Fault-block mountains are formed by extensional stresses.
Explanation:
- Fault-block mountains are formed because of extensional stresses. They are also called tension stresses.
- These stresses pulls and stretches rocks apart which causes normal faults to form.
- The normal fault cuts through rocks, causing one to slip downward and one to move upward. Thus, fault-block mountains are formed.
- Sierra Nevada in California and Nevada is an example of a fault-block mountain.

I am answering under the assumption that those are cacti in the desert. Well as we know, cacti are producers they have the ability to synthesize their own food using photosynthesis which is a process that converts solar energy into glucose “food”. It has the ability to be a good source to small animals with its fruits and seeds. An example is, some insects feed off the nectar from the cacti. A second reason is that cacti are carbon sinks meaning that they take in carbon dioxide. Just to familiarize you the formula for photosynthesis is CO2 + H2O + energy equals glucose + O2 . Without carbon dioxide none of it is possible. Without cacti, CO2 levels would increase leading to bad affects.
