PPT-This is a topographic contour base map we will use to explore structure contours and the

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 doesnt parallel contours we know it isnt horizontal and given that it doesnt cut straight across contours we know it isnt vertical Can we tell something about its orientation . Sharma. CONTOURING. by:-. Contour. . An imaginary line on the ground surface joining the points of equal elevation is known as contour. . In other words, contour is a . line. in which the ground surface is intersected by a level surface obtained by joining points of . 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. Can we tell something about its orientation? . 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.. Take notes in your science notebook.. Label your map.. Map Notes. topography. The study…. The study of the shapes and features of the Earth’s surface.. Topography. Shows the three dimensional shape and elevations of an area of land in two dimensions. Topography. Shows the three dimensional shape and elevations of an area of land in two dimensions. Topographic Map. Height above sea level. Elevation. Line that connects places on a topographic map that are all at the same elevation (eventually a closed loop). Contour lines never cross or touch!. Mapping Mechanics: . An introduction to topography . by the use of contour lines . Upon completion of this lesson, students will be able to:. define topography. define the USGS and different techniques used to study topography. Contour lines are lines drawn on a map that connect points of equal elevation. If you walk along a contour line you neither gain or lose elevation.  . Picture walking along a beach exactly where the water. 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. the following. :. Match your . cards.. Take notes in your science . notebook.. Label your . map.. Map Notes. topography. The study…. The . study of the shapes and features of the Earth’s surface.. Using Contour Maps. What is a Topographic Map?. Earth's surface shape shown by . contour lines. Contour lines. - lines connecting points of equal elevation. measure mountain height, ocean depths, slope steepness. 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?. Outline. Contour drawing in art. S. il. h. o. uette. . / outline. Definition of outlines.
