Scientists are helping in various ways to understand how rocks in the core of the Earth helps in tectonic plates movement.
Step-by-step explanation:
The movement of the tectonic plates in the core of the Earth helps to regulate the water cycle that is very important for the planet. Plate tectonic is based on various geological phenomenon that includes mountain buildings, earthquakes and volcanoes as well as continental drift.
Plates play an important role by acting like a hard and rigid shell than the Earth's mantle. The strong outer layer is referred as lithosphere. Through research scientists found various flaws in the atomic packing in upper mantle minerals that becomes widespread under oxidising condition and thus speed of seismic waves reduces.
