chapter 26.3 Flashcards
define clasts
small rock and mineral fragments
what types of erosion are rocks on earth’s surface exposed to
water,wind and other forces
what does it mean if clasts are being transported
its going bean moved from one place to other
what does it mean if clasts are being deposited
being dropped off
define pore space
empty spaces between clasts
define compaction
clasts stick together when weight is put on it
define cementation
minerals precipitate slowly out of a water solution and crystallize in the spaces between clasts i a process
how are sedimentary rocks formed
clasts, they get compacted, water flows through the pore spaces causing segmentation
what is another name for clasts
detritus
what are sedimentary rocks called that are mostly made of clasts
detrital sedimentary rocks
what is the decreasing size of clasts
gravel,sand, silt, or clay
which clasts size would be deposited first
(gravel) heavy substance
what are 4 common detrital sedimentary rocks
Conglomerate,sandstone, siltstone,shale
how are chemical sedimentary rocks formed
water that contains dissolved solids,and mineral crystal precipitate out of a solution and evaporation
if sedimentary rocks contain remains of living organisms what are they called
biochemical sedimentary rocks
