PROCEDURE (18pts)
- Carefully tape the clear plastic sheet to the box lid. This sheet must remain dry.
- Fill the container with water up to the second black mark (located on the side of the container). This will be the zero elevation (sea level). Trace the level of the water using the pen provided. Note: the ink is very water soluble.
- Fill the container until half way to the next higher mark. Trace the water level again
- Continue filling and tracing, increasing half a mark each time until the mountain is covered.
- Trace the completed map onto a plain piece of paper.
CONCLUSION (7pts)
GIVEN: Each black mark on the side of the container represents 200ft elevation gain.
- What is the contour interval for your map?
- What is the elevation of the mountain?
- What type of slope is represented by widely spaced contour lines, by closely spaced contour lines?
- With a different colored pen or pencil circle the areas on your map which represent valleys. Which way to the contour line point (upslope or downslope)?
- How are mountains represented by the contour lines?
- How can you represent the decrease in elevation which occurs at the top of the mountain?
