People can be the effects that make the Earth shake more and more

Researchers have used a lot of data collected over the past 100 years to build mathematical models to track the cause of the vibration of the Earth's rotation. They found there were three agents, and humankind was responsible for one of them.

When viewed from a distance, the Earth seems to be a perfect sphere but it is not so. The Earth is uneven on all sides because the mass of rock moves and changes over time, our planet actually has a little shaking when it rotates around its axis. Currently, a new study from scientists from NASA's Jet Propulsion Laboratory and a number of other universities and scientific centers has pinpointed the cause of the imperfect rotation of the Earth - Also known as "polarized movement" - and they also see people contributing to this phenomenon .

Calculations show that the Earth is rotating its axis.

Two of the three factors identified by scientists are isotonic phenomena and convection of Malta (geological overlay).Isomorphic phenomenon occurs when thick strips of ice push the blocks of rock down, compress them, but then this pressure is released when the ice melts. As a result, the geologic layer then floats again and again over time, causing the Earth's rotation to wobble as if it were deflected. The effects of the last ice age may have compressed to a large amount of rock all over the continents that we are still feeling today in isostatic form.

Convection of geological coatings , an uncontrollable element in Earth's vibration, involves the activity of our planet. The coating on the surface of the Earth changes constantly thanks to the movement of loose rocks at the bottom of our feet. Researchers believe that these moving currents also contribute to the imperfections of the Earth.

Losing large amounts of Greenland ice also causes the Earth to deviate from its axis.

The third and final factor determined by scientists is the growing glacier of the ice in Greenland, Denmark and other regions disappear , which is the direct result of global warming. demand due to human activities. Researchers estimate that Greenland lost about 7,500 billion tons of global warming.

All of the ice is lost in the 20th century and greenhouse gas emissions are considered the main cause. The disappearing ribbons caused a significant change on the planet and also contributed to the shaking of the Earth.

NASA said: "With showing these three key findings, scientists can distinguish mass and polarization changes due to the long-term cycles of the Earth, from which we have one. little control over the factors caused by climate change . They are now aware that if the Greenland melting phenomenon increases rapidly, polarization will also increase. "
