Topographic maps are used to measure the elevation.

Explanation:

A topographic map is a two-dimensional representation of an area or a region in which the differences in the elevation of the terrain are shown with the help of contour lines. These contour lines pass through points of the same elevation giving a brief idea of the geographical undulations and features in the region. Topographic maps are generally used for geological mapping of different terrains.

This is what i found “getting into the technicalities, the continental crust has a density of around 3.0 g/cm3 compared to 2.6 g/cm3 of the continental crust. in addition, the continental crust is much thicker than the oceanic crust. the recycling process does not happen to the continental layer.” i hope this you for what your looking for. can you plz mark me brainliest?
