Explain the concept of overlay analysis in ArcGIS.

• Overlay analysis in ArcGIS does not combine layers, it just displays them on top of each other.

• Overlay analysis in ArcGIS only works with one layer at a time.

• Overlay analysis in ArcGIS combines multiple layers to create a new layer with retained attributes and geometry.

• Overlay analysis in ArcGIS is used to delete all attributes and geometry from the layers.
