How do I merge data in ArcMap?
Q: How do I merge two or more layers in ArcGIS?

What is raster overlay?
Raster overlay involves two or more different sets of data that derive from a common grid. The separate sets of data are usually given numerical values. These values then are mathematically merged together to create a new set of values for a single output layer.
What is raster clipping?
This tool allows you to extract a portion of a raster dataset based on a template extent. The clip output includes any pixels that intersect the template extent. To extract a portion of a feature dataset, use the Clip tool in the Analysis toolbox.
Where is the merge tool in ArcMap?
Data Management Toolbox
In ArcGIS and ArcGIS Pro, the Merge Tool is in the Data Management Toolbox and within the General Toolset. You can add your inputs and change your output feature class name. The field map option is to match all the corresponding fields, so they’ll be combined together after running the Merge Tool.

In other words, the boundaries of the second polygon are imposed on the first polygon.
Can you clip a raster ArcMap?
An existing raster or vector layer can be used as the clip extent. If you are using a feature class as the output extent, you have the option to clip the raster by the minimum bounding rectangle of the feature class or by the polygon geometry of the features.
