Final answer:
Shock metamorphism occurs as a result of meteorite impacts, under the extreme conditions of high pressure and temperature caused by the event.
Step-by-step explanation:
Shock metamorphism occurs from meteorite impacts, so the correct answer to where shock metamorphism occurs is b) From meteorite impacts. This type of metamorphism is a result of the extreme pressure and high temperatures generated upon the impact of a meteorite with the Earth’s surface. This process can lead to the creation of unique geological features and is distinct from other types of metamorphism, such as regional metamorphism found in subduction zones or contact metamorphism near mid-ocean ridges and hot springs.
