Current ripple marks, unidirectional ripples, or asymmetrical ripple marks are asymmetrical in profile, with a gentle up-current slope and a steeper down-current slope. The down-current slope is the angle of repose, which depends on the shape of the sediment.
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.
Asymmetrical ripple marks These are created by a one way current, for example in a river, or the wind in a desert. This creates ripple marks with still pointed crests and rounded troughs, but which are inclined more strongly in the direction of the current. For this reason, they can be used as palaeocurrent indicators.
As of 4:18 p.m. ET, the price of XRP (CRYPTO: XRP) traded 5.6% higher from late afternoon yesterday for a few different reasons. Part of the reason for XRP's strong performance today appears to be ...
Giant current ripple marks are large scale analogues of small current ripples formed by sand in streams. Giant current ripple marks are important features associated with scablands . As a landscape component, they are found in several areas that were previously in the vicinity of large glacial lakes.
There's no doubt that President-elect Donald Trump's victory on election night was a major catalyst for crypto in the year's final months. After underperforming the sector for several years, XRP ...
Ripple has also rolled out a stablecoin called RLUSD that can be used on the XRP ledger and Ethereum's blockchain. Ripple's Senior Vice President of Stablecoins Jack McDonald told CNBC that XRP ...
Bidirectional wave ripple, Nomgon, Mongolia. A paleocurrent or paleocurrent indicator is a geological feature (typically a sedimentary structure) that helps one determine the direction of flowing water in the geologic past. This is an invaluable tool in the reconstruction of ancient depositional environments. [1]
