The Intersect Tool in GIS performs a geometric overlap. All features and attributes that overlap will become part of the output feature class.
The Append Tool adds data from one or more sources of data and puts it into an existing target dataset, without creating a new dataset.
The Erase Tool removes the area that is overlapping with the erasing features. Everything outside the erasing layer ends up in the output.
