What is the highest degree of longitude that can be measured? a. 90°w or 90°e b. 90°n or 90°s c. 180°w or 180°e d. 180°n or 180°s

The correct answer is C. 180°W or 180°E

Explanation

Planet Earth with its spherical shape has been divided by imaginary lines to establish geographical locations, climatic zones and time zones. These imaginary lines are the Meridians and Parallels. The meridians are imaginary lines that go from the north pole to the south pole and divide the earth by 360 ° in length; of which 180 ° in length are towards the west and 180 ° in length are towards the east taking as reference point 0 ° the Greenwich Meridian, dividing the earth in eastern and western hemisphere.

On the other hand, the parallels are imaginary lines that divide the earth horizontally taking as reference the line of the equator or 0 °, this pattern divides the earth in the northern hemisphere and the southern hemisphere each with 90 ° latitude. So, the correct answer is C. 180°W or 180°E.

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.
