What technique has allowed scientists to determine when plate tectonics began? a. high-heat probing b. radiometric dating c. deep earth mining d. relative dating explain your answer! ! : )

The correct option is B.
Plate tectonic is a theory in science, which describes the movement of different sizes of plates in the earth's lithosphere. Plate tectonic is responsible for the formation of mountains, build up of earthquake, formation of new oceans, etc. For scientists to determine the time that plate tectonic started on earth, they used the method of radiometric dating. Radiometric dating employs the used of radioactive substance to determine the ages of plates that move in the earth's lithosphere.
