Match the following terms to their best definition. A. Sediment sorting Stratification of sediments and rocks B. Layering Range of particle sizes C. Texture Grain size D. Grain Roundness Loss of edges?
Sediment sorting-Range of particle sizes layering- stratification of sediments and rocks texture- grain size grain Roundness- loss of edges on sediment grains (just took the Quiz of apex!)
What occurs when the weight of overlying sediment forces the sediment grains to fuse?
A sedimentary rock is formed.
Which type of sediment would undergo more compaction grains of sand or grains of clay?
Grains of clay due to their flat structure.
What type of rock has layers and is made from grains?
Sediment rocks
How do grains of sediment stick together to form rock?
pressure or cementing
What doesn't affect the movement of sediment along the shore?
size of sand grains
Terrigenous sediment consists of mineral grains eroded from?
mid ocean ridges
Can transportation be another word for erosion?
No, erosion loss of sediment , transportation is the process by which that sediment is removed.
How is permeability related to the size of the grains that make up the sediment?
If the size of the sediment is very small then it would have poor permeability But if the size of the sediment was large then it would be easier for liquids to flow through.
Why do most mudflows occur in dry mountainous regions after a heavy rainfall?
Adding too much water to sediment increases the pressure between grains and causes a loss of cohesion, which can cause the sediment to behave as a fluid. Mountainous regions often have steep slopes that can fail and produce mudflows. Arid regions generally have little vegetation to reduce runoff and hold sediment in place.
What kind of sediment consists primarily of of mineral grains that were eroded from rocks on land?
hydrates
