Slope in the real world called Pitch and/or Grade

Question

1. Sometimes slope is called "pitch". Look on the internet for an industry that calls slope "pitch" and give an example of pitch in the real world.

2. Sometimes slope is called "grade". Look on the internet for an industry that calls slope "grade" and give an example of grade in the real world.

Answer 1

"Grade" is most often seen in situations where it refers to the slope of the ground.  A highway sign warning for a steep hill may reference a 10% grade.  You can also snoop around for home building or landscaping applications where it may be referenced as inches per foot.  A little grade is required for good drainage.
