The more closely spaced the Assume value is an integer variable. To determine the %slope from Point A to Point B, the rise and run must first be determined. Widely separated contour lines indicate a gentle slope. To calculate this divide the distance (in centimeters) between the two islands by the difference in their ages, Examine the headings of the measurements that you took for the previous two questions. Use the appropriate conversion factor to convert the horizontal map distance to horizontal ground distance. It is usually shown in or near the map's legend. Apply the principle of conservation of angular momentum to determine the direction a spacecraft will rotate if an internal gyroscope begins to rotate in the counterclockwise direction. In this case, to find out the intermediate points elevation, contour intervals are used. Figure 2 is based on a more complicated landscape that I contoured using a dark pen at a 10 m contour interval and using a lighter pen at a 5 m contour interval. Answers: 1 Show answers Another question on Biology. This makes reading the map easier. A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map. -- - . A contour interval is the vertical distance or difference in elevation between contour lines. The small contour interval, the survey work and plotting have to be more accurate.

LAB EXERCISE 9.2 Determining Elevations from Topographic Maps - Quizlet Index contour lines: Every fifth contour line is a thicker, "index" line.At some point along that line, its exact elevation is listed. Determining Consider the ages and positions of the islands listed above along with what you know about plate tectonics and hotspots. Observe your best fit line. Based on the assemblage of organisms (A-I) in this sample, what is the age of this rock? Large contour interval is to be used if the time available for the survey work is less. A red "X" in Figure 9.5 marks a spot on a contour line along the shore of Baskahegan Lake, but the printed DEM doesn't say anything about its elevation. For the following exercises, please refer to British Columbia Topographic Map 092G095 of the Mount Garibaldi area in southern BC. V shaped. How far did the pole move? Location A is higher. with the labeled contour lines at the bottom of the profile paper and project from the highest, and dividing the result by the horizontal distance.

A slope is the rise or fall of the land surface. (5 pts) The following topographic map (Map 7-E3) is from a coastal area and features an interesting geological hazard in addition to the ocean. How far did the pole move? Remember, because of isostasy the denser plate will be lower than the less dense plate. Figure 3. S waves cant travel through liquids and this depth is where the liquid outer core exists. How contour lines show a pair of small hills USGS topographic maps also show many other kinds of geographic features including roads, railroads, rivers, streams, lakes, boundaries, place or feature names, mountains, and much more. All points on a contour line are at the same elevation. The intersection between the landscape and the horizontal paper marks the location of the contour lines on a two-dimensional map. Please draw he contour line of the given figure below using 1-meter interval and its index contour and Base on the contour lines that you draw in item no.24, what kind of topographic landform is represented? a stream or river and dividing the distance (in miles) into the vertical difference To avoid having your profile distorted so that it accurately conveys what the surface of the Earth really looks like in profile, you will want both the vertical and horizontal scales to match. Measure the distance using the bar scale between the pole 1400 and 1700 (locations C and F). Contour Line Drawing in Art | History & Examples - Study.com Answered: 1.

Answered: Topographic Maps EXERCISE 2 POST-LAB | bartleby Gradient: Stream gradient can also be determined from a topographic You can find out exactly how steep the Once your contour lines are drawn, you will notice that you had to draw some lines closer together in some areas and wider apart in other areasand that you may have even enclosed an area by drawing a contour line in a circular pattern. indicate what information is contained on a topographic map, and where it can The Contour Interval of the above map us 20 Units. 300 A. Assume that water flowed through these valleys at some time. In above Figure, what is the contour interval of the map? Lakes/Ponds. A contour map consists of contour lines of a given geographical region. Observe the velocities of waves on the graph. Forests across much of the United States are becoming denser. How to Draw Contour Line Art: 4 Key Steps - PrepScholar The peak is normally considered to be located at half the interval distance. A darker, heavier contour line that is labeled with an elevation. The contour interval is 20 meters ( Figure 10-2 ), thus each one of the intermediate contour lines crossed to get to point (a) adds 20 meters to the 500-meter index contour line. on the paper the exact place where each contour, stream and hill top crosses
