Answer :

In geology we place the period of older time at the bottom of the legend, the Cincinnati Arch exposed north of Kentucky forms the strongest, oldest, least-broken geologic structure in the United States.

Kentucky, also known as the Commonwealth of Kentucky, is one of the Upper South states and is located in the Southeastern part of the United States. To the north, it shares boundaries with Illinois, Indiana, and Ohio; to the east, with West Virginia; to the south, with Tennessee; and to the west, with Missouri. The Ohio River serves as its northern boundary. Frankfort serves as the state's capital, while Louisville and Lexington are its two biggest cities. In 2020, there were roughly 4.5 million people living there. On June 1, 1792, Kentucky became the fifteenth state to join the Union, separating from Virginia in the process. The term "Bluegrass State" refers to the Kentucky bluegrass, a type of green grass that grows in many of the state's pastures and has supported the thoroughbred horse industry in the state's centre. Due to its favourable farming circumstances in the past, the state's central and western regions saw the creation of huge tobacco plantations similar to those in Virginia and North Carolina using slave labour during the antebellum South and the Civil War. Kentucky is eighth in the nation for the production of beef cattle, fifth for goat husbandry, and fourteenth for grain. Kentucky has also historically been a significant hub for the tobacco industry. The non-agricultural sectors of Kentucky's economy have grown in prominence in recent years, including auto manufacturing, energy fuel production, and healthcare institutions. In terms of the quantity of cars and trucks assembled, the state comes in fourth place among US states.
