The phrase "100 feet in the air" typically refers to something elevated above the ground, while "lies on the ground" suggests it is at ground level. A playful interpretation could be that a tree or tall building stands 100 feet high, with its roots or foundation firmly on the ground. Alternatively, it could also refer to an object like a kite or balloon that is tethered and only appears to be floating above the ground.

Do a hundred crunches feet up in the air and try to touch your toes with each one. Then do a hundred more with your feet flat on the ground. Then do a hundred with each leg in the air. Then do a hundred reverse crunches which is when you lie on your back with your legs up and lift your butt off the ground. If you do this every day for a week, you should have a six pack.

Hot air balloons can travel in the troposphere, which is the lowest layer of Earth's atmosphere. They typically fly at altitudes ranging from a few hundred feet to a few thousand feet above the ground.
The ground temperature at 5 feet below the surface is typically more stable and closer to the average annual air temperature of the region.
