Answer:
D) the seawater is cold and atmospheric CO2 concentration is high (relative to oceanic CO2)
Explanation:
The oceans have captured 34 gigatons (billions of metric tons) of man-made carbon dioxide from the atmosphere between 1994 and 2007. This figure corresponds to 31% of all anthropogenic CO2 emitted during that time.
The oceans function as a large CO2 sink. This oceanic sink is crucial for the atmospheric levels of this gas; Without this sink, the concentration of CO2 in the atmosphere and the extent of anthropogenic climate change would be considerably higher. Therefore, determining what part of the human-generated CO2 is absorbed by the ocean has been a priority for climate researchers.
This percentage of CO2 captured by the oceans has remained relatively stable compared to the previous 200 years, but the total amount has increased substantially. This is because while the atmospheric concentration of CO2 increases, the oceanic sink is reinforced more or less proportionally: the more CO2 there is in the atmosphere, the more it is absorbed by the oceans; until in the end it becomes saturated.
Warmer temperatures are affecting how the ocean can absorb CO2 from the atmosphere. While the ocean acts as a natural carbon sink, global climate change is decreasing its ability to absorb CO2
Over the past three decades, increases in atmospheric carbon dioxide have been largely equated by corresponding increases in dissolved carbon dioxide in seawater. The researchers found that rising temperatures are decreasing carbon absorption. and therefore cannot contain so much carbon dioxide, so the ocean's carbon capacity is decreasing as it heats up
Marco Polo (1254-1324) was a Venetian merchant believed to have journeyed across Asia at the height of the Mongol Empire. He first set out at age 17 with his father and uncle, traveling overland along what later became known as the Silk Road. Upon reaching China, Marco Polo entered the court of powerful Mongol ruler Kublai Khan, who dispatched him on trips to help administer the realm. Marco Polo remained abroad for 24 years. Though not the first European to explore China—his father and uncle, among others, had already been there—he became famous for his travels thanks to a popular book he co-authored while languishing in a Genoese prison.
Wet land reduce the evaporation rate thus improve water quality.
The area is called a floodplain and you find the floodway and the flood fringe.
Answer:
With environmental degradation and climate change, South America would lose its natural landscape and have scarce natural resources.
Explanation:
Environmental degradation is common in South American producing countries such as Brazil, Peru and Colombia, as these countries need to explore nature intensively in order to be able to commercialize products from their natural resources. However, degradation and climate change affect all South American countries because it eliminates the natural features of all countries, causing them to lose their natural landscapes, their biological diversity and diminishing the available natural resources.
