What else can I help you with?
Sedimentary rock Consisting of tiny concentric grains of limestone?
The sedimentary rock described is likely to be oolitic limestone, which forms from the accumulation of small spherical grains called ooids. Oolitic limestone typically forms in shallow, warm marine environments with high rates of evaporation. Its distinctive concentric structure is due to the successive layers of mineral precipitation around a central nucleus.
Ripple marks likely indicate that a rock formed?
Ripple marks likely indicate that a rock formed in a sedimentary environment, such as near a shoreline or in a river bed, where the movement of water created the distinct ripple pattern in the sediment before it hardened into rock. These marks provide information about the ancient depositional environment and the direction of water flow at the time of formation.
Which sedimentary rock type is likely to be formed in the most offshore environment?
Shale is the sedimentary rock type that is likely to be formed in the most offshore environment. Shale is made up of fine clay particles that settle in quiet water far from the influence of waves and currents.
If the sedimentary rock limestone is subjected to metamorphism what metamorphic rock will likely form?
Limestone can metamorphose into marble, a regional metamorphic rock, or into skarn, a contact metamorphic rock.
Is Water from an area which has a limestone and chalk strata most likely to be acidic?
No, water from an area with limestone and chalk strata is more likely to be alkaline, not acidic. Limestone and chalk are composed mainly of calcium carbonate which can increase the alkalinity of water through a process called calcification.

Shell imprints and bones can be found in what type of rock?
It's always in a sedimentary rock, but mostly they will be found in a limestone. Some limestones, like the 'shelly' limestone, will be more likely to contain shells than others, like the oolitic limestone (which is not made out of shells). Again, bones will tend to be found in sedimentary rocks, but the actual bones will tend to have dissolved and been replaced by rock minerals which precipitated out of solution to fill the 'mould' left by the bone (unless they were deposited recently, in which case you're more likely to find them in unconsolidated sediment like sand/mud).

Where would a major depositional basin be most likely to form?
a location where the crust has been downwarped by tectonic plate motion
Which rock is most likely to have grains cemented together?
Limestone
If the sedimentary rock limestone is subjected to metamorphism what metamorphic rock will likely form?
Limestone can metamorphose into marble, a regional metamorphic rock, or into skarn, a contact metamorphic rock.
What type of minerals most likely make up limestone?
Calcite
Which rock is most likely formed as a result of biologic process?
limestone

What kind of rock is likely to form where the heat from the granitic magma is conducted to the limestone country rock?
The metamorphosed limestone will most likely be a skarn or marble, both formed from contact with an intruding granitic magma.
What animal that lives in huge numbers of the north - east coast of Australia is likely to form a limestone in the future?
Coral is the animal that lives in huge numbers on the north-east coast of Australia and is likely to form a limestone in the future
