Answer 2

water, wind, and other forces

Question 3

what does it mean if clasts are being transported

Answer 3

they are being transported from one location to another

Question 4

what does it mean if clasts are being deposited

Answer 4

when the clasts settle to the bottom of a surface

Question 5

define pore space

Answer 5

the space in between the grains

Question 6

define compaction

Answer 6

when clasts stick together due to the weight of the overlaying material

Question 7

define cementation

Answer 7

minerals precipitate slowly from a water solution and crystallize in the spaces between clasts

Answer 8

clasts get compacted together and water moves between cuasing cementation
