When was the last limnic eruption?
A Limnic eruption is a rare natural disaster. It is when carbon dioxide suddenly erupts from deep lake water, suffocating wildlife, livestock and humans. Limnic eruptions may also cause tsunamis in the lake as the rising carbon dioxide displaces water.
What uses the dissolved carbon dioxide in a lake?
Autotrophs are organisms that can synthesize their own food. They will use the carbon dioxide in the process of photosynthesis.
Is smoke carbon dioxide?
Yes, the earth's carbon cycle moves carbon, and carbon dioxide in and out of the atmosphere. Carbon is released from rotting vegetation, rotting trees, melting tundra and lake beds, aerobic (with oxygen) decomposition of landfills, and from the breath of living creatures. It also moves in and out of the surface of the oceans. Trees and vegetation usually absorb carbon, but some carbon is emitted at night.
Can a lake contain carbon dioxide?
Yes. There have been several incidents where dissolved carbon dioxide gas bubbled up out of deep lakes violently. Then the giant cloud of heavier-than-air gas spread out down valleys, killing lots of people and livestock by suffocation from lack of oxygen.
What are the two largest greenhouse gasses?
In every measurable way the two that have the most affect on the natural greenhouse effect are water vapor (up to 75%) and Carbon Dioxide (5 to 25%).Both are naturally occurring, yet man is producing ever larger portions of CO2. We are currently producing around 3% of all annually produced CO2.A:Referring to the accelerated greenhouse effect we are now experiencing:Carbon dioxide (CO2) is the greenhouse gas responsible for the accelerated greenhouse effect, added by humans burning fossil fuels. CO2 is having the largest effect on the recent increases in global temperature.The other powerful greenhouse gas is methane (CH5) which is produced by cattle, animal manure and is released from melting tundra and lake beds. It is 21 times more powerful than CO2.

Why does the process of dissolving carbon dioxide in water cause the water to become acidic?
Because water and carbon dioxide make carbonic acid. The equation for it is: H2O + CO2 --> H2CO3. This only happens under pressure, however, so you can't just make it happen in your kitchen sink. This is what happens in soda cans, and that lake in Africa that overturns every few years.
What is lake turnover?
There actually exists a process known as Lake Turnoverand an event known as Lake Overturn (Limnic Eruption). The first, known as lake turnover occurs on many large and/or deep bodies of water. As air temperatures drop so does the water temperature of the upper layers of a body of water. As these upper layers cool they become denser and heavier. Eventually they become cold enough and heavy enough to the point they begin to sink. As this heavy dense layer sinks it displaces the water at the lake bottom forcing the lower layers to the surface. It is the unique properties of the water molecule which causes water to contract down to 40 degrees F and then to begin expanding at 39 degrees F to 32 degrees F that makes this process possible without freezing the lake through. The second, known as lake overturn is also known as limnic eruption and, by all accounts, is much more rare and can be deadly. Limnic eruption occurs when a layer of carbon dioxide rich water at the bottom of a deep body of water is displaced or disturbed and rises rapidly and erupts from the surface releasing the gas into the atmosphere. These eruptions have been identified as the cause of mass death events in villages at Lake Nyos in Cameroon, Africa when these areas were overcome with the heavier-than-air carbon dioxide resulting in the suffocation of those close to the ground or unable to flee. As currently understood, carbon dioxide rich springs seep into the lake bottom and over time a thick layer of this carbon dioxide builds up in the lower portion of the lake. Pressure from the upper layers of water keeps the gases from escaping to the surface similar to how the cap on a bottle of soda water keeps the gases from escaping. This gaseous layer continues to build until it is displaced, perhaps by vulcanism, seismic activity or landslides. When any of these events occur and bring the carbon dioxide rich bottom lake layer to the top of the lake you have what is know as lake turnover.

What is the meaning of eruptions?
A Limnic eruption is a rare natural disaster. It is when carbon dioxide suddenly erupts from deep lake water, suffocating wildlife, livestock and humans. Limnic eruptions may also cause tsunamis in the lake as the rising carbon dioxide displaces water.
Does CO2 affect acidity in lakes?
Carbon Dioxide, when mixed with distilled water, creates a weak acid. How it affects acidity in a lake depends on the particular lake and the minerals it contains. It would have a strong effect in the New England states and almost no effect in the alkaline soils of the west.

When excess fertilization drains into a lake what may occur?
eutrophicationeutrophicationFertilizer in a lake helps algae grow. Up to a certain point, that is good. The algae turns carbon dioxide into oxygen and adds oxygen to the water. However, after that point, the algae covers the lake. Oxygen from the air can not get to deeper water. Dead algae falls to the bottom of the lake and decomposes. The process of decomposing uses up oxygen. The amount of oxygen in the lake drops below the point where fish can survive. Thus, over fertilization leads to a fish kill.

How do you put monitors in a sentence?
Monitors observed the students during the test. Carbon dioxide monitors registered high CO2 in the house. The scientist monitors the level of bacteria in Lake Erie.
