Discoverable means that something can be found or learned about, while visible means that something can be seen or perceived. In other words, discoverable things are not always visible, and visible things are not always discoverable.
For example, a treasure chest buried underground is discoverable, but it is not visible. Similarly, a person's thoughts and feelings are discoverable through conversation or observation, but they are not visible.
On the other hand, a rainbow is visible, but it is not discoverable in the sense that it cannot be found or learned about. Similarly, a person's physical appearance is visible, but it does not reveal anything about their thoughts or feelings.
In general, discoverable things are more abstract and intangible than visible things. Visible things are more concrete and tangible.
Here are some other examples of discoverable and visible things:
* Discoverable: The cause of a disease, the meaning of a dream, the best way to solve a problem
* Visible: A person's face, a tree, a car
It is important to note that the distinction between discoverable and visible is not always clear-cut. There are some things that could be considered both discoverable and visible, such as a fingerprint or a footprint. In these cases, it is up to the individual to decide which term is more appropriate.
