Why are plate tectonics considered the reason Earth has life?

It is the consequence of the 'reason' earth has life. Earth has life, as opposed to Mars in this instance, because earth has a magnetic field due to the molten mantle with a core that generates this field. One of the dynamic consequences of this molten core is plate tectonics. read more

USGS Plates cover the entire Earth, and their boundaries play an important role in geologic happenings. The movement of these plates atop a thick, fluid"mantle" is known as plate tectonics and is the source of earthquakes and volcanoes. read more

Not only does plate tectonics enable liquid water to exist by way of regulating the temperature, but many scientists have argued water enables plate tectonics to happen."Without water the planet would be geologically dead," said Caltech's Mike Brown, discoverer of the newly reclassified"plutoid" object named Eris, which lies beyond Pluto in our solar system. read more
