Causing a Problem
The sheer size of this glacier can cause a huge problem. One excellent analogy of this situation has been provided by Dr. Emma Smith, which states that the process is quite similar to how dense liquid travels across a surface.
Implementing the Analogy
Dr. Emma Smith continues by saying that you should imagine pouring a bunch of treacle on to a flat surface. After this, you should watch how this liquid flows outward. Now, pour the identical treacle on a surface with bumps and lumps. This provides a different reaction.
