Isolines, also referred to as
contour lines
, can be used to represent elevation on a map by connecting points of equal elevation, for instance. These imaginary lines provide a good visual representation of the terrain.
What does isoline mean?
:
a line on a map or chart along which there is a constant value
(as of temperature or rainfall)
What are 3 types of contour lines?
Contour lines are of three different kinds. They are
the Index lines, Intermediate lines and the Supplementary lines
.
What are lines of equal velocity called?
Isotherms, isotachs, etc. are all examples of
isopleths
. These are lines of equal wind speed. They are most often contoured in the upper levels of the atmosphere, especially at the jet stream level.
What are contour lines?
A contour line is
a line drawn on a topographic map to indicate ground elevation or depression
. A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
What are 4 types of contour lines?
- Isopleth. Isopleth on a contour map connects the places having the same value of some measurable quantity of geographical or meteorological phenomena. …
- Isohyet. …
- Isobar. …
- Isobath. …
- Isohaline. …
- Isotherm. …
- Isohel. …
- Isohume.
What are the 5 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 isopleth method?
Isopleth maps
simplify information about a region by showing areas with continuous distribution
. Isopleth maps may use lines to show areas where elevation, temperature, rainfall, or some other quality is the same; values between lines can be interpolated.
What is Isoline in sentence?
Isolines are
lines that are drawn to link different places that share a common value
. For example, a line drawn on a map to join places that share a common temperature is known as an isotherm.
What is Dot method map?
Dot method is
used when cartographing mass scattered events
. When marking some quantity of units of the event is mapped with the help of dots or more precisely with the help of circles. They are placed on the map in such points where this event is directly occur.
What are the 3 types of Isolines?
- Contour line: Joins points of the same height above ground.
- Isobath: Joins points of the same depth below water.
- Isobar: Joins points with the same atmospheric pressure.
- Isotherm: Joins points with the same temperature.
- Isobathytherm: Joins points with the same temperature under water.
What is Isonif?
A line on a climate map linking places
with equal snowfall
. …
What are wind lines called?
The lines around high and low pressure on a weather map are called
isobars
, or lines of equal pressure, as shown in the above image on the left. When isobars are close together it is very windy; when they are further apart, conditions are more calm. The wind around highs always blows in a clockwise direction.
What are the main types of contour lines?
- Index lines are the thickest contour lines and are usually labeled with a number at one point along the line. …
- Intermediate lines are the thinner, more common, lines between the index lines.

What 2 types of lines show elevation differences?
Contour lines
are used to show elevation on a topographic map. Lines or isolines on a map that connect points with the same elevation. What does each contour line on a map show? Each contour line shows a different elevation.
