The correct answer is - C. Volcanic derived carbon dioxide gas bubbled from the lake and suffocated people and animals nearby.
In the summer of 1986, more specifically on the August 21st, a big tragedy happened in Cameroon. The Lake Nyos, located in the northwestern part of the country experienced a limnic eruption. This eruption triggered the release of very large amounts of carbon dioxide from the lake. The exact amount of carbon dioxide that was released is debatable, and the general consensus is that it was between 100,000 and 300,000 tons of the gas, though there are suggestions that it was up to 1.6 million tons.
The gas spread around very quickly, and being heavier than the air it stuck very low. In a radius of around 25 km from the lake, lot of people and animals were suffocated. The estimates are that 1746 people died and around 3,500 livestock died, not even counting the damage that has been done to the wild animals.
Answer:
The answer is latitude,elevation,vegetation and winds.
<span>In the mantle, heat is transferred as soft rock flows slowly in cycles known as convection currents. convection currents are the currents that are caused due to the process of convection. It is actually one of the three main process of heat transfer. The other two process of heat transfer are conduction and radiation. </span>
Answer:
9.) <em>Humpback Whales</em>
10.) <em>Phytoplankton.</em>
11.) <em>Sotronger upwelling winds</em>
Explanation:
9.) A primary consumer feeds on primary producers, of all the options given Humpback Whales, are the only ones meeting the criteria in the options given since they feed with plankton (a primary producer).
10.) Phytoplankton are the base of the Southern Antarctic Ocean trophic chain. In the nutrient-rich upwelling zone waters, they can reach huge blossoms and are far more common than other forms of zooplankton in this zone.
11.) The productivity of this ecosystem is influenced by the seasonal cycle of the upwelling winds, these peak during the months of December and January, carrying more nutrients and allowing trophic networks to work more efficiently and actively allowing for more productivity.
I think The upper midwest is the best choice.
