A topographical map, or "topo" map, shows landscape features such as ground elevations and waterways.dhdjdjjj
Cartography is the science of map reading.
A topographical map gives you the third dimension of altitude.
The answer is ON THE MAP. YOU have the map. The internet does not. Try thinking before you ask for help on your homework.
we make map to know find the countries, seas,continents.from the map we can find anything wher they are situated.
flow map for routes....isopleth,climograph,ergograph for weather...
The answer is ISOPLETH, does this help with the Mail crssword
Isopleth
Isopleth
Five types of thematic maps: Choropleth Map, Proportional or Graduated Circle Map, Isoline Map, Dot Map, and Dasymetric Mapping.
Isopleth lines, specifically isotherms, on a weather map indicate areas where the temperature is the same. These lines connect points of equal temperature, helping to visualize temperature patterns across the map.
Choropleth. Proportional symbol. Isarithmic or Isopleth. Dot. Dasymetric.

The lines that connect points having the same elevation are a kind of isopleth called contour lines, or contours.The closer that the lines are on the map the steeper the terrain is.
Acontour line (also level set, isopleth, isoline, isogram or isarithm) of a function of two variables is a curve along which the function has a constant value.[1] In cartography, a contour line (often just called a "contour") joins points of equal elevation (height) above a given level, such as mean sea level.[2] A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness of slopes.[3] The contour interval of a contour map is the difference in elevation between successive contour lines.[4] A contour interval is basically the same thing.
A contour line (also known as isopleth) on a topographic map connects points of equal elevation or depth. The steepest way up or down is in the direction perpendicular to the contour line at any given point. This gradient on a topographic map is at its greatest when the lines are close together, thus the slope is steepest. Note that a contour map does not have to be topographic. Any value mapped in two or three dimensions such as temperature, barometric pressure, or wind speed can have contour lines connecting adjacent points of equal value. Again, moving away from a contour line in a perpendicular direction will yield the greatest change in the value of the quality being recorded.
An imaginary line marking the simultaneous development of a thunderstorm, as noted by observing the time when the thunder is heard at different places, is called an isobront.
