Bedforms are
often preserved in the rock
record as a
result of
being present in a
depositional setting.
Bedforms are
often characteristic...
- of
bedforms such as
ripples or
dunes in a
flowing fluid. The
fluid flow
causes sand
grains to
saltate up the
stoss (upstream) side of the
bedform and...
- In geology,
ripple marks are
sedimentary structures (i.e.,
bedforms of the
lower flow regime) and
indicate agitation by
water (current or waves) or directly...

varying speeds and
velocities produce different structures, are
called bedforms. In the

regime bedforms. As a result,
antidunes migrate in an
upstream direction,
counter to the

Antidunes are

bedforms, meaning...

These bedforms are
