What is the name of small waves formed on the surface of sand by the action of water or wind?
I think the answer is called ripple marks
How are ripple marks formed?
In general, ripple marks are those marks left by water or wind or a surface they have affected. Ripple marks caused by water may appear on rock, or on sand caused by water or wind. Use the link below for more information and some pics.

What makes Ripple marks in sandstone may form by heat action of?
Ripple marks in sandstone can form due to the heat action of hot fluids or gases moving through the sedimentary layers. This process can cause the sand grains to align in a ripple pattern as the sediment is compacted and cemented into rock over time.
What is the name for marks left by the movement of wind or waves over sediment?
The marks left by the movement of wind or waves over sediment are called "ripples" or "ripple marks." These features are often seen in various sedimentary environments, such as beaches and riverbeds, and are formed by the flow of water or air over loose material. Ripple marks can provide insights into past environmental conditions and sedimentary processes.
Where did sand from beaches come from?
Sand on beaches came from RIVERS.
Which arrow shows the direction that water was moving to make these ripple marks?
The arrow pointing away from the ripple marks indicates the direction in which water was moving to create them. This is because ripple marks form perpendicular to the direction of water flow.
What has the author Karl E B Lofquist written?
Karl E. B. Lofquist has written: 'A positive displacement oscillatory water tunnel' -- subject(s): Water tunnels, Sand, Transportation 'Sand ripple growth in an oscillatory-flow water tunnel' -- subject(s): Coast changes, Ripple-marks
Why do Caribbean beaches have black sand?
The beaches with black sand are volcanic in origin.
A geologist finds a section of rock that shows ripple marks What does the presence of ripple marks say about the area where the rock formed?
The presence of ripple marks indicates that the area where the rock formed used to be covered by moving water, such as a river, stream, or a wave-dominated shoreline. Ripple marks provide evidence of past water currents and can help geologists interpret the depositional environment of the rock.
Ripple marks most likely to be observed in sandstone?
yes
What do beaches have?
Sand
