Such a lake may cover a large area and be only a few inches deep, and that only after a heavy thunderstorm. Playa lakes and desert streams that flow only after rainstorms are called intermittent or ephemeral. Spletfold, in geology, undulation or waves in the stratified rocks of Earth’s crust. Stratified rocks were originally formed from sediments that were deposited in flat horizontal sheets, but in a number of places the strata are no longer horizontal but have been warped. Sometimes the warping is so gentle that the inclination of the strata is barely perceptible, or the warping … honoring employees on veterans day

Although the deposits of all four types of sediment support mechanisms are found in nature, pure grain flows are largely restricted to aeolian settings, whereas subaqueous environments are characterized by a spectrum of flow types with debris flows and mud flows on one end of the spectrum, and high-density and low-density turbidity currents on the other end. It is also useful in subaqueous environments to recognize transitional flows that are in between turbidity currents a… http://pages.geo.wvu.edu/~kammer/g3/Test2Questions.pdf honoring dictionarySpletThere are four types of transportation: Traction - large, heavy pebbles are rolled along the river bed.

SpletFigure 5.3.3: Transportation of sediment clasts by stream flow. The larger clasts, resting on the bottom (bedload), are moved by traction (sliding) or by saltation (bouncing). Smaller clasts are kept in suspension by turbulence in the flow. Ions (depicted as + and – in the image, but invisible in real life) are dissolved in the water.

SpletBed-load: gravel & sand carried along a river bed by traction and saltation. Biological weathering: breakdown of rock (see weathering) by the action of bacteria, plants and animals. Boulder clay: mixture of clay, pebbles and boulders deposited by ice sheets. "Bombs" - volcanic: lumps of rock and/or lava thrown out of a volcano during an eruption. SpletTraction is the geologic process whereby a current transports larger, heavier rocks by rolling or sliding them along the bottom. Thus, the grains and clasts interact with the substratum during transport. By contrast, saltation, a related sediment transport process, moves grains across the bottom by bouncing or hopping. The actual current carries the sediment load …

SpletRoundness During transport, the shape and outline of clasts continue to evolve as they are carried. Grains transported by currents such as wind, rivers, or waves, can move as suspended load, by saltation (jumping), and traction with the ground/bed.
