Shale, a sedimentary rock, can be subjected to high heat and pressure through Choose one: A. exhumation during rifting. B. volcanism during mid-ocean ridge spreading. C. partial melting during hot-spot activity. D. burial during continental collision.

Option (D)

Explanation:

Sedimentary rocks are those that are formed from the deposition, compaction, and lithification of loose and unconsolidated sediments. This includes Shale, Sandstone and Limestone.

These sedimentary rocks can be altered into metamorphic rock by allowing it to experience higher pressure and temperature conditions. This can be taken place by the burial of sedimentary rocks during the time of the continental collision, where the rocks subjected to high pressure and temperature due to the weight of the overlying condition. The sedimentary rock 'shale' turns into a metamorphic rock named 'slate' due to the process of metamorphism.

Thus, the correct answer is option (D).

smooth muscle is composed of involuntary muscles found within the walls of organs and structures such as the esophagus, stomach, intestines, and blood vessels. those muscles push materials like food or blood through organs. unlike skeletal muscle, smooth muscle can never be under your control.
