The four types of Constructive forces are :
*Volcanic Activity
*Deposition
*Folding
*Faulting

Another example that is commonly talked about is Alluvial Fan . An alluvial fan is a fan-shaped mass of alluvium deposited as the flow of a river decreases in velocity. The force that occurs is Deposition.
