3. Calculate the temperature gradient from Point A to Point B.

4. GRADIENT is a value describing how steep or flat.
0 ft
10 ft
20 ft
20 foot elevation change
.5 mile distance

5. 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

6. 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

7. Gradient = change in field value/distance = 8 oF/50Km =
What is the EXACT DISTANCE IN KILOMETERS between the cities of Elmira and Ithaca?
50 Km
What is the temperature gradient if Elmira is 32o F and Ithaca is 40o F?
Gradient = change in field value/distance = 8 oF/50Km =
0.16 oF/Km

8. 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

9. Hurricane Harvey dropped 6
Hurricane Harvey dropped 6.2 inches of rain on Corpus Christi, TX and whopping 43.4 inches of rain on Houston, TX in August   
If the cities are 210 miles apart, what was the rainfall gradient between them.
0.177 in/mi
