a. Earth’s polarity
b. Spin around the earth’s axis
c. Water table levels
d. Soil fertility
ANSWER: Spin around the earth’s axis
Explanation:
Groundwater depletion in India has now led to urgent measures for change. Earth’s spin around its axis is too sensitive to changes in mass of water beneath the surface of the Earth. According to the law of rotation, the 45 degree North and South latitudes will play a critical role in determining the spin. India’s groundwater depletion has caused a massive shift in the axis according to NASA scientists. Earth is still adjusting to loss of five in the last Ice Age. The reduced mass beneath North America is pulling the spin axis of Earth towards Canada at the rate of a couple of inches each year.
Findings were available through the observations of twin satellites part of the GRACE or Gravity Recovery and Climate Experiment - in this NASA collaborates with Germany to discover massive energy needed for shift in axis cannot be produced by loss of mass in Greenland alone.
