A Geometry object at the object level contains a geometry (SOP - Surface Operator) network inside. This network holds the geometry nodes that control the flow of geometry through the nodes, from nodes that generate new geometry through nodes that modify the geometry.
For more information, refer to the Houdini documentation for Geometry Nodes.
