Q: What do contour lines that are close together indicate?


Read this paragraph and choose the correct option from the provided answers:

1. The spacing of contour lines shows the slope of the land . Contour lines that are close together indicate a steep slope. This is because the elevation changes quickly in a small area. Contour lines that seem to touch indicate a very steep slope, like a cliff. When contour lines are spaced far apart, the slope is gentle. So contour lines help us see the three-dimensional shape of the land.

 Choices:

- deep slope

- close slope

- flat slope

- steep slope


A:
steep slope
