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.

Multiple lines of evidence indicate that the tectonic regime changed profoundly at this time.

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.

The term tectonics comes from a greek word meaning “to build. ”.

Webthe process is known as plate tectonics.

Webthe term ‘plate tectonics’ signifies the dynamic movement and intricate interaction of tectonic plates across earth’s crust.
