What is an Isoline provide an example?
Isoline. A line of constant value on a map or chart . Examples include isobar (equal barometric pressure), isotherm (equal temperature), and isohyet (equal precipitation).
In this way, what are called Isolines?
Isolines are lines drawn to link different places that share a common value. The prefix ‘iso’ is a greek word meaning equal, so an isoline must be a line joining equal points. For example, a line drawn on a map to join up all the places that are the same height above sea level is called a contour.
Similarly, what is Isoline in biology? An isoline is a line that connects points of equal value. For instance, the brown contour lines on a topographic map connect points of equal elevation. Isobars are used to show the distribution of air pressure . isophene: a line representing points where biological events occur at the same time, such as cops flowering.
Herein, what are Isolines used for?
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.
Do Isolines ever end?
Isolines never end, except at the edge of a map. 5.) The change in value from one isoline to the next is always the same.

What do u mean by topography?
Topography is a detailed map of the surface features of land. It includes the mountains, hills, creeks, and other bumps and lumps on a particular hunk of earth. Topography represents a particular area in detail, including everything natural and man-made — hills, valleys, roads, or lakes.
Who created Isolines?
An isotherm at 0 °C is called the freezing level. The term was coined by the Prussian geographer and naturalist Alexander von Humboldt, who as part of his research into the geographical distribution of plants published the first map of isotherms in Paris, in 1817.
What are ISO Heights?
Isohypse (aka height contour) The geopotential height is the distance above the Earth’s surface if it was a perfect and flat sphere. Isohypse are shown on a constant pressure surface. For example, when looking at a 850 mb chart, all isohypses no matter their value are located at 850 mb.
What is a contour line drawing?
Contour drawing, is an artistic technique used in the field of art in which the artist sketches the style of a subject by drawing lines that result in a drawing that is essentially an outline; the French word contour meaning, “outline”.
What is isopleth map?
n. ~ A map that uses lines or colors to indicate areas with similar regional aspects. 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 on a topographic map?
Topographic maps are detailed, accurate graphic representations of features that appear on the Earth’s surface. These features include: cultural: roads, buildings, urban development, railways, airports, names of places and geographic features, administrative boundaries, state and international borders, reserves.
What is a Cartogram map?
A cartogram is a map in which some thematic mapping variable – such as travel time, population, or GNP – is substituted for land area or distance. The geometry or space of the map is distorted, sometimes extremely, in order to convey the information of this alternate variable.
What are the three types of Isolines?
There are 5 major types of Isolines :
- Isotherms (lines that connect points of equal temperature).
- Isobars (lines that connect points of equal air pressure).
- Contour Lines (lines that connect points of equal elevation).
- Parallels (lines that connect points of equal latitude).
Why do Isolines never cross?
Answer and Explanation: Contour lines never cross on a topographic map because they represent the same elevation of the land. A particular point of land cannot be at more than one elevation, so only one contour line will pass through that spot.
What is ISO contour?
An “iso-” word for a contour line that connects points of equal elevation. single-word-requests. 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).
What is a Isotach?
Definition of isotach. : a line on a map or chart connecting points of equal wind speed.
What do isobars join?
Isobars are lines on a weather map joining together places of equal atmospheric pressure . On the map the isobar marked 1004 represents an area of high pressure, while the isobar marked 976 represents an area of low pressure. The numbers measure the atmospheric pressure in millibars.
What are Isolines in physics?
Isolines are lines that connect points of equal values. In the topographical map, points of equal elevation are connected. In this diagram, points of equal gravitational potential energy are connected with a line.
What are the three types of lines used on a topographic map?
There are 3 kinds of contour lines you’ll see on a map: intermediate, index, and supplementary.
- 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 is a reference map?
A reference map shows the location of the geographic areas for which census data are tabulated and disseminated. The maps display the boundaries, names and unique identifiers of standard geographic areas, as well as major cultural and physical features, such as roads, railroads, coastlines, rivers and lakes.
What is an Isoline interval?
isoline interval. the value of the spacing between to consecutive isolines.
What is Isoline in plant breeding?
Definition of Multiline Breeding: Isogenic lines or isolines refer to those lines that are genetically identical except for the allele at one locus. In other words, isogenic lines have only one gene difference. The use of multiline cultivars was first suggested in oats by Jensen in 1952.
What is Isohyets in geography?
An isohyet is a line on a map which connects points that have the same amounts of precipitation in a given period or for a particular storm. A contour line is also known as an isarithm, isoline, or isopleth, and it is contour line on a map which represents an imaginary line on the land’s surface.
