GIVING A LOT OF POINTS PLEASE ANSWER ASAP In which two hemispheres is the United States? What are the functions of the following? Longitude Latitude Equator Hemispheres Tropic of Cancer Tropic of Capricorn Prime Meridian Greenwich, England International Date Line Artic Circle Antarctic Circle PLEASE ANSWER ALL THANK YOU.

North America is in the northern hemisphere

longitude - gives the East and West position of a point.

Latitude - give the north to south position of a point

Equator - it's a invisible line that goes around the earth, that has equal distance from the poles. It also divides the north and south hemispheres.

Hemisphere - the half of earths sphere, it's divided into four areas, north, south, east, and west. the invisible line crosses over all of them stretching to both poles.

Tropic of cancer - is the most northern latitude on earth, the sun can be seen overhead. it's 23.4 degrees north of the equator.

Tropic of Capricorn - is the most souther latitude on earth, you'll be able to see the sun directly over head. 23.4 degrees south of the equator.

Prime meridian - the invisible line that goes north to south at 0 degrees longitude. the prime meridian also separates the west and east hemisphere.

Greenwich - an area in London, England, that references the prime meridian line that passes through the town, the marked the area with a laser to imitate the line.

England international date line - an invisible line that goes from the north to south pole, i demonstrates the change of the calender day.

Arctic circle - the most southern latitude in the north hemisphere, the sun could be seen 24 hours a day.

Anarctic circle - is the most southern point of earth, parallel latitude and 66.5 degrees south of the equator

don't mind the spelling errors, I was typing fast.

a mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. this uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.a geomagnetic reversal is a change in a planet's magnetic field such that the positions of magnetic north and magnetic south are interchanged.
