The immediate cause is the removal of vegetation. Unprotected, dry soil surfaces then blow away with the wind or are washed away by flash floods, leaving infertile lower soil layers that bake in the sun and become an unproductive hardpan. Overgrazing destroys valuable plant species, leaving mostly unpalatable ones. Losses of vegetation and biodiversity threaten habitat for other species.
Mountains often bordering a desert create what is in geographic terms a "rain shadow." The mountains stop most of the rain from entering the soon to be desert. There also has to be an overall shortage of water in the area in the form of shallow aquifers, otherwise it won't become a desert. Also more often then not the soil becomes poor in nutrients because of the lack of rain fall. Thus an area meeting most of these requirements will undergo a process of "desertification." Deserts can also be man made by draining the local water sources in area of low rainfall and high drainage of soil nutrients through excessive harvesting. Cyclical climate changes and ocean currents also affect an area's susceptibility to desertification. Also water scarcity deforestation and natural or man - made disasters. Causes of desertification include overgrazing and removal of vegetation cover.
Two main factors contributing to desertification are climate change, which can lead to changes in rainfall patterns and increased aridity, and human activities such as overgrazing, deforestation, and poor agricultural practices, which can degrade the land and reduce its ability to support vegetation.
A mutually beneficial relationship in biology occurs when two different species interact in a way that benefits both parties. Key factors that contribute to the success of such a relationship include coevolution, symbiosis, and the exchange of resources or services that enhance the survival and reproduction of both species involved.
During meiosis, the two divisions of cell division result in the formation of gametes with unique combinations of genetic material. This process shuffles and recombines genetic information from the parents, leading to genetic diversity in offspring.
Two additional factors that help hold cells together are cell adhesion molecules (CAMs) on the cell surface that interact with each other, and the extracellular matrix (ECM) that provides structural support and anchorage for cells. Together, these factors contribute to cell-cell adhesion and tissue integrity.
Water availability, temperature, soil type, and fire are some of the physical factors that most influence a prairie ecosystem. These factors contribute to the type of plants that can thrive in the prairie, influence nutrient availability, and impact overall ecosystem diversity and productivity.
The Schizophyllum commune fungus has two sexes, known as "plus" and "minus." During reproduction, these sexes come together to exchange genetic material, leading to the formation of new spores. This process allows for genetic diversity and the continuation of the species.
Africa has the greatest area under risk of desertification, with around two-thirds of the continent's land being classified as drylands that are susceptible to desertification due to various factors such as climate change, overgrazing, and deforestation.
Two factors that contribute to the decentralization of parties are federalism and nominating powers.
Social factors contribute to diversity because people have different backgrounds.Individual factors contribute to diversity because people have different personalities.
The two biggest factors that contribute to suicide are mental health issues and relationships.

Media influence (e.g., idealized portrayals in advertising) and comparison to others are two factors that can affect body image. These factors can contribute to feelings of inadequacy or dissatisfaction with one's appearance.
