- D.
Non-stratification
- E.
Uplift
Correct Answer
C. Non-foliationExplanation
Non-foliation refers to the texture of metamorphic rock where the mineral grains are not arranged in planes or bands. This means that the rock does not have a layered or banded appearance, unlike foliated rocks. Instead, the mineral grains are randomly distributed throughout the rock, giving it a more uniform and homogeneous texture. Non-foliated rocks typically form under conditions of high temperature and pressure, which cause the minerals to recrystallize and rearrange without developing a preferred orientation. This texture is commonly found in rocks such as marble and quartzite.Rate this question:

What has to increase for metamorphism to occur?
- A.
Minerals and strata
- B.
Sedementation and pressure
- C.
Pressure
- D.
Pressure and temperature
- E.
Strata only
Correct Answer
D. Pressure and temperatureExplanation
Metamorphism occurs when there is an increase in both pressure and temperature. These two factors cause changes in the minerals and rocks, leading to the formation of new minerals and the recrystallization of existing ones. Pressure helps to compact the minerals and rocks, while temperature provides the energy necessary for chemical reactions to occur. Without an increase in both pressure and temperature, metamorphism cannot take place. The other options mentioned, such as minerals and strata, sedementation and pressure, or strata only, do not encompass the necessary conditions for metamorphism to occur.Rate this question:

When magma cools quickly, what kind of texture will the rock have?
- A.
Cemented
- B.
Elastic
- C.
Coarse-grained
- D.

- E.
Rocks change into metamorphic rock; if melting temperation, magma cools to form igneous rock
Correct Answer
E. Rocks change into metamorpHic rock; if melting temperation, magma cools to form igneous rockExplanation
When temperatures and pressures change, rocks undergo a process called metamorphism, where they are transformed into metamorphic rock. If the temperatures reach the melting point, the rock can melt and form magma. This magma can then cool and solidify to form igneous rock. Therefore, the correct answer is that rocks change into metamorphic rock; if melting temperature is reached, magma can cool to form igneous rock.Rate this question:
