Final answer:
Upwarped mountains are formed by the uplifting forces within the Earth's crust, hence the statement is true.
Step-by-step explanation:
The answer to Question 7992 is A. True. Upwarped mountains are indeed formed when forces inside the Earth push the crust upward. This can occur as a result of tectonic forces such as the movement of the Earth's plates and volcanic activity.
For example, the uplift of large areas of the crust leads to the creation of mountain ranges. The process is also evident in areas like Death Valley, where compressional forces have caused folds, warps, and fractures in the crust. Additionally, after being formed, these mountain ranges undergo erosion which further shapes the landscape.
