What connect points of equal elevation on a topographic map?
The distinctive character- istic of a topographic map is that the shape of the Earth’s surface is shown by contour lines. Contours are imag- inary lines that join points of equal elevation on the surface of the land above or below a reference surface, such as mean sea level.
Does a contour line connects points of equal elevation?
The light brown lines on the topographic map are called contour lines. A contour line connects points of equal height above sea level, called elevation. For example, a 600′ (six hundred foot) contour line on a map means that every point on that contour line is 600′ above sea level.
How do you describe a contour line?
Contour lines are lines drawn on a map connecting points of equal elevation, meaning if you physically followed a contour line, elevation would remain constant. Contour lines show elevation and the shape of the terrain. The line you see will look like a contour line on a topographic map.
What two types of lines show elevation differences answer choices?
Topographic maps have contour lines that connect points of identical elevation above sea level. Contour lines run next to each other. Adjacent contour lines are separated by a constant difference in elevation, usually noted on the map.
What are the five rules of contour lines?
Rule 1 – every point of a contour line has the same elevation. Rule 2 – contour lines separate uphill from downhill. Rule 3 – contour lines do not touch or cross each other except at a cliff. Rule 4 – every 5th contour line is darker in color.
What is the difference between two contour lines called?
Two contour lines next to one another are separated by a constant difference in elevation (such as 20 ft or 100 ft). This difference between contour lines is called the contour interval. The map legend gives the contour interval.

What are Hachure lines?
Hachures are short lines laid down in a pattern to indicate direction of slope. When it became feasible to map rough terrain in more detail, hachuring developed into an artistic speciality.…
What are the lines on a topographic map called?
A contour line or isoline connects points on a map that are of equal value. Examples of contour lines or isolines are isobars (pressure) and isotherms (temperature). Perhaps the prototypical example of a contour line is that which connects points of equal elevation (that is, height above sea level).
Which is contour line connects two equal values?
Generally speaking, a line that connects 2 equal values can be considered an isoquant. . . . An isoquant (derived from quantity and the Greek word iso, meaning equal) is a contour line drawn through the set of points at which the same quantity of output is produced while changing the quantities of two or more inputs
What is the ISO word for a contour line?
An “iso-” word for a contour line that connects points of equal elevation. A contour line or isoline connects points on a map that are of equal value.
