Front 7

annular

Back 7

occurs on: dome structures

*precip drains out from ctr

*concentric rings mark where old strata was

Front 8

deranged

Back 8

occurs: young landscapes

*have no structure

*h2o flows everywhere

Front 9

flood plain

Back 9

low-lying area near stream channel subjected to recurrent flooding

Front 10

natural levees

Back 10

develop as by-products of flooding as river spreads out + drops sediment on sides

Front 11

yazoo tributary

Back 11

flows // to main channel b/c natural levees prevent it from joining main channel

Front 12

oxbow lake

Back 12

formed by cutoff (created by looping meander eroding through) that becomes isolated from rest of the river

Front 13

water gap

Back 13

occurs where river cuts through anticlinal ridge

Front 14

wind gap

Back 14

col-like passes formerly occupied by stream that was captured + incorporated into another stream drainage

Front 15

littoral zone

Back 15

coastal environment extending from highest h2o line occurring on shore during storm to pt @ which storm waves no longer move sediments on seafloor

Front 16

shoreline

Back 16

ERO: specific contact line bt/w sea + land

Front 17

seacliffs

Back 17

ERO: formed by undercutting action of sea

Front 18

barrier spit

Back 18

DEP: material deposited in long ridge, attached @ 1 end, extending out from coast

Front 19

bay barrier

Back 19

DEP: made up of material eroded + transported by littoral drift

Front 20

lagoon

Back 20

DEP: area of coastal sea h2o cut off from ocean by bay barrier; h2o surrounded + enclosed by atoll

Front 21

tombolo

Back 21

DEP: landform created when coastal sand deposits connect shoreline w/ offshore island

Front 22

cirque

Back 22

ERO: scooped-out, amphiteater-shaped basin @ head of alpine glacier

Front 23

col

Back 23

ERO: formed by 2 headward eroding cirques that reduce arete to form high pass

Front 24

horn

Back 24

ERO: pyramidal, sharp-pointed peak resulting when several cirque glaciers gouge individual mtn summit from all sides

Front 25

arete

Back 25

ERO: sharp, sawtoothed ridge dividing 2 cirque basins

Front 26

bergschrund

Back 26

ERO: forms when crevasse opens along headwall of glacier; most visible in summer when covering snow is gone

Front 27

tarns

Back 27

ERO: small mtn lake collecting in cirque basin

Front 28

paternoster lakes

Back 28

ERO: circular, stair-stepped lakes formed in individual rock basins; look like rosary beads

Front 29

fjord

Back 29

ERO: drowned glaciated valley along seacoast

Front 30

till

Back 30

DEP: unsorted glacial ice deposits

Front 31

moraine

Back 31

DEP: marginal glacial deposits of unsorted material

Front 32

lateral moraine

Back 32

DEP: debris transported by glacier accumulating along sides of glacier + deposited along margins

Front 33

medial moraine

Back 33

DEP: debris transported by glacier accumulating down middle of glacier; results from 2 glaciers merging

Front 34

terminal moraine

Back 34

DEP: eroded debris dropped @ glacier's farthest extent

Front 35

till plain

Back 35

large flat plain of unsorted glacial deposits behind moraine; have low relief + unclear drainage patterns

Front 36

outwash plain

Back 36

area of glacial stream deposits occurring beyond glacier's morainal deposits

Front 37

esker

Back 37

sinuously curving deposit forming along melt h2o stream; develops in tunnel beneath glacier

Front 38

kettle

Back 38

forms when isolated block of ice persists; as the block finally melts, it leaves behind a steep-sided hole filling w/ h2o

Front 39

kame

Back 39

small hill of poorly sorted sand + gravel accumulating in crevasses

Front 40

roche moutonee

Back 40

asymmetrical hill of exposed bedrock; displays gently sloping upstream side smoothed by glacier + abrupt downstream side

Front 41

drumlin

Back 41

composed of till; streamlined in direction of continental ice mvmt
