Answer: seafloor spreading and subduction magmatism
Explanation: Continental crust are termed as the crust destroyed by plate tectonic process mostly.Continental crust usually lies above sea level and because of this existence of land life to evolve from marine life possible.
Seafloor spreading is a type of process in which tectonic plate of Earth's lithosphere separate from one another. Subduction is also a process related with continental crust that occurs when tectonic plates collide with each other rather than getting apart.
Separate Layer it's part of the "Atmosphere layers"
The rotating loops of currents that occur in the ocean are referred to as gyres.
By looking at the four graphs given and the rock layers have not been overturned. The youngest rock layer out of the four is going to be the third graph. The correct answer is the conglomerate in outcrop 3.
