Geology Midterm 2

Foliation degrees and draw out chart kinda

Shale-thin dull layers

Shiest-shiny with observable layers

Gniess-thick with obervarble crystals

migmatitic-thick with very observable crystals

3 tidal zones and schedules

Weaters law

Weaters-weather. enviornemtents beside each other eventually land ontop each other

3 types of longshore deposits

2 types of pressures

think of box being squished into small space,confining, direct

4 types of river styles

4 types of allochems 

fossils

oolites-small spherical sand sized grains, each with laters, 

intraclasts-eroded peices of preexisting rock

pellets-lithified poop

wilson cycle

rift occurs causing ocean to form, ocran eventually sloses up causing 2 plates to converge and mountains to form, mountains get eroded and cycle continues

types of siesmic waves

appalation mountain origin

mountains in convergent and rift

4 physical traits for transported sediments

roundness, sphericity, sorting, grain size

types of sedimentary enviornments 

3 examples of parent rock

biotite to amphibolite sandstone to quartz shale to slate

4 types of sedimentary structure

ripples, crossbed, graded bedding, mudcracks

3 main types of sedemintary rocks

4 sediment types and rocks affiliated w each one

4 things tide depend on

Foliation stress types

where does metamorophism happen and what kinda rocks r present

stress vs strain

joints, dipslip + strike slip faults

ductile deformation, plunging fold, basin dome + connection to syncline vs anti cyncline 

archbishop ussher

used bibliological geneologies to fix time of earth

william smith

first map of england

james hutton

charles lyell unformitasnisms and 3 elements

nicholas steno and 3 principles

know all 4 eons

explain the roundness/ spericity for supermature, mature, submature and immature sedimentary rocks

supermature-rounded quartz

mature-subrounded

submature-subangular

immature-angular

the more mature it is the more weathered it is

A foraminifera

Stromataporoids

A bivalves

Byozoans

crinoids

1. open water

2. bottom dwelling

3. freshwater and saltwater

4. attached to hard surfaces

5. attached to sea floor

label this and describe the facies
