Answer:
By the information given, I am not sure how the event has played out. However, using common knowledge, I can give a scenario of how it may play out.
When removing the first block (the foundation), gravity will pull the other blocks down, as the strength of gravity exceeds that of the strength of air holding it up. This means that all the blocks on top would fall.
By definition of Newton's 1st - 3rd laws, the blocks would not move unless a force is given to it (i.e., removing the bottom block, which causes gravity). Gravity would pull the other blocks downwards. This would lead to the falling of the stack of blocks.

Answer:
Explanation:
A stack of blocks sits in equilibrium. That means, by Newton's 1st law, all blocks will remain stationary. The weight of each block is balanced by the reaction force from the block underneath it. The bottom block experiences a reaction force equals to the total weight of all blocks from the ground.
When the bottom block is removed, there will not be any reaction force from the ground. That causes a disturbance in the equilibrium. Without the balancing reaction, the blocks will have the gravity force from their weights pulling them down. By Newton 2nd law, the unbalance force will cause the blocks to accelerate towards the ground until they all crash-land.
DISTANCE
-length of the path between two points
-doesn't have to be a straight path
-has no direction
DISPLACEMENT
-the length from the starting point to the ending point
-must be a straight path
-must have direction (north, south, east, west, up, down)
EXAMPLE-If you wanted to know the distance from your house to the park, you could say 'three blocks north and then two blocks west' but for displacement, you could just cut through houses and backyards to get to the destination.
Hope that makes some sense :)
