Answer:
America is located in the Noerthern and Western Hemispheres
Explanation:
Ok so there are two lines that cut the earth in half, one that goes horizontally called the equator, and one that goes vertically called the prime meridian. the equator divides the world into the northern hemisphere on the top half, and the southern hemisphere on the bottom half. the prime meridian divides the world into the western hemisphere on one side, and the eastern hemisphere on the other. so those two lines kind of make a grid, if you know what i mean. if you look, north america is located on the noethern and western hemisphere, because it is north of the equator, and west of the prime meridian. thank me
, the world was made up of a single continent through most of geologic
time. That continent eventually separated and drifted apart, forming
into the seven continents we have today. The first comprehensive theory
of continental drift was suggested by the German meteorologist Alfred Wegener
in 1912. The hypothesis asserts that the continents consist of lighter
rocks that rest on heavier crustal material—similar to the manner in
which icebergs float on water. Wegener contended that the relative
positions of the continents are not rigidly fixed but are slowly
moving—at a rate of about one yard per century.
