Answers to map questions Define the following terms on your own paper. (1-7)

Prime Meridian Meridian of 0 degrees, the line from which all lines of longitude are measured.. The meridian of Greenwich, England, is the internationally accepted prime meridian on most charts. However, local or national prime meridians are occasionally used.

International Dateline The International Date Line is the imaginary line on the Earth that separates two consecutive calendar days. That is the date in the Eastern hemisphere, to the left of the line, is always one day ahead of the date in the Western hemisphere. It has been recognized as a matter of convenience and has no force in international law.

Equator

An imaginary line around the Earth forming the great circle that is equidistant from the north and south poles; "the equator is the boundary between the northern and southern hemispheres"

Hemisphere Hemispheres are half of the earth's surface. There are four hemispheres: The northern hemisphere (north of the equator); the southern hemisphere (south of the equator); the eastern hemisphere (east of the prime meridian); the western hemisphere (west of the prime meridian).

Tornado Alley Tornado Alley is the designation of the American Meteorological Society for the area of the United States in which tornadoes are most frequent. It encompasses the great lowland areas of the Mississippi, the Ohio, and lower Missouri River Valleys. Although no state is entirely free of tornadoes, they are most frequent in the Plains area between the Rocky Mountains and Appalachians.

Ring of fire The regions of mountain-building earthquakes and volcanoes which surround the Pacific Ocean. Sometimes referred to geographically as the Pacific Rim.

8. What are the three types of map projections and draw the shape of each. Mercator Projection

The Mercator projection has straight meridians and parallels that intersect at right angles. Scale is true at the equator or at two standard parallels equidistant from the equator. The projection is often used for marine navigation because all straight lines on the map are lines of constant azimuth. Azimuthal Projection

Azimuthal equidistant projections are sometimes used to show air-route distances. Distances measured from the center are true. Distortion of other properties increases away from the center point.

Conic Projection

A conic projection that distorts scale and distance except along standard parallels. Areas are proportional and directions are true in limited areas. Used in the United States and other large countries with a larger east-west than north-south extent. 9. What direction do lines of latitude run?

Imaginary lines that cross the surface of the Earth parallel to the Equator, measuring how far north or south of the Equator a place is located.

10. What direction do lines of longitude run?

An imaginary great circle on the surface of the earth passing through the north and south poles at right angles to the equator; "all points on the same meridian have the same longitude"

11. Find the following locations in an atlas and write down their latitude and longitude.

New York City 4º N 73ºW Hong Kong 20ºN 11ºE London 32ºN 5ºW Moscow 45ºN 36ºE Sydney 0 S 0 E Lima 0 S 2º W
