On the global scale, hotspots vary gravimetrically and in their elevation and magnetic properties. Some hotspots may have shallow origins and some may be from deeper mantle plumes. I investigate these for insight on what makes up hotspots and their subsurface attributes. I model the mantle plume geometry to help define their gravity signals. By comparing the observed and simulated gravity signals, we can constrain the geometry of the subsurface. Scale modeling with soaps can help us visualize the analogous dynamics of mantle plumes due to the related subsurface.
