The earth itself stores a wealth of energy, and natural disasters such as thunderstorms, floods, typhoons, tsunamis, earthquakes can cause huge damage. Some physicists have discovered the natural destructive power of the earth, the military significance and value of its influence, and by continuously studying nature The characteristics and laws of the phenomenon, trying to grasp the impact of natural disasters on the military, and using natural energy through some physical methods, such as artificially creating strong winds, rainfall, lightning, tides, tsunami, fog, etc. , can achieve military offensive and The purpose of defense; the use of artificial lighting methods can effectively drive heavy clouds and reduce the energy and time of lightning so that the command and control facilities of military operations are not disturbed. What's the most appropriate summary of this text? ['All countries focus on the use of geophysical technology to improve military strength.', 'The natural destructive power of the earth is two-sided and cannot be attributed to disasters unilaterally.', 'Geophysical technology opens up new directions for the effective use of natural energy in the military field.', 'Technology in the house of the earth is an indispensable important military technology in modern military development.']
