Question
Please help!!!!!!!
1. What is the highest point (elevation) on this map?
2. What is the contour interval of this map?
3. What direction is Georgie Creek flowing?
4. Relief is a change in elevation. It is calculated by finding the highest point and the lowest of the area you are studying. Subtract the lowest elevation from the highest to calculate the relief. What is the total relief shown on this map?
5. Gradient is a value for the steepness of a hill, or how much vertical distance changes over a horizontal distance. It is calculated by dividing the relief of an area (elevation change) by the horizontal distance. What is the gradient of the hill at point A between 0 and 670 feet? First, draw a straight line using a ruler from 670 feet through the letter A to the Lizzy River (~0 feet). Then, calculate the relief along this line. The next step is finding the horizontal distance. Using a ruler, measure the distance along the line you drew and use the graphical scale on the map to determine the distance in miles. Then divide the relief by the horizontal distance. Express the value in units of feet per mile.
6. What is the gradient of the hill at point A between 300 and 670 feet? For this calculation, you will use the same line, but online calculate relief and measure horizontal distance along that line between 300 and 670 feet elevations.
7. What is the gradient of Georgie Creek?
8. What is the gradient of Lizzy River?
9. Which is experiencing more downcutting and erosion, Georgie Creek or Lizzy River?

670 670 Cree Georgi 100 Miles 0.5 1.0 1.5 2.0Explanation / Answer
1) 670 miles
2) The contour interval is of 50 miles.
3) It is flowing towards the South , South-West
4) Relief = Highest elevation = lowest elevation
=670-50
=620 miles.
