Longitude | The angular distance of a pace east or west of the meridian at Greenwich,England, or west of the standard meridian of a celestial Object. |
Latitude | The angular distance of a place north or south of the earth or a celestial object north or south of the celestial equator, usualy expressed in degrees and minutes |
Map Legend | A map key or legend is included with a map to unlock it. It gives you the information needed for the map to make sense.Maps often use sybols or colors to represent things, and the map key explains what they mean |
Map scale | Map scale refers to the relationship(or ratio) between distance on a map and the corresponding distance on the ground. For example, on a 1:100000 scale map 1cm on the map equals 1km on the ground |
Absolute location | Absolute location describes the location of a place based on a fixed point on earth. The most common way is to identify the location using coordinates such as latitude and longitude. Lines of longitude and latitude crisscross the earth |
Relative location | Absolute location,however, is a term with little real meaning, since any location must be expressed relative to something else. For example, longitude is the number of degrees east or west of the Prime Meridian, a line arbitarily chosen to pass through. |
Parallels | Each of the imaginary parallel circles of constant latitude on the earth's surface |
Medridians | A circle of constant longitude passing through a given place on the earth's surface and the terrestrial poles. |
Hemisphere | A half of the earth, usually as divided into northern and southern halves by the equator or into western and eastern halves by an imaginary line passing through the poles. |
Equator | An imaginary line drawn around the earth equally distant from both poles, dividing the earth into northern and southern hemispheres and constituting the parallel of latitude 0 |
Prime meridian | A planet's meridian adpoted as the zero of longitude. The earth's Zeron of longitude which by convention passes through greenwich, England |
North Pole | On the surface of the earth (or of a celestial object) that ends of the axis of rotation |
South Pole | On the surface of the earth that ends at the axis of rotation. |
