1. What is the EXACT DISTANCE IN MILES between the cities of Watertown and Old Forge?

2. GRADIENT describes how steep or flat.
0 ft
10 ft
20 ft
20 foot elevation change
.5 mile distance

3. Gradient = change in field value / distance
0 ft
10 ft
20 ft
.5 mile distance
Gradient = change in field value / distance
Gradient = 20 feet / 0.5 mile
Gradient = 40 feet / mile

4. 0.16 oF/Mi 50 Miles separate Watertown and Old Forge.
What is the temperature gradient if Watertown is 40o F and Old Forge is 32o F?
Gradient = change in field value/distance = 8 oF/50 Mi =
0.16 oF/Mi

5. Gradients are calculated for many things, like:
The slope (or incline) of a hill.
The temperature gradient between two states.
The snowfall gradient between two cities.
Same day in Minneapolis and Miami

6. Gradient = change in field value/distance = 22 m/220Km =
What is the gradient between two points on a map that are 220 Km apart and have an elevation difference of 22 m?
Gradient = change in field value/distance = 22 m/220Km =
0.1 m/Km

7. Gr. = ch. f. v./dis. = 43.4in – 6.2in/210mi = 37.2 in/210mi
Hurricane Harvey dropped 6.2 in. of rain on Corpus Christi, TX and 43.4 in. on Houston, TX in August   
If the cities are 210 miles apart, what was the rainfall gradient between them.
Gr. = ch. f. v./dis. = 43.4in – 6.2in/210mi = 37.2 in/210mi
0.177 in/mi

10. Create missing 60 & 70 m contour lines…
Which direction does Stone River flow?
Calculate the gradient between Points A & B. 60 70

11. Distance = 0.8 Km Create missing 60 & 70 m contour lines…
Which direction does Stone River flow?
Calculate the gradient between Points A & B. 60 70
Distance = 0.8 Km

12. Change = 20 m Create missing 60 & 70 m contour lines…
Which direction does Stone River flow?
Calculate the gradient between Points A & B. 60 70
Change = 20 m

13. Gr. = ch. f. v./dis.
= 20 m/0.8 Km
= 25 m/Km 60 70
