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.

Answer:
extrusive rocks.
Explanation:
When an igneous rock contains large crystals of minerals surrounded by the fine grained or glassy material (set in a matrix of glassy part).The texture is known as Porphyritic texture and the large crystals are known as Phenocrystals and the fine grained or glassy part is called as Ground mass.
When this Porphyritic texture showing igneous rocks are known as Porphyrites. The texture is largely found in volcanic and hypabassal rocks so these rocks are the extrusive rocks.
