contour line, a line on a map representing an imaginary line on the land surface, all points of which are at the same elevation above a datum plane, usually mean sea level map: contour lines
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 are contour lines short answer?
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 A contour map is a map illustrated with contour lines, for example a topographic map, which thus shows valleys and hills, and the steepness or gentleness of slopes
What are the 3 types of contour lines?
Contour lines are of three different kinds They are the Index lines, Intermediate lines and the Supplementary lines
What is the best definition of a contour line?
Definition of contour line : a line (as on a map) connecting the points on a land surface that have the same elevation
What is the use of contour line?
The purpose of contour lines is to represent the tridimensional shape of the terrestrial surface on a bidimensional map Contour lines are the intersection of an horizontal plane parallel to the reference level and the topographical surface to describe
What is contour line Brainly?
Contour lines are an imaginary lines drawn on a map by joining all the same height points (above the mean sea level) on the earth It is a plane section representing 3D graph A contour line joins points of equal elevation (height) above a given level, such as mean sea level
What are Contour lines also called?
a line joining points of equal elevation on a surface Also called contour, level curve, level line
What are Contour lines Class 9?
Complete answer: Contour lines are the lines for joining points of equal height above or below the sea level Contour interval is the vertical distance between the two contour lines and these lines are next to each other
What is contour on a map?
Put simply, contour lines mark points of equal elevation on a map If you trace the length of a line with your finger, each point you touch is the same height above sea level If you were to walk the path of a contour line in real life, you would remain at the same elevation the whole hike, never traveling up or down
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 contour shading?
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 an example of contour?
: the outline or outer edge of something He loved the sleek/smooth/flowing contours of the car The map showed the contour of the coastline
What is a contour line on a map kids?
Contour lines are lines drawn on a map that show a change in elevation, and they show how steep or flat an area is More lines mean more change in elevation
What are contour lines Class 7?
Answer: (i) Contour lines are isolines of height (ii) These are drawn by joining the places of equal altitude (iii) These help in identification of land forms and their altitude from sea level (iv) These lines also help us to understand the nature and direction of the slope
What is the shape of contour lines?
At a stream junction, contour lines form a “M” or “W” shape This can be interpreted as two “V-shaped contours intersecting
What is a map answer?
A map is a visual representation of an entire area or a part of an area, typically represented on a flat surface Maps attempt to represent various things, like political boundaries, physical features, roads, topography, population, climates, natural resources and economic activities
What is contouring Class 8?
Class – 8 Subject – Geography Chapter – REPRESENTATION OF GEOGRAPHICAL FEATURES Synopsis: Contour – Brown continuous curved lines joining the places having the same height or elevation above the mean sea level It shows elevation, steepness and shape of the land It is shown with closely spaced contours
How do contours work?
Contour lines connect points that share the same elevation: Where they’re close together (they never intersect), elevation is changing rapidly in short distance and the terrain is steep Where contour lines are wide apart, elevation is changing slowly, indicating a gentle slope
Can contour lines cross or split?
Contour lines do not cross each other, divide or split 2 Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes
What does contour mean in drawing?
contour drawing, version of outline drawing, in which the artist, looking closely at the contour of an object, transfers it in one continuous line to paper without looking down to see what he is doing, except when he needs to place an internal feature such as an eye
What is the difference between contour line and cross contour line?
While contour lines describe edges, cross-contours describe form and volume These lines can follow planes of form, moving around and across objects as well as through them Think of a topographical map–the lines move across the terrain Cross-contour lines do the same thing
What is topography in geography?
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
What are contour lines ks3?
These are lines drawn on maps that join places of the same height Some contour lines have their height above or below sea level written on them It is possible to use them to see the shape of the land – if contour lines are close together the slope is steep, if they are far apart the slope is gentle
