Question

which environment will most likely result in the formation of marble?
a bog in which dead plants and animals have collected over a very long period of time
an area deep underground where limestone has been exposed to intense pressure
a shallow cavity formed by the evaporation of a lake leaving behind multicolored deposits
a valley carved by a glacier which left behind rock fragments of various sizes and types

Explanation:

Marble is a metamorphic rock. Metamorphic rocks form when existing rocks (in this case, limestone) are subjected to high - pressure (and often high - temperature) conditions deep underground.

• A bog with dead plants and animals leads to the formation of organic - rich sediments (like peat, which can turn into coal), not marble.
• A shallow cavity from lake evaporation leads to the formation of evaporite minerals (like halite, gypsum), not marble.
• A valley carved by a glacier with rock fragments is related to glacial deposition (till), not marble formation.

Answer:

an area deep underground where limestone has been exposed to intense pressure
