Answer:
Within Internal Geodynamics, geophysics is the one that studies the dynamics of the processes that have given rise to the structure of the Earth.
Explanation:
Geodynamics is the analysis of the changes that occur in the crust of planet Earth. This study is developed in the framework of geology.
It is possible to distinguish between external geodynamics (which refers to the exogenous processes of the earth's crust) and internal geodynamics (linked to endogenous processes).
The development of internal geodynamics is supported by a series of techniques called geophysics. The science known as geophysics is that which focuses on the observation of the Earth taking into account the principles of physics to study the phenomena that are linked to its evolutionary history, its structure and its physical conditions.
For the development of its studies, geophysics uses various quantitative methods, measuring electromagnetic fields, radiation and gravity, for example.
