These lines in maps represent altitude thresholds. This means that everything colored the same within a closed line is within a set altitude range (e.g. 1500-1550 meters above sea level). Therefore, terrains with gentle slopes have wider lines than those with steeper slopes because, the number of lines needed to show the variations in altitude is smaller.

∙ 7y agoThe lines represent the elevations in standard increments, such as 2', 100' or 1000'. Therefore, the steeper the grade, the closer the lines. In other words, if a hill is very steep and the elevation increases by a given amount over a lateral distance of 100 yards, for instance, the lines will be close together so as to represent how quickly the elevation rises. If the elevation increases by the same amount, but over a lateral distance of 1000 yards, the lines will be further apart.

Why do silica-poor magmas produce broad volcanoes with gentle slopes?
Silica poor magma is generally low in viscosity, and is therefore more fluid. The lava can travel a great distance before solidifying, thus creating broad gentle slopes.
How can you determine whether the contour on a tropographic map show a gradual slope?
You can tell if a landform has a steep or gentle slope by looking at it. If the hill is small, it is not steep. A steep slope would be at more of an incline.
Why does contour lines that show a steep cliff look different from contour lines that show a gentle slope?
one thing is that the countour lines that are steep cliff are more curved to the left side and the other ones the ones that show a gentle slope are curved to the right side
How does a contour tour map show whether a slope is gently or steep?
If the contour lines are far apart, then that indicates the land has a gentle slope (low slope).
Why do gentle sloping wide rivers have more meanders than steep fast-flowing rivers?
Fast flowing rivers are more erosive and are light on the deposition of sediments. Slow flowing rivers allow for the deposition of sediment which create the meanders.
Why do you think gentle slopes are shown with more widely spaced lines than steeps slopes are?
Contour lines on a on a topographic map indicate elevations. Since elevation changes gently on gentle slopes the contour lines are further apart. Elevation changes rapidly on a steep slope so the contour lines are closer together.
How do lines show steep and gentle slopes?
Contour lines are lines that join up points on a map that represent points on Earth's surface that have equal height. The distance between the contour lines gives an indication of how much the height changes over a horizontal distance. In other words it shows you how steep or gentle the slope is.As such a steep slope will be marked by closely spaced contour lines and a more gentle slope will have more widely spaced contour lines.
Why do gentle slopes have more widely spaced lines than steep slopes?
Presumably the questions refer to contour lines. If that is the case, the answer is as follows: Contour lines are lines drawn at selected heights on a map. They are lines that join points at the same height above the meas sea level. A gentle slope is one that does not rise (or fall) as rapidly as a steep slope. That is to say, you have to travel a greater horizontal distance to gain (lose) the same amount of vertical distance or height. So, with a gentle slope, you have to travel a greater distance to get from one contour to the next and so the lines are less close together.
How do you compare slopes math wise?
Mathwise, you would want to represent a slope with a number, in such a way that the steeper slope would have a larger number. That way, you could look at the numbers of two or more slopes, and just from the numbers, you could tell mathwise which slope is more steep or less steep, and whether it slopes up or down.
Do steep hills erode faster than gentle hills?
Steep Hill Erodes Faster. The Water Picks Up Speed And More Energy To Wear Away The Earth. Generally, hills will be steep because they are made of resistant rock; whereas gentle hills will have that shape because they are made of rock that is easily eroded. Hence steep hills will not necessarily erode faster than gentle ones. However, if a hill is steep because it has recently been formed by tectonic activity, and it comprises soft rock, it will erode faster than a more gentle hill of the same material.

What are the different causes of soil erosion pertaining to steeps slopes and plateaus region and suggest remedial measures?
over grazing and not maintaing the soil properly can lead to soil errosion. in steep slopes the soil errosion can be more as when the water flows the soil can be erroded but it can be prvented by planting more and more trees
