Question

Regional metamorphism ________. A. takes place at cool temperatures and low pressure B. takes place at cool temperatures but high pressure C. is another name for thermal metamorphism D. is another name for dynamothermal metamorphism

Answer 1

Dynamothermal metamorphism

Step-by-step explanation:

• Dynamothermal metamorphism takes place under the effects of direct pressure and heat.
• The heating element promotes the recrystallization and shearing stress not only facilitates recrystallization but is also helpful in deforming the rocks producing newly formed structures
• Dynamothermal metamorphism can be said as regional in character as it is related geographically and also from its origin to large orogenic belts (An orogenic belt involves a series of geological processes collectively called orogenesis in which a continental plate shrinks and is pushed upwards to form one or more mountain ranges)

∴ We can say Regional metamorphism is another name for dynamo thermal metamorphism.
