Answers

Answer: D!!!

Explanation:

The correct answer is C, Divides the flow of river systems in the United States into east and west.

Explanation

The continental divide is the name of the main hydrological divide in America. The divide is a mountain range that divides the eastern and western slopes. Those that are considered eastern run until they reach the Arctic and Atlantic oceans, while those that are considered western run until they reach the Pacific ocean. In the case of North America, it begins in Alaska, goes through the north of Alaska to Canada where it goes south. It continues through the western region of Canada towards the south until it reaches the United States where it crosses the states of Colorado, Montana, New Mexico, and Wyoming. Later, it reaches the Mexican territory, where it takes a central road through the middle of the country until it reaches the southern countries of Mexico, such as Guatemala, Honduras, Nicaragua, and Costa Rica. According to the above, the correct answer is C. divides the flow of river systems in the United States into east and west

analysis of the causes and the consequence of droughts and desertification​

Answers

Answer:

Drought and desertification are closely related phenomena. Persisting over months or years, drought can affect large areas and may have serious environmental, social and economic impacts. While drought is a natural phenomenon, whose impacts can be exacerbated by human activities that are not adapted to the local climate, land degradation is the process of turning fertile land into less or non-productive land. In extreme cases in drylands this is called desertification. Land degradation and desertification are complex phenomena driven by un-adapted human activity in combination with land and climatic constraints. Inappropriate land use, such as monocultures, and unsustainable land management practices, such as deforestation, unsuitable agricultural practices and  overexploitation of water resources), can cause land degradation that can be further aggravated by drought.

Explanation:

The causes of droughts and desertification​ are:

Inadequate rain supply. Harmful farm praticies

The consequence of drought and desertification is a lack of food needed for human survival.
