Answer:
The counties of Michigan are organized in a grid pattern because the internal subdivision of the state followed the pattern of surveying established by the Land Ordinance of 1785, which established a rectangular division of the lands of the Northwest Territory, with the objective of facilitating an equal distribution between settlers who would be sent there to populate the region west of the Appalachians.
Thus, the Northwest Territory began to be subdivided into a rectangular shape, and the counties in this region began to take this shape. So when Michigan was established as a state, its counties (as well as those of the other Midwest states) continued to maintain this rectangular shape.
Answer:
The answer is Option C: Index fossils.
Explanation:
Index fossils are used to identify geologic periods or faunal stages in rock layers. These fossils must have a wide geographic distribution and manifest obvious evolutionary trends to help geologists and others who need this geological data to better understand the time scale and to pinpoint a time period. For example, ammonites were common during the Mesozoic Era, but they were extinct by the Cretaceous period. Geologists would use ammonites to help determine this time frame if present.
By reducing the need for fossil fuels through the use of the ethanol biofuel.
