What is the "bubble" that swells all over the world?

In 20 14 years, after investigation, scientists found that the gas in bubbles is methane, the content of methane is 1000 times that of air, and the content of carbon dioxide is 5 times that of air. In order to prevent local residents from finding unnecessary dangers, scientists decided to mark this area with bubbles below, and the marking work was not completed until 20 17.

Recently, scientists have found many bubbles in Siberia. These bubbles do not exist in liquid, but under solid matter. The bubble area is Bere Island in Siberia, a relatively remote place. The number of bubbles found is 15, which is not much. There are bubbles under the wet ground, so the ground becomes very elastic. If people bounce on the ground with bubbles, they will feel that they are on a sponge.

Scientists have found that these soil bubbles are rich in methane and will explode at any time, so they remind nearby residents not to get close to these soil bubbles. Before this, some people tried to make a "spring trampoline" with clay bubbles, which was very interesting.

In fact, the soil bubble is very fragile, and it is full of gaseous methane, which can easily trigger a series of explosions. A little carelessness will hurt people around, and scientists are not sure about the content of methane. Once there is danger, the consequences are unimaginable. The world is very big. Let's do something to understand the world in a limited time.
