A) marble
B) hornfels
C) slate
D) quartzite
--------------
As the degree of metamorphism increases, rocks are subjected to higher temperatures and stresses. Which of the following foliated rocks has the highest degree of metamorphism?
A) gneiss
B) schist
C) slate
-------------
Using all the characteristics of grain size, sorting, and rounding, geologists are able to
A) determine the environments where sedimentary rocks were originally formed
B) show correlations between igneous and sedimentary rock
C) choose which sediment contains ore deposits
D) determine the geologic time period sediment was formed
Explanation / Answer
Answer is (C) Slate
Nonfoliated metamorphic rocks commonly display grainy texture caused by the intergrowth of minerals with no preferred alignment. (C)Slate is NOT a nonfoliated metamorphic rock.Becuase slate is foliated rock and fine grianed formed under low grade metamorphism.
As the degree of metamorphism increases, rocks are subjected to higher temperatures and stresses.(A)Gneiss foliated rock has the highest degree of metamorphism.
Using all the characteristics of grain size, sorting, and rounding, geologists are able to A) determine the environments where sedimentary rocks were originally formed.
