The correct answer are: C. heat, and E. pressure.
All metamorphic rocks need this two factors so that they can be formed from either igneous or sedimentary rocks. The metamorphic rocks form deep into the ground where the pressure is higher and the temperature is higher as well, the deeper they form the bigger the pressure and temperature they experience. According to how big of a temperature and how big of a pressure the rocks have been exposed it determines into what type of metamorphic rocks they will turn into, and according to that what kind of a texture and appearance will they have. The amount of time of exposure to heat and pressure is also key to the type and quality of the metamorphic rocks.
Answer:
A. In undisturbed rock layers, the youngest rocks are on the bottom.
C. If one rock contains pieces of another, the rock containing the pieces is older than the pieces.
Explanation:
Relative dating is a form of dating rocks in which past events in geologic records are put their proper order without necessarily knowing their absolute ages. There are several principles that helps in relative dating of rocks. These principles are:
- Principle of superposition of strata
- Law of original horizontality
- Principle of lateral continuity
- Principle of inclusion
- Principle of fossil and fauna succession
Option A and C are false statements of principle of superpositon of strata and principle of inclusion.
A. In undisturbed rock layers, the youngest rocks are on the bottom.
According to the principle of superpositon of strata, "the oldest sedimentary rock layers are usually at the bottom and the youngest on the top".
C. If one rock contains pieces of another, the rock containing the pieces is older than the pieces.
This is a false statement of principle of inclusion, the principle states that "inclusions found in a sedimentary rock are older than the rocks that contains them". Inclusions are fragments or pieces of other rocks that are found in a rock. These inclusion are believed to be older than the rocks they are found in.

An example of self-determination is the creation of Czechia and Slovakia.
Explanation:
The self-determination basically means that through the will of the people, a certain goal is a achieved usually(not always though) in peaceful manner, in this case ending a country and creating two new ones. Initially it was one country, Czechoslovakia. This country was composed of two main groups of people, the Czechs and Slovaks, and they peacefully collaborated and coexisted as a unit for several decades.
With the fall of the communism though, it became clear that the Czechs and the Slovaks have different ideals, and that they move into different directions. The people voted in a democratic manner to end the existence of Czechoslovakia, and to form to separate countries roughly divided with a border based on ethnic base. The formation of the new countries happened indeed and it was in totally peaceful manner, with the two countries retaining good relations.
Other examples of self-determination are:
- Creation of Macedonia, Serbia, Croatia, Slovenia, Bosnia out of Yugoslavia
- Creation of Austria and Hungary out of the Austria-Hungary Empire
- Creation of the Baltic states out of the Soviet Union
- Creation of Bulgaria, Greece, Lebanon etc. from the Ottoman Empire
