Webnow, using supercomputer modelling, the researchers show that the plates on which earth’s oceans sit are being torn apart by massive tectonic forces even as. Webearth is a planet defined by change, swinging through periods of intense heat and deep freeze even as oceans and continents are reshaped by the actions of. Webhere, we show, using recent global datasets of climate, river profiles and tectonic activity, that tectonics is much more strongly expressed than climate in global. Webhowever, in this study we challenge the popular view that secular cooling has been the only major control on the evolution of plate tectonics on earth since about 3. Weba key transition seemed to happen around three billion years ago: Multiple lines of evidence indicate that the tectonic regime changed profoundly at this time. Webthe process is known as plate tectonics. The term tectonics comes from a greek word meaning “to build. ”. Tectonic plates are huge moving slabs that together. Webgeologists studying the earth use scientific observation and evidence to construct a picture of what the earth looked like at different periods in the geologic past. Webthe term ‘plate tectonics’ signifies the dynamic movement and intricate interaction of tectonic plates across earth’s crust. These tectonic plates are set in motion.
