Here is a sentence from a game app's description:
In the game, you soar off ramps to beat competitors to the finish line.
I am not sure about the meaning of the phrase soar off ramps here. How would you explain the same idea in different words?
The meaning seems to be literal. For example, think of ski jumping:
In this picture, the skier is soaring off a ramp. "Soaring" is essentially synonymous with "gliding"; the skier will be in the air for at least a second and travel quite some distance. "Off" tells us that the skier used the ramp to help her jump. A "ramp" is essentially a slope; in this image it is the large structure in the background, but other sports use ramps that look different.
