Step-by-step explanation:
Geological activity determines geological structures. The prevalent types and forms of tectonic working in a place will control the form of structure that can be found in a terrain.
- In volcanic region, it is common to see volcanic structures of different types such as calderas, strato-volcano etc. These structures are formed by the volcanic activities.
- Also, in a karst topography, we find sink holes, stalactites and stalagmites etc. due to the nature of the geologic activities going on.
- Some sedimentary rocks shows cross bedding due to the environment where they form.
So, geologic activities controls the structure found in an area
