Contour lines that are relatively close together indicate a slope that is fairly steep. Contour lines that are further apart indicates a slope that is relatively flat .
What do closely spaced contour lines on a topographic map indicate quizlet?
What do closely spaced contour lines indicate ? They indicate a steep slope. What do widely spaced contour lines indicate ? They indicate a gentle slope.
What do closely spaced contour lines indicate on a map?
Closely spaced contour lines indicate steep slopes . Widely spaced contour lines indicate gentle slopes or relatively flat areas. A contour line that forms a closed loop with no other contour lines inside indicates a hilltop.
What do the contour lines on a topographic map best represent?
Contour lines are lines drawn on a map with equal elevation points, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows. It is useful because they show the form of the land surface on the map–its topography .
What does the spacing of contour lines imply?
Closely spaced in contour lines indicate the steep slopes , far contour lines represent gentle slopes. Contours are drawn at various intervals such as 20, 50,100 metres above the sea level. Contour spacing or counter intervals indicate the various landforms such as hills, plains and ridges.
What are the types of contour lines?
A. Contour lines are of three different kinds. They are the Index lines, Intermediate lines and the Supplementary lines .
How do you read contour lines on a topographic map?
- 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. ...
- Supplementary lines appear as dotted lines, indicating flatter terrain.
What are the two differences between index contour lines and regular contour lines?
The index contours are a darker or wider brown line in comparison to the regular contour lines. You’ll see the elevations marked on the index contour lines only. To determine elevations, pay attention to the amount of space in between lines . If the contours are close together, you’re looking at a steep slope.
When contour lines are far apart?
If contour lines are close together, it is a very steep slope; if they are far apart, it is a gradual slope .
What do V shaped contour lines indicate?
V-shaped contour lines indicate valleys, ravines, or gullies . Closely-spaced contour lines depict steep slopes. More widely- spaced contour lines indicate gradual slopes.
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 .
How do you explain topography?
Topography describes the physical features of an area of land . These features typically include natural formations such as mountains, rivers, lakes, and valleys. Manmade features such as roads, dams, and cities may also be included. Topography often records the various elevations of an area using a topographical map.
What is the importance of contour lines?
Contour lines are very important in teaching natural sciences because they represent relief in an accurate way . Relief is controlled by rock type and geological structures. These two factors influence in the location and shape of rivers, which in terms, help the development of soils and vegetation.
What is it called when contour lines are close together?
Contour lines that are relatively close together indicate a slope that is fairly steep . Contour lines that are further apart indicates a slope that is relatively flat. The area of the map above boxed in orange shows an area that has a fairly steep slope, while the area boxed in purple is a relatively flat area.
Can contour lines intersect?
Contour lines never cross .
They may come very close to each other (e.g. along a cliff), but by definition they may never cross each other. * This is because one location on the surface of Earth cannot be at two different elevations!
What two types of lines show elevation differences answer choices?
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.
