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.

the first phase of the government’s plan for settlement was building the transcontinental railroad. the railroad provided a way to bring settlers and manufactured goods west and ship their agricultural and mining produce east. the transcontinental railroad was an essential artery for rapid development of the frontier.

the second phase of the government’s plan was a liberal land distribution policy that made it possible for many people to homestead. with these two key elements—transportation and cheap land—the government rapidly achieved its goal of persuading people to move west, settle on farms, and push back the frontier.

a characteristic is a deep cut in the earth or left over rock aka till.
