Like NAFTA, USMCA is a free trade agreement, but it has been made in a manner that economic freedom is even greater between the countries, while also making the region a type of economic union to counter and prevent the Chinese growing influence.
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.
