What else can I help you with?
What is done to reduce soil erosion on steep slopes?
Contour Farming
What is a gentle slope?
When the contour lines are farther apart, this means that the slopes between them are gentle. On the other side, if the contour interval is smaller, the slope will be steep.
What are precipitous slopes?
Slopes that are dangerously high and/or steep.
Why do some stairs have steep slopes?
Usually, stairs are built with steep slopes only if there isn't enough room to build them with milder slopes.
Can steep slopes retain water?
Steep slopes generally have a reduced capacity to retain water due to gravity, which causes water to flow quickly downhill rather than being absorbed into the soil. However, certain conditions, such as vegetation cover and soil composition, can enhance water retention on steep slopes by promoting infiltration and reducing runoff. Additionally, features like terraces or contour farming can also help in managing water retention on steep terrains. Overall, while steep slopes can pose challenges for water retention, effective management practices can improve their capacity to hold moisture.

What does the spacing between contour lines tell you?
closely spaced contour lines indicate steep slopes, wider ones indicate gentle slopes
What does the spacing between contour lines tell?
closely spaced contour lines indicate steep slopes, wider ones indicate gentle slopes
Contour lines that are far apart indicate?
Contour lines that are far apart indicate gradual slopes, while contour lines that are close together indicate steep slopes.
What type of relief is indicated by contour lines that are very close together?
Steep slopes
What arrangement of contour lines shows that the land is steep?
The land is steep if the contour lines are close together
If Contour lines are close together the land has a gentle slope?
The closer the contours, the steeper the slope.
What is a gentle slope?
When the contour lines are farther apart, this means that the slopes between them are gentle. On the other side, if the contour interval is smaller, the slope will be steep.
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.
How close the contour lines are an indication of an area's what?
The proximity of contour lines indicates the steepness of the terrain in a particular area. Closely spaced contour lines suggest a steep slope, while widely spaced contour lines suggest a gentle slope.
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.
What landform is shown by many contour lines that are very close together?
On a topographical map, a contour line indicates a change in elevation. When the lines are close together, the elevation is changing rapidly.
