What else can I help you with?
What is a darker contour line usually every fifth line?
It makes it easier to count the number of contour lines.
How do index contours let you know if the land you are viewing are increasing or decreasing?
Each index contour has an elevation associated with it. When you look at 2 contours, one will have a higher corresponding elevation. As you go from the lower elevation to the higher elevation, you know that the land is increasing in the direction toward the higher elevation. From the higher to the lower elevation, the land is decreasing (sloping downward, decreasing in elevation).
Do Equal points of elevation on a topographic map are connected by contour lines?
A contour lines connects points of equal elevation.
Contour plowing and terracing?
Contour plowing is the farming practice of plowing across a slope following its elevation contour lines. On sloped land, contour plowing is done such that rows are side by side but each row follows a path such that every point on it is at the same elevation. So, for example, to plow a round hillock you would plow concentric circles around the hill top to bottom. The resultant furrow lines look just like the contour lines on a contour map. With this plowing method the rows hold water instead of draining it downward and becoming eroded.
Why is a contour line a type of isogram?
b
What is every fifth contour line?
it is a contour line of elevation Control index contour, or just index contour
What is the 5th contour line called?
An Index Contour
What are the difference's between contour interval and index contour?
A contour interval is the vertical distance between contour lines on a topographic map, representing the change in elevation. An index contour is a heavier contour line that is labeled with the elevation value, to help users quickly identify key elevations on the map.
How does index contour lines differ from other contour lines?
Index contour lines are thicker and usually have their elevation labeled. They help users quickly identify key elevations on a topographic map. In contrast, regular contour lines show the shape and elevation of the land but do not have specific labels.
What is the difference between and index contour and a regular contour line?
An index contour is a thicker contour line that is labeled with the elevation of that contour. It usually appears every fifth contour line and helps to quickly identify elevation changes on a topographic map. Regular contour lines are thinner and connect points of equal elevation.
What is a darker contour line usually every fifth line?
It makes it easier to count the number of contour lines.
What is the difference between a contour interval and an index contour?
A contour interval is the vertical distance between two contour lines on a map, representing the change in elevation. An index contour is a thicker contour line labeled with the elevation of the line above sea level, typically every fifth contour line. It helps users quickly identify elevation values on a map.
What do the numbers on index contour lines indicate?
The numbers of contour lines indicate altitude or elevation along that line.
How do contour lines show elevation?
The darker contour lines on map are called index contour lines. Numbers that indicate elevations are often written on these lines.
How far apart would two successive index contours be on a map with a contour interval of 5 meters?
Two successive index contours would be 10 meters apart on a map with a contour interval of 5 meters. This means that each index contour line represents a change in elevation of 10 meters from the next adjacent line.
How can index contours be identified?
Index contours on a topographic map can be identified by looking for thicker contour lines compared to the surrounding lines. They are typically labeled with their elevation value. Index contours are used to provide a quick reference to the elevation changes on the map.
The heaviest contour lines on a topographic map are?
The heaviest contour lines on a topographic map indicate the highest elevation on the map. These lines represent the peaks of mountains, hills, or other elevated land features.
