What are depression contour lines called?
The lines for depression are called hachured lines
What are lines connecting points of equal height called?
Contour 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 elevation between one contour line and the next one on a map?
It depends completely on the type of map and the scale of the map. Look several contour lines above and below the area of interest. Often, the elevation is printed on every 5th contour line. Divide the difference by the number of spaces between the two lines. Example, one contour line says "1000" and the next one with an elevation says "1500". If there are 4 lines in between these two, it is 100 ft per contour line. In some areas, you will need to follow a contour line around the map to track down the elevation of that line. Easier still, check the legend on the side or bottom of the map. The example showing the colors or symbols used may also tell the contour interval if it is consistent for the entire map.
How do contour lines determine which area of an island has the steepest slope?
The closer the contour lines the steeper the slope.
