Which is the correct side of a ripple?
The stoss is the side of a wave or ripple that has a gentle slope versus a steeper slope. Current always flows up the stoss side and down the lee side.
Where does the current flow in a ripple?
The current flows down the lee side. The stoss is the side of a wave or ripple that has a gentle slope versus a steeper slope. Current always flows up the stoss side and down the lee side. This can be used to determine current flow during the time of ripple formation. Ripple marks in Cretaceous Dakota Formation, east side of Dinosaur Ridge.
What are the ripple marks on Dinosaur Ridge?
The stoss is the side of a wave or ripple that has a gentle slope versus a steeper slope. Current always flows up the stoss side and down the lee side. This can be used to determine current flow during the time of ripple formation. Ripple marks in Cretaceous Dakota Formation, east side of Dinosaur Ridge. Scale bar on notebook is 10 cm.
Why do ripples dip in the same direction?
Scientists suggest current drag, or the slowing of current velocity, during deposition is responsible for ripple cross-laminae. Straight ripples generate cross-laminae that all dip in the same direction, and lay in the same plane. These forms of ripples are constructed by unidirectional flow of the current.
Why do I have ripples on my sidewall?
Because of that construction, you can sometimes see the sidewall ripples where the rubber compound presses tightly against the thin vertical spaces between the tightly wrapped ply cords. The bigger the tire and the more ply that it has, the more likely you will notice the sidewall undulation, much like the “six-pack” of a body builder.
How is the lee side of a ripple preserved?
Critically climbing ripples climb at an angle equal to that of the stoss slope and thus preserve the entire lee slope of the ripple. Supercritically climbing ripples have an angle of climb greater than the stoss slope thereby preserving both the stoss side and the lee side of the ripple form ( Figure 1 (b) ). Figure 1.
What causes ripples to dip in the same direction?
Scientists suggest current drag, or the slowing of current velocity, during deposition is responsible for ripple cross-laminae. Straight ripples generate cross-laminae that all dip in the same direction, and lay in the same plane.
Why do ripples not preserve the stoss slope?
Subcritically climbing ripples do not preserve any of the stoss-slope because the angle of climb is too low. Critically climbing ripples climb at an angle equal to that of the stoss slope and thus preserve the entire lee slope of the ripple.
