Answer:

The correct answer is D. 4,2,3,1

Explanation:

Shale is metamorphosed into three rock types( phyllite, schist and gneissic) a dull slate with cleavage, a rock with small mica crystals with a shiny aspect, a very shiny rock with large mica crystals and a banded gneissic rock.

Shales that are subject to heat and pressure of metamorphism alter into a hard, fissile, metamorphic rock known as slate. When metamorphic grade is continually increased the sequence is phyllite, then schist and finally gneiss.

Answer:

d. 4, 2, 3, 1

Explanation:

Shale is a type of sedimentary rocks, which is characterized by it fine-grained, fissile and laminated nature. It is formed through the mixing of silt and mineral particles often referred to as mud.

Shales are metamorphosed through the heat and pressure, into a hard fissile metamorphic rock known as SLATE. SLATE is characterized by it fine-grain nature with well developed rock cleavage or salty cleavage. Then it metamorphose to PHYLLITE, which is also characterized by its fine-grained mica flakes, and it contains quartz, sericite micas and chlorite. After PHYLLITE, the shale metamorphosed to SCHIST; identified by its coarse grain nature, with mica crystals that are large enough, to unaided eyes. From there, Shale metamorphosed finally to GNEISS; a branded rock, characterized by its medium to coarse grain nature, with poorly developed cleavage.

In which climate region do temperatures rarely drop below freezing? A. tundra B. Mediterranean C. highlands D. humid continental
Lubov Fominskaja [6]
The answer would be (B) Mediterranean. The Mediterranean climate stays between 60 and 30 degrees year round, and rarely dips below freezing. We can rule out tundra because it says below freezing year round. We can also rule out the highlands because the further up in elevation you go, the colder it gets. And finally, we can rule out the humid continental because its seasons are polar opposites. The humid continental has hot summers and freezing cold winters.
(Hope this helps!)
