It is the logical path down for water. If you are on a slope and drop a ball, it should follow the "fall line" downward. The phrase is very familiar to skiers.
Correct! The fall line is a geological feature that refers to a boundary in an area where the land transitions from an area of relatively flat terrain to a steeper slope. It is often associated with rivers and streams, where the water follows the natural slope of the land and creates rapids and waterfalls. The term is also used in skiing to refer to the natural path down a mountainside that follows the fall line.
The correct answer is:
a tall, steep area where rivers form rapids and waterfalls
To understand what a fall line is, imagine a river flowing from higher elevation to lower elevation. As the river encounters steeper terrain, it can create rapids and waterfalls. This transition zone between the higher and lower elevation is known as the fall line. In this case, the fall line refers to a specific geographic feature rather than a series of mountains, a raised area in the foothills, or a coastal lowland.
