What is the difference between a contour interval and an index contour?
the contour interval is the difference in elevation between contour lines that are next to each other
Why can't two contour lines overlap?
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
The change in elevation from one contour line to the next is called what?
The change in the elevation between isolines is called a contour line. Contour lines on a topographical map resemble a volcano.
Do contour lines always need to be joined?
Yes, but more than one line may be joined onto another Yes, but more than one contour line may join onto another in the case of a cliff face or other steep slope
Why do you think one contour line never crosses another contour line?
Each contour line represents a different elevation. If two contour lines crossed, or touched, then the point where they cross or touch would be a point that has two different elevations, which would be pretty silly.

What is the elevation change between two adjacent lines on the map?
Those lines representing elevation on a map are called contour lines. The difference in elevation between two of these lines is called the contour interval. Different maps use different contour intervals based on the scale of the map, or in other words, the size of the contour interval is based on how zoomed in and detailed the map is. Sometimes a map will have darker and thicker contour intervals. This is called the Index Contour Interval. Index contour intervals appear less frequently and represent a larger elevation change. It helps you figure out the amount of a large elevation difference faster because usually they are multiples of 100 or 1000, making them easier to add up.

How Do Topographic Maps Differ From Relief Maps?
On a topographic map, elevation is represented by countour lines, which is two lines that connect without intersecting. Relief is also shown by contour lines but also with a variety of other methods, such as shades and colors.
Why can't two contour lines overlap?
One contour can not cross another because a contour is one exact elevation; if it crossed another contour it would show that it is higher than the second contour on one side, but lower on the other side.
Very tight contour lines is?
The closer the lines to each other the steeper the slope.
How must contour lines bend to indicate a stream valley?
contour lines bend in a V shape pointing uphill because it flows the other direction
What are two things that contour lines cannot do?
Contour lines can never touch each other, and they can never just stop, they have tonot go off the page or connect.
How can you show height on a map other that with contour lines?
shading, numbers
How do contour lines show steep and gentle?
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.
What are the characteristics of contour?
One of the characteristics of contour is that the variation of the vertical distance between any of the two contour lines are usually assumed to be uniform. The other characteristic is that all the points on a contour line are of the same elevation.
