Earth Science Isolines Vocabulary Set
Field Map
a map of a particular field or region with specific properties
quantity
something that has magnitude, size, or amount
How to find the interval of an isoline
subtract the two isoline values that are next to each other
contour interval
the elevation difference between contours that are next to each other
isoline interval
the space between two points or values
Rules of isolines
1.Lines on a field map connect all of the points on the map of EQUAL VALUE (SAME NUMBER) 2. Isolines NEVER cross each other Close together = rapid change / steep incline Far apart = gradual change / shallow incline 3. Isolines stay in NUMBER order This allows us to predict missing numbers Lines connect to the margin
contour line
A line on a topographic map that connects points of equal elevation
Isoline
A map line that connects points of equal or very similar(the same) values.
topographic map
A map that shows the surface features of an area.
mountains
Formed by two continental plates colliding and forcing each other upwards.
Isotherm
Line drawn on a weather map that connects points having equal temperature(hot or cold?)
Elevation
height above sea level
purpose of topographic map
help us to see 3D landscapes in a 2D form; to see elevation; how we find mountains
Types of Isolines
isotherms, isobars, contour lines
Isobars
lines of equal pressure
