Answer:
The mean center of population is the place where an imaginary, flat, weightless, and rigid map of the United States would balance perfectly if all residents were of equal weight. Historically, the movement of the center of population has reflected the expansion of the country, the settling of the frontier, waves of immigration and migration west and south. Since 1790, the center of population has moved steadily westward, angling to the southwest in recent decades.

NOTE: The Proclamation Line of 1763 limited British settlement to areas east of the Appalachian Mountains. Alaska and Hawaii were not included in the calculation of the mean center of population until 1950. Puerto Rico was not included in any decade.

The answer is B. The lines of Latitude are about 69 miles apart. Each line of latitude is 1 degree of the angle of circumference of the earth, with parallel latitude lines lined up going East-West. Since the lines are stacked up north to south, your latitude describes your North/South position on the earth. Since these lines are parallel, their distance in generally constant.
Lava cools more rapidly above ground than it does underground because it's much colder above ground than it is underground, speeding up the process.
Think about it this way: If you put a cup of water in two freezers, and Freezer A had a lower temperature than Freezer B, the water in Freezer A would freeze quicker because it is in a colder environment. Hope this helps!
