Which of the following could become metamorphic rocks? a. rock a formed from magma b. rock b formed from pieces of other rocks stuck together c. both rock a and b d. neither rock a or b

Neither rock A nor B could become metamorphic rocks.  

Explanation:

Magma is the molten rock under the surface hardens into igneous rock. This rock breaks down over time under the process of weathering. These pieces of "igneous rocks" are cemented together with other bits of rocks to form sedimentary rocks. These rocks get buried under the geological processes like earthquakes. Now, coming in contact with high temperatures and magma, these rocks get changed into metamorphic rocks. So, from option A, igneous rock is formed. When combined with rock B and other rocks, sedimentary rocks are formed. Metamorphic rocks are formed in the next process. Therefore, neither of the two rocks could become "metamorphic rocks".

Hello there! i assume it is option e.  without carbon-14, it will be an impossible task to estimate the age of the fossil.hope this you! good luck : )  - hannah  ❤
