Major reef builders in tropical areas today
What are corals?
Type of alluvial fan characterized by large coarse-grained lobes
What are debris-flow fans?
Mode of sediment accumulation that occurs on deltas when sea level drops
What is progradation?
Major subaqueous conduits of continental sediments to the deep ocean
What are submarine canyons?
The lowest level to which water can erode
What is base level?
What are bryozoans?
Process that may remove fine grained material and leave coarse fragments behind on a fan surfaces
What is winnowing?
Type of delta with large lobes that forms in river-dominated systems
What are bird's foot deltas?
The depth at which the rate of CaCO3 from the surface equals the rate of dissolution
What is the CCD?
Fluvial depositional features characterized by lateral accretion and cross bedding
What are point bars?
A common type of "baffler" in reef systems about which sediment can accumulate
What is seagrass?
Type of alluvial fan that often has well-sorted and cross-bedded deposits in addition to gravel
What is a stream-flow dominated fan?
Activity that results in smooth to triangular shaped deltas
What are waves?
The aspect of the ocean that determines where calcareous vs clay vs course terrigenous material accumulates
What is bathymetry?
Channel form dominated by suspended load rather than bedload
What are meandering streams?
Calcified sponges with horizontal calcite layers that were major reef builders in the Paleozoic
What are stromatoperoids?
Dating method that relies on defects in the mineral lattice of quartz and feldspar grains
What is OSL dating?
What is deforestation?
These undersea features are characterized by lobes, debris flows, turbidites, and channel systems
What are submarine fans
Floodplain features that form graded deposits with climbing ripples
What are crevasse splays?
Part of a reef where grainstone is common
What is the reef flat (or reef apron)?
The factor that limits Black Mountain fan size on the eastern side of Death Valley.
What is accommodation space?
Type of flow that results when the density of river water is less than the basin it empties into
What is hypopycnal flow?
The largest submarine canyon on Earth that dwarfs the Grand Canyon
What is the mighty Zhemchug?!
Mineral nodules often found in flood plains where drainage is poor
What is siderite?
