Article 1: Limnic Eruption edit

1st edit: Added possible cause/trigger of a limnic eruption. Source found through LSU library resources. Below is my exact addition. No plagiarism was found in this addition after reviewing.

"Another possible cause of a limnic eruption is the the gradual development of saturation at certain depths which can trigger the spontaneous development of gas.^[4]"

2nd edit: Found research done on Lake Kivu specifically and added to the "Lake Kivu's potential danger" section of the wikipedia article. Below is my exact addition. No plagiarism was found in this addition after reviewing.

"Two main changes in Lake Kivu's physical state that have brought attention to the possible limnic eruption are the high rates of methane dissociation and the rising surface temperature.^[11] Thorough research of historical and present temperature monitoring show that Lake Kivu's surface temperature is increasing by approximately 0.12 °C per decade.^[11]"

Edit 3: I added links to the wikipedia articles about "methane" and "Rwanda" to give the reader more background information about the trigger and location of the possible Lake Kivu limnic eruption.

Article 2: Tornadoes

1st edit: Added more specifics about how the pressure of a storm system can effect the longevity of a tornado.

"The low pressured atmosphere at the base of the tornado is essential to the endurance of the system.^[51]"

2nd edit: There was already a good coverage of radars and tornado detection but I did add in to clarify that Doppler radars can be used to predict tornadoes by detecting mesocyclones.

"Doppler radar systems can detect mesocyclones within the supercell of a thunderstorm. This allows meteorologists to predict tornado formations throughout thunderstorms.^[90]"

Edit 3: I added a link to the word "mesocyclone" because mesocyclones were not mentioned in this section yet and the reader could use clarification on the topic for full comprehension of the usefulness of doppler radars.

There was no instance of plagiarism in any of my edits.

Article 3: Tornado Alley

There was little mention of the significance of the geographical location of tornado alley and what air temperatures and directions were making this alley an ideal environment for tornadoes to form.

"In Tornado Alley, warm, humid air from the equator meets cool, dry air from Canada and the Rocky Mountains. This creates an ideal environment for tornadoes to form within developed thunderstorms and super cells.^[17]"

Also added hyperlinks to the terms "Rocky Mountains" and "super cell," therefore the reader can have clarification of temperature differences as well as a supercell's influence on a tornado's formation.

There was no instances of plagiarism found in my edits/additions.

Article 4: Avalanches

Edit 1: The avalanche article did not give a clear description of the pathway of an avalanche. I added a sub heading to the "Formation and type" section of the article. This way the reader can have a full understanding of how avalanches move down a slope as well as how a slope's steepness can effect the speed, momentum and movement of the avalanche. I also hyperlinked the word "mass movement" to the "mass wasting" article. This was the reader understand that the two words are synonyms. This also allows the reader to get a bigger perspective of mass movement and how avalanches compare to other example of mass movement. I also hyperlinked the term "snowpack". While presenting this topic I realized the complexity of the concept of a snowpack. This allows the reader to clarify their understanding of unstable and stable snowpacks. My full edit is below:

Avalanche pathway

As an avalanche moves down a slope it follows a certain pathway that is dependent on the slope's degree of steepness and the volume of snow/ice involved in the mass movement. The origin of an avalanche is called the Starting Point and typically occurs on a 30-45 degree slope. The body of the pathway is called the Track of the avalanche and usually occurs on a 20-30 degree slope. When the avalanche loses its momentum and eventually stops it reaches the Runout Zone. This usually occurs when the slope has reached a steepness that is less than 20 degrees. These degrees are not consistently true due to the fact that each avalanche is unique depending on the stability of the snowpack that it was derived from as well as the environmental or human influences that triggered the mass movement.

Edit 2: I added the Glory Bowl Avalanche to the list of notable historic avalanches in this article. There was only one avalanche referenced from the United States in this section and it was a good example of a human triggered avalanche. I also hyperlinked the term "Teton Mountain Range" that way the reader could understand the geographical location of this avalanche.

"On December 1st, 2000, the Glory Bowl Avalanche formed on Mt. Glory which is located within the Teton Mountain Range in Wyoming, United States. Joel Roof was snowboarding recreationally in this backcountry, bowl-shaped run and triggered the avalanche. He was carried nearly 2,000 feet to the base of the mountain and was not successfully rescued."
