Science Flashcards
Latitude
A line of measurement running east and west
Longitude
A line of measurement running north and south
Prime Meridian
Separates East from West
Is 0º in Longitude
Time Meridian
Greenwich Mean Time (GMT) is the time measured on the Earth’s zero degree line of longitude, or meridian. This runs from the North Pole to the South Pole
International Dateline
Is 180º in Longitude
North + South Poles
Separates North form South
Polaris
The star that is 90º in the North
Topography
a detailed description or representation on a map of the natural and artificial features of an area.
Contour Line
A line used to show depth and change in elevation o a Topographic map
Index Contour
index contours are bold or thicker lines that appear at every fifth contour line.
Contour Interval
A contour interval is the vertical distance or difference in elevation between contour lines.
Topographic Relief
relief mostly refers to how high mountains are.
Like that other thing we practiced with the vertical rollercoaster lines.
Depression Contour
A closed contour, inside of which the ground or geologic structure is at a lower elevation than that outside, and distinguished on a map from other contour lines by hachures marked on the downslope or downdip side.
Slope
In mathematics, the slope or gradient of a line is a number that describes both the direction and the steepness of the line.
Topographic Profile
A topographic profile or topographic cut is a representation of the relief of the terrain that is obtained by cutting transversely the lines of a topographic map. Each contour line can be defined as a closed line joining relief points at equal height above sea level.
You take a topographic map and make it a relief
