PPT-Contour Lines

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. A line that creates boundaries that separates one area from another. They define the edges and surface ridges of objects and figures.. . Contour line drawings are like coloring book pages. No Value (light and dark shadows and highlights). What is a contour . interval?. The difference . in elevation between two contour lines that are side by side.. Sometimes the map tells you! . How can we determine the contour interval?. How can we determine the contour interval?. 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.. A . map . showing the surface features of an area. Topography is based on an area’s elevation, relief, and landforms. What is topographic map?. Example:. Contour lines. Contour intervals. Reliefs. How to read . Visual Art I. FCHS. Unit #3 Line. I Can…. Identify and draw a variety of descriptive lines (outlines, contour lines, and hatching).. Identify and explain how artists use implied lines.. Perceive and discuss how lines can be expressive.. Similar to Postal and Hitchman (1999). w. = 2556 km . p . =12,823 km . A. rea. . = 8,569,380 km. 2. .

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. 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. Let’s make a topographic profile from A to C, passing through the top of the bank at B. It will help us see how steep the East Flower Garden Bank is along that line. To make a topographic profile you will need:. 1. Attendance / seating chart. Say hi to MR. . BEAN : ). Notes on Density . Worksheet. Begin Lab if time??. Lat. /Long. Time Zones. Contour maps.
