Question
Rest assured this is not a homework question. If you think the question is so Fundamental, I do not know about the Answer, therefore, I ask the question. Does digging a hole in the soil in the backyard in a state where it rains on a regular basis causes the collection of rain water and in winter snow to cause the hole to expand?  

Answer
I volunteer my time to answer questions for people who have problems.  You don't have a problem. You have a question, which you should try to solve by experimentation and deduction. I know the answer, you know the answer. Just stop and look at the natural processes that are happening around you. Although you'll have many variables that effect the speed of the outcome, the size of the hole, the amount of wind and rain, the outcome is always the same.
