Where there is no soil for plants and trees to grow in, they become very creative. Even the smallest crack or opening allows it to send roots in to act as an anchor. Slowly the roots expand, and helped by water and ice, they enlarge the cracks sufficient to provide an area with sufficient soil, nutrients and moisture for them to survive, and grow to a normal height. The roots are capable of producing immense pressures some as much as 750 pounds per square inch. This is about 10-20 times the water pressure in most domestic water supplies, and is more than ample to allow the roots to make their way down into the water tables deep in the rock.
