorporated into the melange of accretionary wedges
Sediment formed from fragmented rock and mineral debris produced by weathering and erosion.
The dissolved product of weathering precipitated from water (usually seawater) by chemical reactions and formed at or near its place of deposition.
Sediment that is composed primarily of plant and animal remains, or precipitates as a result of biologic processes.
The top or bottom surface of a rock stratum or bed.
The process that converts sediments into solid rock by compaction or cementation.
The process by which sediments are pressed together under their own weight.
The coolest kid on the planet!
The process in which minerals precipitate into pore spaces between sediment grains and bind sediments together to form rock.
heat and pressure break the bonds that join atoms in minerals and they join together differently as new bonds
any chemical or physical change that happens in a sedimentary environment subsequent to the original deposition of sediment.
A fine-grained clastic rock composed of silt plus a significant component of clay, which causes it to break readily along bedding planes.
