Metamorphism of pre-existing sedimentary or igneous rocks occurs by heat from nearby magma called an igneous intrusion.
Answer: Option C
<u>Explanation:</u>
Contact metamorphism occurs when the hot igneous rock thrusts into some some other rock which exists previously. Then the pre-existing rock is baked by heat and during this process no additional pressure is added and this leads to the change in the mineral structure of the rock. Contact metamorphism is occurred only with heat and not by adding any additional pressure on the rock.
Answer:
- Faunalturbation
- Cultural disturbance
- Graviturbation
Explanation:
Things that could account for these chronologically older artifacts that are found above the younger artifacts in a stratigraphic sequence include;
- Faunalturbation which is caused by animals involved in burrowing
- Cultural disturbance
- Graviturbation which is the mixing of soil by movement of artifacts down a slope under gravity.
C- Deciduous
E-Coniferous
