1, which statement describes metamorphic rock formation?
a. layers build up over time
b. magma cools and hardens.
c. once-living organisms become buried.
d. pressure causes rock to change.

2, which evidence would confirm that a given rock layer is newer than the layers around it?
a. it has been crumpled and folded, while the other layers lie flat.
b. other layers have been deposited above it.
c. it cuts through all the other layers.
d. it is horizontally-oriented.

The statement that best describes the formation of a metamorphic rock is the one that says the pressure causes the rock to change.

Explanation:

Metamorphic rocks are formed when the rocks that are already present in the interiors of Earth are subjected to high pressure and intense heat. Metamorphic rocks are denser and have a layered formation. They are formed through a process called metamorphism which literally means 'change in the form'.

May consider a group  g=({0,1},+)g=({0,1},+)where  ++  will work as the xor operator like we work in boolean algebra. note here, that ‘00’ and ‘11’ are not the usual 0 and 1 that we work with everyday. the elements are  called  ‘00’ and ‘11’ and  may not mean  zero (nothing) and one (single). ‘00’ is the identity for the given binary operator +, meaning that any element operated with ‘00’ gets us that element itself.  for a set  ss  in  g′g′  having more elements than just  {0,1}{0,1}  the values for  a+b∈sa+b∈s, such that  a∈s,b∈sa∈s,b∈s, have to be first defined, only then can you determine the value of  1+11+1. the answer could possibly have been  22  if oanswer is25,000
