Over the epochs, indiana has migrated from below the equator to its current position well above. the state has been submerged under shallow seas more than once. this periodic rise and fall of waters over the land lead to the deposition of many layers of sediment and the formation of rock.

Indiana limestone rocks

Explanation:

Indiana is a state in the United State, within the North American region. Indiana has traveled from the near South polar region to its current position crossing the equator in its geological past. The state has been submerged periodically under the water. The continuous rise and fall of the sea level have led to the formation of the limestone rocks which is commonly known as the Indiana limestones. The area is highly rich in caves and quarries. These limestones are rich in fossil assemblages. In addition to this, there occurs tillite, a sedimentary type of rock comprised of glacial tills.
