What was unusual about the 1986 volcano-related disaster near Lake Nyos in Cameroon? A. A volcanic eruption involved a lateral b

Grace [21]

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.

Mrrafil [7]

Answer:

a) Mass wasting - 4) Landslides or other collapses

b) Heating and cooling - 2) Type of physical weathering

c) Dust bowl - 1) Severe farmland erosion

d) Oxidation - 3) Type of chemical weathering

Explanation:

a) Mass wasting is defined as the slope movement which causes the downslope of soil, sand, and rock under the influence of the force of gravity. So, mass wasting causes landslides and other collapses due to slope movement.

b) Heating and cooling or temperature changes is a type of physical weathering. Rocks expand at high temperatures (Hot) and contracts at lower temperature (Cool).

c) Dust bowl : When grasses in farmlands are not tightly rooted, the eroding soil led to massive dust bowl and blow the grasses in the farmlands.

d) Oxidation is a type of chemical weathering. Oxidation is defined as the reaction of a substance with oxygen, when oxygen reacts with rocks and soil, it forms oxides which result in weathering.

Hence, the correct answer is:

a) Mass wasting - 4) Landslides or other collapses

b) Heating and cooling - 2) Type of physical weathering

c) Dust bowl - 1) Severe farmland erosion

d) Oxidation - 3) Type of chemical weathering

What is the history of development of the energy source?

cluponka [151]

In 1880, coal powered a steam engine attached to the world's first electric generator. Thomas Edison's plant in New York City provided the first electric light to Wall Street financiers and the New York Times.Only a year later, the world's first hydroelectric plant went on-line in Appleton, Wisconsin.By the late 1800s, a new form of fuel was catching on: petroleum.With the low-cost automobile and the spread of electricity, our society's energy use changed forever. Power plants became larger and larger, until we had massive coal plants and hydroelectric dams. Power lines extended hundreds of miles between cities, bringing electricity to rural areas during the Great Depression.(this is just a brief description)
