What is the major cause of fatalities involving small vessels? Overloaded boats are caused by DRUNKS piling all their DRUNK FIENDS into a boat that is too small and IT SINKS and EXCESS FUMES usually just BLOW UP THE BOAT and they are RARE incidences... usually when some DRUNK tries to start the engine without turning on the BILDGE BLOWER FIRST.

Limnic eruption From Wikipedia, the free encyclopedia. Lake Nyos, silty after a limnic eruption. A limnic eruption, also referred to as a lake overturn, is a rare type of natural disaster in which dissolved carbon dioxide (CO 2) suddenly erupts from deep lake water, suffocating wildlife, livestock and humans.Such an eruption may also cause tsunamis in the lake as the rising CO 2 displaces water.Scientists believe earthquakes, volcanic activity, or explosions can trigger such an eruption.uch an eruption may also cause tsunamis in the lake as the rising CO 2 displaces water.

Lake Formation Natural Processes Leading to Lake Formation. Natural lakes can form by various processes. Although many of these processes occurred in the geologic past, lakes continue to form and to be destroyed. For example, an earthquake-triggered landslide created Lake Sarez in Tajikistan only three generations ago.

- Water is lost from a pond by seepage, drainage, evaporation or overflow. Seepage loss. can be minimized by proper sealing and compac-. tion of the pond bottom, levee and sides. However, sand layers or isolated sand pockets and stump. holes can cause severe seepage problems and must.

what causes a boat to porpoise Re: what causes a boat to porpoise. Basically two root causes for porpoising......motor trimmed out too far, or the hull has a hook in it. Speed also plays into the equation. Even a boat with a hook in the hull will run smooth if you run her slow enough or don't have too much HP on the back.

What to Do When Your Car Hydroplanes Puddles can cause your car to hydroplane. Hydroplaning occurs when pressure from water in front of your tires pushes water under the tires, causing your tires to “float” on the water between your tires and the pavement. This means that your car temporarily loses traction with the road—and that’s what makes hydroplaning so nerve-wracking.

How Hydroelectric Energy Works To increase the volume of moving water, impoundments or dams are used to collect the water. An opening in the dam uses gravity to drop water down a pipe called a penstock. The moving water causes the turbine to spin, which causes magnets inside a generator to rotate and create electricity.

What is lake turnover? Confidence votes 125. There actually exists a process known as Lake Turnover and 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.

- If water is released from the top of the reservoir, it can be warmer because the dam has slowed the water, giving it more time to warm up and lose oxygen. If dams release water from the bottom of a reservoir, this water will be cooler, but may be low in DO due to decomposition of organic matter by bacteria.f water is released from the top of the reservoir, it can be warmer because the dam has slowed the water, giving it more time to warm up and lose oxygen.

- If a river meets a barrier, either a natural dam or a fabricated one, a lake will result from the buildup of water. Underground water may rise to the surface through land shifts, erosion, or springs to make a lake. Saltwater lakes can also be created by land cutting off a part of the ocean. Essentially, wherever water gathers without an outlet, a pond or lake will form. More than 300 rivers feed Lake Baikal in Russia.

Why do lakes freeze from top to bottom? because the heat from water is escaping from the water at top and not from the bottom, since the water at top is in contact with the outside world temperature. because water is a good insulator, the bottom of the lake cannot freeze first because water has to loose alot of heat in order to freeze.

Why are some lakes clear and others dark and murky? November 12, 2006 | By Sherry Boas, Special to the Sentinel. Several factors determine a lake's clarity. A lake's depth and the amount of water flowing in and out of it are important, as is the type of soil base beneath the lake's surface.ven the amount of boating has to be taken into account, because boating, like wind turbulence, stirs up particles in a lake and can contribute to a loss of visibility over the short or long term. Some lakes are naturally tea-colored. Their coloring comes from plants in the water or on land surrounding it.

- The sediment of a lake-its muddy bottom layer-contains relatively high concentrations of nitrogen and phosphorus. These can be released to water, particularly under conditions of low oxygen concentrations. The nutrients in the sediment come from the past settling of algae and dead organic matter.

- This material can. sometimes plug the sinkhole, thereby creating a lake or pond. Lakes. that once were collapse sinkholes can sometimes unplug and drain. into the underground aquifer. If the lake becomes polluted, this can. be a health hazard to people whose drinking water wells tap into. the connected aquifer.

Melting snowpack and sinking land threaten Valley communities with flooding | The Fresno Bee When land sinks, it alters the historical way water has flowed through a channel and increases the number of locations where water could overflow or compromise a levee, Tsai said. “There is usually a gradient, but when subsidence happens (the channel) becomes more flat and it causes sedimentation,” Tsai said.

Common Causes of Fish Kills in Your Pond or Lake The large oxygen swing fish kill always occurs in lakes with large amounts of submerged aquatic vegetation, floating algae or planktonic algae (pea soup water). With large amounts of aquatic weeds and algae, a lot of CO2 is consumed during the day by photosynthesis.

Causes of Floods: Reading Comprehension They can form a dam in the river, causing the water behind the dam to rise and flood the land upstream. If the dam breaks suddenly, then the large amount of water held behind the dam can flood the areas downstream too. Broken ice dams are not the only dam problems that can cause flooding. The ice in the river cracks causing the water to overflow. 2  The ice in the river cracks into pieces. 3  that eventually create a dam causing the water to overflow. 4  The water behind the ice dam collects and when the dam breaks, it causes flooding upstream.

- Unpredictable weather makes them some of the most dangerous waters in the world. Sudden storms, fire, and fog have resulted in the destruction of these many thousands of vessels. Just over twenty percent of those vessels have come to rest on the bottom of Lake Michigan, second only in quantity to Lake Huron.

Tides The force of the spinning earth (centrifugal force) causes the water to bulge on the opposite side of the earth. These bulges make the high tides. Half-way around the earth on each side between these two bulges occur the low tides. As the earth turns, the water level rises or falls.

- Precipitation on saturated land, especially land formed into a depression, will form a pond or lake. Lakes can also get their start from released water vapor and earth movements during a volcano or earthquake, plus precipitation.

- In Ohio last year, blooms of toxic algae caused mostly by farm runoff hurt the tourist economy on Lake Erie's south shore. Tourism there brings in $1.8 billion per year. In Toledo, Ohio, alone, in just one weekend, $3-$4 million was lost when restaurants and other businesses had to close due to lack of clean water.
