because it is hard to see
Because Earth is very very large and we live just on the very surface.
The structure of a nephron is difficult to determine because a nephron is very small, and there are so many nephrons piled on top of each other that they are difficult to distinguish. A healthy human kidney has about 1 million nephrons.

Geology
physical structure is geology and geology is a movement in the earths crust which is also physical structure.
Scientists use seismic waves from earthquakes to study the Earth's interior. By analyzing how these waves travel through the layers of the Earth, they can determine the composition and structure of the planet without physically reaching the core.
how does size determine structure in organizational design?
It is difficult to determine Earth's inner structure because we cannot directly observe what lies beneath the surface. Most of our information comes from indirect methods like studying seismic waves, which can provide insights into the layers of the Earth. Additionally, extreme heat, pressure, and the lack of access to deep layers make it challenging to explore and study Earth's interior.
