Same as Quiz 2, lovessss- also, someone tell me how to change my quizlet username. I made it years ago and its stupid lol
Define and describe the two lithification processes by which sediment is converted into sedimentary rock.
The two lithification processes where a sediment is converted into a sedimentary rock are compaction and cementation. Compaction is the process where a sediment progressively loses its porosity due to the effects of pressure. This can be done by rearrangement of grains under pressure, educing pore space and driving out interstitial liquid. Cementation happens when fluid deposits ions to create a cement that hardens loose sediments.
Place the following rocks in order of decreasing grain size.
Conglomerte
Sandstone
Shale
Siltstone
Place the following sediments or clasts in order of increasing grain size.
Clay
Silt
Sand
Gravel

Under differential pressure, elongate mineral grains
line up in a preferred orientation.
Which is NOT an indication that a rock is foliated?
-slaty cleavage.
-fused grains.
-banding.
-a wavy or crinkled appearance
fused grains.
Quartzite is __________________ than quartz.
denser
Which is NOT a metamorphic setting?
-the area around a magma intrusion
-a mountain valley
-a subduction zone
-a continent-continent collision
a mountain valley
Describe at least two physical features that would indicate the rock is foliated.
A foliated rock will have branded minerals. The flacks will appear to be parallel to the rock and will look layered. Foliated rocks also have linear streaks that vary in width.
How is foliation in metamorphic rocks different from layering (i.e., bedding planes) in sedimentary rocks?
Foliation in metamorphic rocks is different from layering in sedimentary rocks in regards to pressure. Differential pressure occurs in metamorphic settings, causing the grains in the rocks to line up in the same direction. That direction is perpendicular to the force and becomes the preferred orientation. Layering in sedimentary rocks causes a compressive force because of the weight of the layers. There is no elongation of the grains in layering of sedimentary rocks.
