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

Dynamothermal metamorphism

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 structuresDynamothermal 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.

Because electrons have negligible mass, to account for the mass of the isotope, there must be 16 neutrons, 16 neutrally charged, massive, fundamental particles present in the sulfur nucleus. and thus finally, if we have the 32s2− ion, there are 18 electrons, 16 protons, and 16 neutrons.
