lines represent lines connecting points of equal elevation above sea level, Contour lines never cross, split, or die off, Contour intervals must be obeyed, therefore the contour lineelevations can only be multiples of the contour interval. Zoom out and examine the surrounding area, what geological hazards are likely in the area? What is the change in elevation across each contour interval (i.e., between successive "regular" contours) on this map? How fast was the Pacific plate moving from 7.2 million years ago to 4.7 million years ago between the formation of Kauai and Nihoa in cm/year? How are the tops of hills, mountains or depressions (dips) shown on a topographic map? What is the latitude for the southeast corner of the map?

Because there isnt a 60ft contour line on this hilltop, we know that the hills highest point (the crest) is some elevation between 50 and 60ft. A. Topographic
Hint: draw a simple map or a rough cross-section sketch to help illustrate your logic. than 6760 feet, but less than 6800 feet. Likewise the "40" contour connects depths of 40 ft below sea level and so on. Each contour line shows a different elevation. - Table 8 . For the following exercises, please refer to British Columbia Topographic Map 092G095 of the Mount Garibaldi area in southern BC. A standard topographic map uses contour linesto express elevations above sea level and show the shape of the land. First Edition. Show your work below. Join TheConstructor to ask questions, answer questions, write articles, and connect with other people. 31W. Contour lines Lines or isolines on a map that connect points with the same elevation. To keep the contour map simple and easy to read, not every contour line is marked with its elevation reading. Locations A and B are at the same elevation. Location A is higher. Your contour lines will generally fall between the GPS points on your map, so you will need to estimate many of the contour line positions. Set up the cancellation table so all units will cancel, except the desired unit, feet. How far did the pole move in meters in one year during this time period? It is determined as follows: Let's take an example of two contour lines which are labelled. Do Pole movements seem to be steady every 100 years or variable? The contour music definition is the same definition in any medium such as visual art,. Vertical exaggeration is the effect that is created when the horizontal and
Overview section 7.3 provides background information on contour lines to prepare you for these exercises. To determine the elevation of a point on a topographic map: The highest point of the rim of the crater is about 350. Terms and conditions apply. Sharp contour points indicate pointed ridges. which isotopic system should they use. 3. Figure 4: Reading Contour Maps . What important discovery did the researcher miss? lowest line (which is 6760 feet, and not marked) has an elevation equal or greater
Contour lines do not cross each other, divide or split. Measure the distance using the bar scale between the pole 1400 and 1700 (locations C and F). On a topographic map, a contour line is a line that depicts ground elevation or depression. Mark
Contour
In Figure 9.4, what is the elevation of the highest point on Hunt Ridge (keep in mind step #4 from the first question)? CONTOUR/SPACING= Sets spacing for contour labels; default spacing is 5". "Contour" actually means "outline" in French, which is where the name comes from. The highest point on a topographic map is marked as 345m. Every sixth contour line has an index contour, which is a bolder or thicker line. 10. 2. Note: if you are unable to read the contours on the map, view the original map on the web or look at the large printed copy in the lab. Question 14. dimensional space. Pick two contour lines that are next to each other and find the difference in associated numbers. The contour interval (height difference from one contour line to the next) on the 500 mb height map shown above is 3 decameters (abbreviated as 3 dam) or 30 meters (abbreviated as 30 m). Usually there are different contour intervals for the different maps. Comparable to figure 8 D-F in ref.

To calculate the vertical exaggeration in the topographic profile shown in Figure 3.6 we divide the horizontal scale by the vertical scale: (\(\frac{\frac{1000\;ft}{1\;inch})}{(\frac{100\;ft}{inch}}) = 10\). Therefore: Rise = change in elevation = top (Point A elevation) minus bottom (Point B . Show that the streamlines of \nabla \varphi are orthogonal to the level surfaces of \varphi. Answers: 1 Show answers Another question on Biology. 750m. In every map, on the right-hand bottom side, the contour interval is described. You can figure out the elevation of
A slope is easy to recognize in a hilly area. Essentially a topographic profile is a side image of a topographic map, but the image is only a representation of the area shown on the line on the topographic map (line A-B on Figure 3.6). S waves cant travel through liquids and this depth is where the liquid outer core exists. which means that every place between the marked 6800 foot line and the next
For all of the following figures, assume north is at the top of the map, and south at the bottom. Write your answer in feet. Index contours are bold or thicker lines that appear at every fifth contour line. elevation of each index contour line. They also show elevation. The elevation at sea level is zero meters. TAs names: _______________ _______________. The intersection between the landscape and the horizontal paper marks the location of the contour lines on a two-dimensional map. in the southern portion of the map, the area is underlain by limestone. Intervals involvinq the tonal centre, and their directions of movement -1 1 0 0 0 -1 0 1 0 0 -9 0 0 0 -8 1 0 0 -7 0 0 0 -6 .

Examine the map below to answer the question. Both A and B (20-2900 Km and 2900-5100 Km). When the vertical dimension of your graph is different from the horizontal dimension on your map, you may end up with a graph that shows a vertical exaggerationand the features of the Earth represented by your topographic profile may be deformed such as in Figure 3.7. What happens when the lithosphere at point X is heated to 1500 C? A higher contour interval is used for a large area and small contour interval for small area. Using a contour interval of 40 m, label the elevation of every contour line on the map below. Contour lines rules: 1. It is thought to have formed by the runoff of either precipitation or groundwater. The river in this area has a rather particular pattern, what geologic process caused this? Location A is higher. According to the geothermal gradient, rocks buried 75 km beneath the surface would normally be at what temperature? The following are general
