How do rocks split to make a waterfall?
Question Date: 2013-02-27
Answer 1:

Rocks don't so much split to make a waterfall - rather, water carves the chasm as it falls. Now, you need mountains or some other way to get the difference in height so that water can do this, and for that you need faults and earthquakes, but waterfalls themselves are made by the water of the fall.
