Which region of Earth’s crust experiences the least amount of pressure? crust mantle outer core inner core
Ne4ueva [31]

The correct answer is the crust.  

The crust is present above the mantle and is the hard outer shell of the Earth. The crust is 0 to 32 km in thickness. The densest type of crust is oceanic crust with the density of 3.0 g/cm3. The mantle is the layer below the crust and above the core.  

The mantle exhibits an average density of 4.5 g/cm3. The density increases with depth as the pressure increases. The outer core exhibits a density between the range of 10 g/cm3 to 12.3 g per cm3 and the density of the inner core is about 12 g/cm3. Showing that the inner core exhibits the highest pressure.

How might a theory relate to a model
DaniilM [7]
Theory relates to a model in science because it presents the possible paradigms and patterns of the said concept and fact. It explains and elaborates the phenomenon of why it happened, how it happened and the factors that are involved in the process. A theory is a possible explanation of certain occurrence. 

In addition, any time a scientific theory is challenged, it means it's not a good theory. And this statement is not valid. In theoretical models, they are revisited when there are further studies and discoveries found in a certain area where they can be remodeled and reintegrated instead of disregarding its credibility. Models, theories, and paradigms are not challenged but rather encouraged, they are supported in many studies since these theories and models were created in order for us to understand a certain phenomenon but it would likely help the scientific society to be updated in the new forms or spheres of improvement rather than discouragement.  <span> </span>
