Pls where do most metamorphic processes take place? a. at least a hundred kilometers below earth’s surface, in the mantle b. in the first few kilometers below earth’s surface c. at least a few kilometers below earth’s surface, in the lithosphere and upper mantle d. in the mantle and upper core

A. at least a hundred kilometers below Earth’s surface, in the mantle

Explanation:

Metamorphic rocks are rocks which are formed from existing rocks. They change their form which results in their formation. Examples include marble,Schist etc.

They are formed under conditions such as temperature greater than 150 to 200 °C and pressure of 1,000 bar and above thereby causing intense physical or chemical change.

Their formation occurs at least a hundred kilometers below Earth’s surface, in the mantle .

in the year 2850, humans successfully colonized mars. the martian modules that were constructed could hold only a small population of people. it is now a century later, and the population on mars has grown to 600 people. of the current mars population, 45 people express the recessive phenotype for phenylketon- uria (pku) syndrome (pp genotype).
