PLEASE ANSWER ALL THE FOLLOWING QUESTIONS USING THE MAP ABOVE! THANK YOU FOR THE HELP!
Using a ping Topographic Map GeoLab opographic maps show two-dimensional represe of Earth's surface. With these maps, you can determine ntatio how steep a hill is, what direction streams flow, and where mines, wetlands, and other features are located.

1) contour interval is 10 feet. It is given in the scale of map.
Ex. You can see at jeep that contour is 1071 and then left to it after 1 line it shows 1050.
2) stream gradient = (high contour - low contour) /distance
Here gravel pit shows 750 feet contour, creek shows 710feet
The distance between gravel pit and creek is 2.71 mile
Therefore, (750-710)/2.71
= 14.76feet/mile
The unit of stream gradient is always feet/mile
3) highest elevation of jeep trail is 1071feet
The elevation at the unimproved road is 701 feet
Hence change in elevation is 1071feet - 701feet
= 370feet
4) measure the distance ( follow the scale given in the map)
We get 3mile
5) the distance between BM to gravel pit is 1.06 mile.
The change in elevation is 1071ft - 750ft
= 321feet
1)yes, it flows all year round because the stream gradient is very low, slope is gentle and water runoff from adjacent valley is high which means water quantity is high but speed of water is low which means water will be available for longer period.
2) shortest distance from gravel pit to secondary highway is the straight line which is 1.42 mile long.
