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:
Plate Tetonics
Explanation:
Plate interactions, as a result of plate tectonics, ultimately generate the various geologic settings where Earth materials can melt, metamorphose, and/or weather to become sediments.
The appropriate answer is A. Photosynthesis is tied to the carbon cycle because it is the process by which plants use carbon dioxide from the atmosphere to make food. The carbon cycle is essentially the movement of carbon between the biosphere, atmosphere, hydrosphere, and lithosphere. Photosynthesis occurs as an interaction between the atmosphere and the biosphere.
Czech Republic and Slovakia
Answer:
Explanation:
A is not correct as Botswana is one of the most stable democracies in the world, usually ranked on the 1st or 2nd place in Africa.
B is also wrong as this country is also among most stable governments on the continent. Among first ten, actually.
