What factors have contributed to desertification in the region? farming flooding omvs overgrazing population growth?
Answer: farming, overgrazing, population growth
Desertification is a process that occurs naturally or by human induce causes, the water body of the region gets dried up and the region acquires desert like conditions such as soil looses it's moisture and becomes compact, limited vegetation cover and dry climate.
Farming is the agricultural practice which involves the growth of commercially valuable crops. The excess use of land for agricultural purpose can result in the loss of the minerals and organic matter necessary for growth of plants. The land will loose it's fertility and will become barren land. The barren land will acquire desert like conditions.
Overgrazing can be responsible for desertification, as the herbivorous animals sometimes consume plants down the ground, which means they consume entire plant along with the roots. The soil gets loosen and eroded by wind. This way soil looses it's fertility and no more plants can be grown on such soils. This results in desertification.
Increase in population will result in increase in demand of water. This may result in depletion of water body for human use. Hence, population growth may lead to desertification.

What factor would account for a strong synovial joint? what factor would account for a strong synovial joint? small reinforcing ligaments synovial fluid low muscle tone the deepest articular surface?
The strength of a synovial joint is largely influenced by the ligaments that reinforce it, along with the presence of an articular disc and the supportive role of muscles and tendons.
Explanation:Factors that contribute to the strength of a synovial joint include the robustness and arrangement of ligaments that surround and reinforce the joint. These ligaments hold the bones together and prevent excessive or abnormal joint motions. Moreover, the presence of an articular disc, such as a meniscus, can enhance the stability and strength of a synovial joint by providing additional cushioning, smoothing bone movements, or binding the bones more firmly. It's also important to acknowledge that muscles and their tendons contribute to joint strength by providing contractile force that indirectly supports the joint during movement.
