O que acontece quando uma área é irrigada em excesso ?

[tex] \huge \frak \purple{Answer}[/tex]

La sur-irrigation peut provoquer un drainage profond de la montée des nappes phréatiques qui peut conduire à des problèmes de salinité d'irrigation nécessitant un contrôle de l'eau par une certaine forme de drainage des terres souterraines. Cependant, si le le sol est sous irrigué, il donne un mauvais contrôle de la salinité du sol, ce qui entraîne une augmentation de la salinité du sol avec une accumulation conséquente de sels toxiques à la surface du sol dans les zones à évaporation élevée. Cela nécessite soit une lixiviation pour éliminer ces sels et une méthode de drainage pour évacuer les sels. L'irrigation avec de l'eau saline ou riche en sodium peut endommager la structure du sol en raison de la formation d'alcaline.

Explanation :

Pampas - The agricultural region Argentina's economy depends on. Pampas is known for being a large expanse of land full of succulent pasture where cattle are easily reared, including the growth of golden wheat and sunflowers. It is located in Buenos Aires.

Panama - Location of a necessary canal. Panama canal is essential because it saves ships from traveling long distances. Especially those are moving from the Atlantic Ocean to the Pacific ocean, West Coast to East Coast in America, and Europe to Australasia and South East Asia.

Andes - Longest mountain range in South America and the world at large It connects seven South American countries, including Venezuela, Colombia, Ecuador, Peru, Bolivia, Chile, and Argentina.

Answer: 3

Explanation:

The Cocos Plate is located at the following approximate latitude and longitude is 10°N and 100°W. Thus, option (3) is correct.

What is latitude?

Latitude is a term used to describe how long a line is measured from north to south. As a circle of measurement with 180 degrees of inclination, the lines are parallel to one another. An imaginary ring connecting all places that share a parallel is known as a circle of latitude.

The phrase "Cocos Plate" refers to an oceanic tectonic plate located in the Pacific Ocean and along the west coast of Central America. The name was intended to refer to the Cocos Islands. The Cocos Plate latitude and longitude are 10°N and 100°W, respectively. It had been 23 million years.

As a result, the Cocos Plate is located at the following approximate latitude and longitude is 10°N and 100°W. Therefore, option (3) is correct.

Answer: ASA or B)

Explanation: The two triangles share a line with 2 congruent angles on either side.

Answer: man activities such as agriculture, transport, energy production or urban development exert pressures on the water environment. When addressing pressures at the basin-wide scale, it has to be considered that cumulative effects may occur. Effects can occur both downstream pollutant  of a particular pressure. Addressing these issues effectively requires a basin-wide perspective and cooperation between countries.

Organic pollution refers to emissions of non-toxic organic substances that can be biologically decomposed by bacteria to a high extent. The key emitters of organic pollution are point sources like untreated or not sufficiently treated municipal wastewater from households, industries and major agricultural farms. The primary impact of organic pollution on the aquatic environment is dissolved oxygen depletion due to biochemical decomposition of organic matter. In the most severe cases this can lead to anaerobic conditions, to which only some specific organism can accommodate. The pollution with organic substances can therefore cause changes in the natural composition of the aquatic flora and fauna. It can also be associated with health hazards due to possible microbiological contamination of waters.

Nutrient pollution is caused by releases of nitrogen (N) and phosphorus (P) into the aquatic environment. Nutrient emissions can originate from both point and diffuse sources. Point sources of nutrient pollution are similar to those of the organic pollution. Diffuse pathways such as overland flow, urban runoff, soil erosion, tile drainage flow and groundwater flow can remarkably contribute to the emissions into surface waters transporting nutrients from agriculture, urban areas, atmosphere and even from naturally covered areas. Impacts on water status caused by nutrient pollution can be recognized through substantial changes in water ecosystems. In case of nutrient enrichment, water bodies can turn to eutrophic state where the growth of algae and/or macrophytes is substantially accelerated. Eutrophication severely impairs water quality and ecosystem functioning (e.g. oxygen depletion, toxicity, overpopulation of species) and might limit or even hinder human water uses as well (e.g. recreation, fisheries, drinking water supply).

Hazardous substances pollution involves contamination with priority substances and other specific pollutants with toxic effects on aquatic organisms and humans. Hazardous substances can be emitted from both point and diffuse sources. The most important sources of hazardous substances pollution are industrial facilities, agriculture (pesticide and contaminated sludge application), contaminated and mining sites, households and public buildings via municipal wastewater and urban run-off (deposited air pollutants, litter, combined sewer overflows). Moreover, significant volumes of deadly toxins can be unexpectedly flushed directly into watercourses by occasional industrial accidents or floods. Hazardous substances can pose serious threat to the aquatic environment. Depending on their concentration and the actual environmental conditions, they can cause acute (immediate) or chronic (latent) toxicity. Some of the hazardous substances are persistent, slowly degradable and can accumulate in the ecosystem.

Surface waters suffer significantly from hydromorphological alterations. Interruptions to river and habitat continuity, disconnection of adjacent wetland/floodplains, hydrological alterations and future infrastructure can hugely impact  water status and therefore will need to be addressed in future.

It is assumed that the effects of the floods that impacted the countries in the Danube River Basin in recent years were worsened due to deforestation, the destruction of natural floodplains and climate change. Preserving the natural habitats of the many species living in the basin is a constant struggle. The habitats of pelicans in the Danube Delta and sturgeon species are particularly under threat.

Major problems affecting aquatic ecosystems in the Danube River Basin

Excessive nutrient loads (particularly nitrogen and phosphorous)

High amounts of organic substances originating from untreated or poorly treated wastewater

Changes in river flow patterns (hydromorphological alterations) and its effect on sediment transportation

Contamination with hazardous substances (including heavy metals and organic micropollutants)

Accidental pollution from industrial and mining facilities

Degradation and loss of wetlands

Human pressures and impacts are investigated and addressed in the frame of the Danube River Basin Management Plan (according to the WFD).
