How do contuor lines help you to determine the area of an island has the steepest slope?
The area with the steepest slope is the area where the contour lines are bunched closest together.
Do closely spaced contour lines indicate a steep slope?
A contour line (also known as isopleth) on a topographic map connects points of equal elevation or depth. The steepest way up or down is in the direction perpendicular to the contour line at any given point. This gradient on a topographic map is at its greatest when the lines are close together, thus the slope is steepest. Note that a contour map does not have to be topographic. Any value mapped in two or three dimensions such as temperature, barometric pressure, or wind speed can have contour lines connecting adjacent points of equal value. Again, moving away from a contour line in a perpendicular direction will yield the greatest change in the value of the quality being recorded.
What are depression contour lines called?
The lines for depression are called hachured lines
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 is the difference called between two side by side contour lines?
the contour interval
How do contuor lines help you to determine the area of an island has the steepest slope?
The area with the steepest slope is the area where the contour lines are bunched closest together.
Which area of this map has the steepest slope?
To determine which area of the map has the steepest slope, look for regions where the contour lines are closest together. Steeper slopes are indicated by these closely spaced contour lines, while flatter areas have lines that are further apart. Additionally, consider any elevation changes in relation to the distance between contours to identify the steepest section accurately.
How could you find the steepest slope by looking at contour lines?
each contour line represents an equal value, so the closer the lines the steeper the slope
What area of this map has the steepest slope?
The area with the steepest slope on a map is typically where the contour lines are closest together, indicating a rapid change in elevation over a short distance. Look for areas where the contour lines are tightly spaced or where the lines bend sharply, as this suggests a steep slope.
What do hachures on a contour indicate?
Hachure lines are a form of representation for showing the contours on a map. They point towards the steepest part of the slope. Hachure lines are an old form of showing relief, and less useful, scientifically, than contour lines.
What On topographic maps contour lines that are close together indicates?
The steeper the slope, the contour lines go further along the area. You can also determine the flatness of the area with these lines.
Which side of the land on the map is steepest. A.North side B.East side C.West side D.South side?
Maps don't work like that. The steepest land could be anywhere. You must view the contour lines and follow them to find what is steep or not.

What is the difference between any two contour lines on a map?
Contour lines on a map represent points of equal elevation. The difference in elevation between any two contour lines is called the contour interval, which is usually indicated on the map legend. By knowing the contour interval, you can determine the steepness of the terrain in that specific area.
How do you determine the elevation of unlabled contour lines?
The distance in height between contour lines should be stated in the map's legend. If the contours are stated in the legend as being 50 metres apart, then count the lines upwards from a contour that has a height against it, and multiply by the number of unlabelled lines.
How would you show an island in the ocean with the elevation of 80 feet if the contour interval is 10 feet?
To show an island with an elevation of 80 feet on a map with a contour interval of 10 feet, you would need to represent two contour lines: one at 80 feet and another at 90 feet. The space between the lines would then indicate the slope of the island's terrain.
What is the value of the angle of intersection of a contour and a ridge line?
The angle of intersection between a contour line and a ridge line typically measures 90 degrees. This is because contour lines represent points of equal elevation, while ridge lines indicate the highest points in a terrain. At the intersection, the contour line is perpendicular to the direction of the steepest ascent or descent, which is represented by the ridge line. Therefore, the angle of intersection is generally a right angle.
