According to a recent study, the Earth’s pole has moved several centimeters over the past three decades. Wondering what could be the cause? Read to find out.
Does the earth move?
The Journal of Geophysical Research has published a new study showing that the Earth’s poles have moved over the past three decades. displacement is about 80 cm. What could be the cause of this change?
situation
The Earth’s pole has moved about 80 centimeters to the east over the past three decades. The change occurred between 1993 and 2010, according to Phys.org.
Reason
The main reason for this is the pumping of groundwater. The Earth’s axis of rotation shifted in the 1990s. This shift was previously thought to be the result of groundwater withdrawal, thawing, and other factors leading to sea level rise.
However, in 2016, researchers discovered that water has the power to change the Earth’s rotation.
Until this discovery, little was known that these rotational changes were due to the contribution of groundwater.
According to Phys.org. site, it is estimated that humans have pumped out 2,150 billion tons of groundwater. This equates to a sea level rise of 6 millimeters between 1993 and 2010.
