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
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.
Sedimentary rocks with ripple marks suggest that the rocks formed where?
Ripple marks in sedimentary rock were emplaced in sediments by near shore wave action, covered by additional sediments, and eventually lithified into a solid rock which becomes exposed by weathering and erosion of overlying material over large expanses of time.
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.
Which observation best shows that limestone was formed from ocean sediments?
The presence of marine fossils within the limestone is the best observation that shows it was formed from ocean sediments. Marine fossils like shells, corals, or sea creatures preserved within the rock provide direct evidence of its marine origin. Additionally, the presence of ripple marks or cross-bedding in the limestone can also indicate its formation in a marine environment.
What do ripple marks likely indicate that a rock formed?
Ripple marks typically indicate that a rock formed in a shallow, watery environment, such as a riverbed, lake, or coastal area. These features are created by the movement of water over sediment, leading to the formation of small, wavelike patterns. Consequently, the presence of ripple marks in sedimentary rocks suggests that they were deposited in conditions where currents or waves were active.

Ripple marks most likely to be observed in sandstone?
yes

Ripple marks in rocks are formed by?
They initially are formed by moving water which arranges sediment in patterned formations. If the ripples in the sediment are covered with other sediments before being obliterated, or if the ripple marks dry, and are then covered with subsequent sediments, they may eventually be preserved in the rock strata.

What information does mud cracks and ripple marks give us?
Mud cracks and ripple marks provide valuable information about past environmental conditions. Mud cracks indicate periods of drying and wetting in ancient sediment, suggesting fluctuating water levels. Ripple marks indicate the direction and strength of ancient currents, helping to interpret the depositional environment of a sedimentary rock.

What do ripple marks in sedimentary rock mean?
Ripple marks in sedimentary rocks indicate the presence of flowing water, such as in a river or a shallow sea. They form when sediments are deposited by the movement of water, creating distinctive ridges and troughs. Ripple marks can provide insights into the direction and energy of ancient water currents.
Which type of rock is likely to show ripple marks and fossils?
Sedimentary rocks show fossils, because of pre-existing life forms. They also show ripple marks due to weathering and erosion...
What are the wavy features found on sandstone?
The wavy features found on sandstone are known as cross-bedding or ripple marks. They are formed by the movement of water or wind, which creates layers of sediment that are inclined at an angle to the main horizontal layering of the rock. These features can provide information about the direction and intensity of the ancient currents that deposited the sediment.
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.
