sorry i have 2 more questions:
what happens when a contour line crosses a river:
stays flat, bends upstream , stops
why do contour lines never cross eachother:
they each represent a different elevation, the map would be too confusing, you cant tell the shape of the land
please help, these are my last questions

Your answer for the second question is correct.
No problem! I'm here to help.
When a contour line crosses a river, it usually bends upstream. This happens because contour lines are used to represent points of equal elevation, and rivers generally flow downstream. As the contour line intersects the river, it tends to bend or curve in the direction opposite to the river flow. This is because the elevation on the contour line needs to stay the same on both sides of the river.
Regarding your second question, contour lines never cross each other. The reason behind this is that each contour line represents a different elevation on a map. If contour lines were to cross, it would create confusion and make it difficult to determine the shape of the land. By keeping the contour lines separate and distinct, we can visually understand the topography more easily. Each contour line is like a horizontal slice of the land, representing a specific elevation. If two contour lines were to cross, it would imply that the land has two different elevations at that particular point, which is not possible.
