why can deforestation lead to desertification?
208944
Explanation: Deforestation removes the trees which hold the soil together by their roots. Removing the trees leaves the soil bare to wind and other elements which leads to desertification since the top soil is blown away, dried out or washed away by rain.

Deforestation affects wild animals, plants and humans in at least four distinct ways: via soil erosion, which can lead to clogged waterways and other problems; via water cycle disruption, which can lead to desertification and habitat loss; via greenhouse gas emissions, which contribute to global climate change; and via ...

Which statement best describes the relationship between desertification and crop production? Desertification decreases the amount of crop production. Fossil fuels are almost always found in these types of rocks.

Ocean acidification is mainly caused by carbon dioxide gas in the atmosphere dissolving into the ocean. ... Deforestation results in fewer trees to absorb the gas. Also, when plants are cut down and burnt or left to rot, the carbon that makes up their organic tissue is released as carbon dioxide.

Deforestation not only removes vegetation that is important for removing carbon dioxide from the air, but the act of clearing the forests also produces greenhouse gas emissions. The Food and Agriculture Organization of the United Nations says that deforestation is the second-leading cause of climate change.

Today, about 31 percent of the world's watershed area is covered by forests. Deforestation in these watersheds, often caused by commodity and agricultural production, can contaminate water, fuel floods and drought, and lead to higher water treatment costs.

Firstly the removal of trees is a removal of nutrients and minerals from the soil as the source of humus is greatly reduced. ... Overgrazing, over cropping and or deforestation can lead to desertification – the spread of desert like lands due to these human activities accelerating natural erosion of soil.

Direct causes of deforestation are agricultural expansion, wood extraction (e.g., logging or wood harvest for domestic fuel or charcoal), and infrastructure expansion such as road building and urbanization. ... Most often, multiple processes work simultaneously or sequentially to cause deforestation.

Deforestation can cause a domino effect on the whole planet, including global climate change, indigenous people annihilation and biodiversity extinction. One wrong move, and the process will lead us to an empty and meaningless world. The death of plants and animals can lead to a partial loss of human life.

Forests are also cut as a result of growing urban sprawl as land is developed for homes. Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and overgrazing, which may prevent the growth of young trees.

Because trees release water vapor into the atmosphere, fewer trees means less rain, which disrupts the water table (or groundwater level). A lowered water table can be devastating for farmers who can't keep crops alive in such dry soil [source: USA Today]. On the other hand, deforestation can also cause flooding.

Deforestation and the destruction of forest habitat is the leading cause of extinction on the planet. ... On top of that, the capacity of forests to pull greenhouse gases from the atmosphere is lost as forests are cut. Forest loss contributes about 15-20% of all annual greenhouse gas emissions.

Deforestation causes 15% of global greenhouse gas emissions, which contributes to climate change. Greenhouse gases are released when forests are destroyed by activities such as illegal and unsustainable logging and from land conversion for agriculture.

How does deforestation contribute to global warming? Trees remove CO2 from the atmosphere when they photosynthesise, so without them less CO2 is removed. So deforestation means more CO2 in the atmosphere which leads to global warming.

Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.
