Final answer:
While we cannot see the image in question, if it displays oyster shells as in Figure 5.29, the rock is likely a form of sedimentary rock such as fossiliferous limestone. Limestone can be identified by its reaction with dilute acid and can contain visible fossils like oyster shells. (Option A).
Step-by-step explanation:
The student has asked for the name of the rock shown in the image. To identify the rock type accurately, we need to consider the visual cues provided in the image and any textual information from the provided exercise descriptions. For instance, if the rock has distinctive white spots which are oyster shells as mentioned in Figure 5.29, and knowing that oysters are found in sedimentary environments, we might conclude that if the rock in the image has such characteristics, then it is likely a form of sedimentary rock.
Among the options given:
- biochemical limestone may contain fossils such as oyster shells,
- sandstone is a clastic sedimentary rock composed of sand-sized particles,
- shale typically has fine laminations and may also contain fossils,
- conglomerate consists of rounded fragments cemented together.
A rock with oyster shells would most likely be a fossiliferous limestone. Different types of limestone, such as fossiliferous limestone, react with dilute acid which is a characteristic feature of limestones. Without the image, we can't provide a definitive answer, but we can suggest that if the image depicted white spots from oyster shells in the rock, it would likely be biochemical limestone. (Option A).
