What's the difference between a topographic map and a regular map?. Topographic Maps. Contouring. Topographic contours indicating surface relief. Image taken from US Army training manual.. Solid yellow lines represent surface isobars, line of equal air pressure. Green dashed lines are geopotential heights, the altitude at which 500 millibars of air pressure are attained. These types of contour maps are used by meteorologists. The weather system shown is the Storm of the Century, a powerful winter storm called a nor’easter.. Match your cards..

Upon completion of this lesson, students will be able to:. define topography. define the USGS and different techniques used to study topography. Maps. Topographic Map. :. A . contour map. -. Complicated Topographic Map. Simple Topographic Map. I am standing where the land meets the water, what is this called?. *All elevations are relative to sea level. Topographic notes. Topographic Map-includes contour lines drawn to represent changes in elevation.. Topographic maps take 3 dimensional ups and downs of the terrain and show them on 2 dimensional surface.. Aim: To be able to interpret a topographic Map.. What is a Topographic Map?. A topographic map. shows surface features,. or topography, of the . Earth. . Topography can be natural or human-made. interpret topographic maps and satellite views to identify land and erosional features and predict how these features may be reshaped by weathering. A 2D view of a 3D surface. How. do topographic maps give you a picture of what the landscape looks like?. a ridge. a valley. g. oing uphill. closer . contours. = steeper slope. contours farther apart = shallower slope. Imagine that the red line represents a geologic contact of some sort. Given that it doesn’t parallel contours we know it isn’t horizontal, and given that it doesn’t cut straight across contours we know it isn’t vertical.
