answer:Submarines are different from other types of battleships because they can operate underwater, allowing them to be stealthy and avoid detection. Additionally, submarines are typically smaller and more maneuverable than other battleships, but they are also more vulnerable to certain types of attacks.

answer:Archaeological dating using stratigraphy involves studying layers of soil and rock (strata) to determine the relative age of artifacts and fossils discovered within those layers. The basic idea behind stratigraphy is that older layers are found beneath younger layers, since each layer is deposited on top of the previous layer over time. Archaeologists can use a variety of techniques to analyze these layers, including excavation and recording of the physical position of artifacts and fossils within the strata, as well as analysis of the materials and sediment found in each layer. By comparing the different layers to one another, archaeologists can determine the relative order of events that occurred at the site and use this information to establish a chronological sequence of events. This method provides relative dating, but to determine absolute dating, artifacts from the layers must be analyzed using other dating methods, such as radiocarbon dating, thermoluminescence or dendrochronology.
