Contour lines determine the steepness of the land by how close they are together. Generally, contour lines rise to a particular scale (e.g. a line for every ten metres), therefore, if the contour lines are closer together then the height of that particular area has risen more steeply than if the contour lines are further apart where the steepness has increased more gradually.
It causes for the world climate to rise causing global warming. Also erosion causes be buildings to be eaten away from water or acid rain and can destroy homes and possible hurt humans. Deposition runs into the water and streams with eventually goes to the water lines to the food and drinks we consume today.
