What do closely spaced contour lines indicate quizlet?
What do closely spaced contour lines indicate? They indicate a steep slope.
What do the contour lines on a topographic map show?
The distinctive characteristic of a topographic map is the use of elevation contour lines to show the shape of the Earth's surface. Elevation contours are imaginary lines connecting points having the same elevation on the surface of the land above or below a reference surface, which is usually mean sea level.
How does the spacing of contour lines explain topography?
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. If the contours have wide spaces in between — or aren't there at all — the terrain is relatively flat.
When contour lines are closely spaced How is downhill indicated?
Closely spaced contour lines indicate a steep slope (Figure F-1). 2. Widely spaced contour lines indicate a gentle slope (Figure F-2).
Do closely spaced contour lines indicate a steep slope or a gradual slope?
Contour intervals reveal how much vertical distance there is between each contour line—closely spaced contour lines indicate very steep slopes. Contour lines that are sharply tapered indicate an uphill direction. Rounded contour lines typically indicate a downhill direction (gradual slope).
What does it mean when the lines are close together?
Widely separated contour lines indicate a gentle slope. Contour lines that are very close together indicate a steep slope. The figure above illustrates various topographic features.
What does contour lines are close together mean?
fairly steep 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.
What do closely spaced contour lines mean?
steep slopes 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.
When contour lines are closely spaced at the bottom of the slope and spaced further apart on the upper part of the slope then we have a?
Contour lines that are widely spaced at the top of the slope and closely spaced at the bottom of the slope depict a convex slope. Contour lines that are closely spaced at the top of the slope and widely spaced at the bottom depict a concave slope. 5.
What do close contour lines show?
Contour lines that are very close together indicate a steep slope.
When contour lines are spaced closer together that would indicate a flatter surface?
3.4. 55). In hilly areas, the contour lines are close together while they are wider apart on flat slopes. The closer the contour lines, the steeper the slope. The wider the contour lines, the flatter the slopes.
When the contour lines on a map are spaced closer together the slope of the profile becomes?
steep slopes Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes. 3.
When contour lines are closely spaced at the bottom?
Contour lines that are widely spaced at the top of the slope and closely spaced at the bottom of the slope depict a convex slope. Contour lines that are closely spaced at the top of the slope and widely spaced at the bottom depict a concave slope.
Do tightly spaced contour lines indicate high relief?
2. Closely spaced contour lines represent steep slopes, conversely, contour lines that are spaced far apart represent gentle slopes. 3. Contour lines trend up valleys and form a "V" or a "U" where they cross a stream.
When the contours are closely spaced and in a series represents?
Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope. When two or more contour lines merge with each other, they represent features of vertical slopes such as cliffs or waterfalls.
When contour lines are spaced far apart?
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 does it mean if contours are closely spaced?
steep slopes 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 does contour lines close to each other represent?
Closely spaced contours represent steep slopes while widely spaced contours represent gentle slope. When two or more contour lines merge with each other, they represent features of vertical slopes such as cliffs or waterfalls.
When contour lines are close together this means?
steep slope Lesson 2.3: Critical Reading. If you know how to interpret a contour map, it can tell you a lot about the shape of the land surface. The spacing of contour lines shows the slope of the land. Contour lines that are close together indicate a steep slope, where the elevation changes quickly over a short distance.
What is indicated by a closely spaced contours?
1. Closely spaced contour lines indicate a steep slope (Figure F-1). 2. Widely spaced contour lines indicate a gentle slope (Figure F-2).
What would the topography of an area be like if the contour lines were close together if they were far apart?
If contour lines are close together, it is a very steep slope; if they are far apart, it is a gradual slope.
How do contour lines indicate a stream?
The rule of V and U-shaped valleys All rivers flow downhill from higher to lower elevations, perpendicular to the contour line above them. As a rule of thumb, the V-shaped contour is pointing upstream (the opposite direction from the flow of a stream or river). The “V” shape contours indicate streams and drainage.
What are contour lines used for?
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.
