Methane gas will be released the most into the atmosphere and intensify the global warming due to the melting of tundra.
What is Methane gas?Methane is non-toxic and poses no danger when inhaled in limited amounts. However, when large amounts of natural gas or methane displace the air, it can run out of oxygen and suffocate. It is mainly used as a fuel to generate heat and light. It can also be used in the formation of organic chemicals. Methane can form from the decay of natural substances and is commonly found in landfills, wetlands, septic tanks and sewers. The largest sources of anthropogenic methane emissions in the United States are oil and gas systems, livestock enteric fermentation, and landfills.Methane has more than 80 times the warming potential of carbon dioxide for the first 20 years after entering the atmosphere.

Aside from cultural loss, Europe would suffer from the loss of one of its primary sources of fresh drinking water, which would mostly effect the mountain towns. Losing the glaciation in the Alps would have a significant negative impact on Europe.
Another concern is that the Alps are a major tourist destination in Europe. Whether it's for a mountain event or just a simple hike, many people travel there, and the economic damage would be severe.
Due to the fact that they sell their products internationally, Switzerland currently has one of the many significant hydroelectric dams that uses the water that flows down the Alps. Without the glaciation, the amount of water running down will gradually decrease, resulting in a loss of electric energy in the country.

The reason for the formation of vesicles in igneous rocks is the rapid cooling of lava flow by water.
What is vesicles?According to the explanation by Bates and Jackson (in their book called The Dictionary of Geologic Terms, 1984), the definition of vesicles is a small cavity in an aphanitic or glassy igneous rock, formed by expansion of a bubble of gas or steam during solidification of the rock. Igneous rocks that have vesicles are just igneous rocks that are formed from the cooling of molten magma that reaches the earth's surface or this type of magma is referred to as lava. The lava is usually mixed with water when it flows over the earth's surface.
Based on the expert's explanation, it can be said that vesicles in rocks are formed when magma comes out to the surface of the earth and then cools and hardens rapidly so that the gas trapped inside the rock has not had time to be released which then forms a vesicular texture.
In conclusion, the cause of the formation of vesicles in rocks is rapid cooling of a lava flow by water.

-dense, dusty gas clouds
-young stars
Using the theories of stars, we got that dense, dusty gas clouds are more likely to find within (or on the edges of) spiral arms of a spiral galaxy than in between these arms.
The spiral arms of the galaxies are the the main production centres of young stars. The more gas and the dust available, the greater the fraction of the galaxy that can be involved in the star formation. These high-production galaxies actually tend to be dominated by their spiral arms and have relatively small central bulges. Their arms contain actually more clusters of very luminous stars and the more luminous nebulae (HII regions).
