- If the rate of snow falling at a geographic area during a time interval is a function quantity,
- then there exist a transfer, an object,, , a self connected object,, , an entity,, , another self connected object and another entity such that the transfer is an instance of snowing and the transfer is located at the geographic area and the time of existence of the transfer takes place during the time interval and the object is an instance of snow and the object transferred in the transfer is the object and the self connected object is an instance of board or block and the bottom of the self connected object is the other self connected object and flat is an attribute of the other self connected object and the self connected object is located at the geographic area and there doesn't exist a third entity such that the third entity is an instance of object and the third entity is located at the self connected object holds during the beginning of the time interval and the object is located at the self connected object and the top of the object is the entity and the depth from the entity to the other self connected object is the other entity and the other entity is equal to the time interval and the function quantity holds during the end of the time interval
