Capillary waves (ripples) in water Ripples on Lifjord in Øksnes Municipality, Norway Capillary waves produced by droplet impacts on the interface between water and air.. A capillary wave is a wave traveling along the phase boundary of a fluid, whose dynamics and phase velocity are dominated by the effects of surface tension.
Symmetrical ripple. Although symmetrical ripples are also called bi-directional ripples there is a difference between them. Bi-directional ripples are rarely symmetrical due to the difference in force of the two directions, where as the wave formed or oscillation ripples form from the circular water movement pattern of water molecules.
Like the sinuous ripples, this form of ripple is created by unidirectional flow with the dip at an angle to the flow as well as downstream. Linguoid / Lunate Linguoid ripples have lee slope surfaces that are curved generating a laminae similar to caternary and sinuous ripples. Linguoid ripples generate an angle to the flow as well as downstream.
Those seismic waves are like ripples on a pond, the USGS said. The earthquake will be strongest at its epicenter, the point on the surface directly above where the quake started, and the effects ...
For example, when leaves alternate up a stem, one rotation of the spiral touches two leaves, so the pattern or ratio is 1/2. In hazel the ratio is 1/3; in apricot it is 2/5; in pear it is 3/8; in almond it is 5/13. [56] Animal behaviour can yield spirals; for example, acorn worms leave spiral fecal trails on the sea floor.

Giant current ripples (GCRs), also known as giant gravel bars or giant gravel dunes, [1] are a form of subaqueous dune. They are active channel topographic forms up to 20 m high, which occur within near- thalweg areas of the main outflow routes created by glacial lake outburst floods . [ 2 ]
Ripple marks: Ripple marks are small ridges of sediment that form due to wind or water blowing over loose sediment in either a current or wave pattern. Aeolian ripples result from high velocity winds which form fine, well-sorted grain particles into long, flat, asymmetrical ripples. [citation needed]
2005, 4). More than 11,000,000 Hispanic children are currently between the ages of 5 and 17. In terms of education policies that impact Hispanics, several major trends stand out: Low enrollment of Hispanic children in early childhood programs and kindergarten. Hispanic students tend to be less likely to be enrolled in these kinds of programs
