5 facts you do not know about Antarctica
Antarctica Antarctica is the Antarctic continent that contains Antarctica and is located in the Antarctic Antarctic as we mentioned shortly. It is the fifth continent in terms of area after Asia, Africa, North America and South America which is almost double the size of the continent of Australia.
Snow covers 98% of the southern continent with a thickness of up to 2 km !! Temperature up to 89 under zero !! However, it is surprising to know that the southern continent is a desert with a rainfall rate of barely 200 ml in coastal areas and even less on land!
Snow in the southern continent is growing in size and not vice versa
Yes, this is true. Antarctic snow has increased to 19.5 million square kilometers last year, an increase of 4.5 percent over 1981. We must distinguish between sea ice and land-based snow. Scientists point to its melting as land ice because sea ice The ocean melts every year in the summer automatically.
What is happening is that melting snow from the land, thanks to the winds and slopes, causes an increase in the size of the snow in the ocean, as well as other factors such as extreme changes in ocean temperatures and salinity, which contribute to finding new areas available for snow in the ocean and reducing their melting. The same factors contribute to the melting of the Earth's snow. Wind, for example, contributes to the impact of the ocean's water cycle, which produces warm water, which in turn dislodges the land's snow from the bottom causing it to melt.
They are volcanoes inevitably
The west of the continent is the most prone to melting of the snow, and it also has many volcanoes active between its sides. So can these volcanoes be the reason for melting and not global warming?
The answer to this question is no, why? First, because many places around us prove that volcanoes and ice can be found in one place, for example, Island, which contains many active volcanoes and is still snowing as it is. Secondly, some evidence shows that lava does not actually melt ice. In some way, snow returns. In addition, volcanic activity in the western part of the continent has not changed since the Sunnites, so it is unlikely to be soluble. Scientists have found that volcanic eruptions the size of those in the area are insufficient in any way to melt thick snow there.
Plot of global warming
Some 97% of scientists believe that humans are the cause of global warming, but recent observations in the western icy continent have shown that the continent's largest ice shelf has begun to collapse. Researchers say there are no correlations with temperature but you can imagine it as an effect. Domino stones that affect each other and scientists predict that these collapses will continue for centuries and no one can stop them as there is no melting or collapse of any peaks or mountains that limit the speed of collapse and the valleys are a paved road.
Ice Age is coming
Scientists believe that over the past 900,000 years the Earth has gone through cycles of temperature rise and decline every 100,000 years alternately, and if it continues to do so in the near future, the Earth is heading towards a certain ice age, but it is disturbing that there is an important factor in the picture. What is it? .. We! In addition to gases, aircraft waste, high carbon dioxide and other pollutants that will inevitably affect this natural cycle of the environment.
No one will drown
Most of the snow in Antarctica is based on land and extends to the giant icebergs of the oceans, so most of the snow does not affect the current displacement of water, and the ice size actually decreases when it melts so the ocean level will decrease, not vice versa.
In addition, the scientists found that melting glaciers at the present time and since the end of the Ice Age was the reason that the land began to move towards the Arctic by 0.88 millimeters each year as a result of the decline of snow masses that result in the rise of land again.
