Question

Quizplus · Accepted Answer

Sedimentary rocks are formed from the processes of weathering, erosion, transportation, deposition, and lithification, which are all part of the exogenic system. Metamorphic and igneous rocks, on the other hand, are formed from the heat and pressure of the endogenic system's processes, such as tectonic activity and volcanic eruptions. Choice A is incorrect because while tectonic activity is involved in the formation of all three rock types, it is not the defining factor. Choice B is incorrect because while metamorphic and igneous rocks are formed from endogenic processes, sedimentary rocks are not necessarily a product of exogenic processes. Choice D is incorrect because intrusive and extrusive refer to the location of igneous rock formation, not the type of system involved.
