Geologic Cov Qauv (Part 5)
Anticlines yog quav nyob rau hauv uas txhua ib nrab ntawm cov quav dips deb ntawm lub crest. Synclines yog quav nyob rau hauv uas txhua ib nrab ntawm cov quav dips mus rau lub trough ntawm lub quav . Koj ua tau nco ntsoov qhov sib txawv los ntawm kev ceeb toom ntawd anticlines tsim ib qho "A", thiab synclines tsim hauv qab ntawm "S.
Tsuas yog li ntawd, dab tsi yog anticline hauv geology?
Hauv kev tsim qauv geology , ib tshuaj tiv thaiv kab mob yog ib hom quav uas yog ib qho zoo li arch thiab muaj nws cov txaj qub tshaj plaws ntawm nws cov tub ntxhais, whereas lub syncline yog qhov rov qab ntawm ib tshuaj tiv thaiv kab mob . Cov formations no tshwm sim vim anticlinal Cov ridges feem ntau txhim kho saum toj qhov yuam kev thaum lub sij hawm crustal deformations.
Tsis tas li ntawd, koj yuav ua li cas txheeb xyuas qhov folded strata? Ib pawg ntawm ca sedimentary txheej yog muab tais (bent los yog nkhaus) ua ntej yuav lithified (compressed rau hauv pob zeb). Quav Cov duab, nruj ntawm lub kaum sab xis, thiab symmetry tau piav qhia rau paub qhov txawv hom ntawm folded strata.
Tib neeg kuj nug, dab tsi yog syncline quav?
Syncline . Los ntawm Wikipedia, dawb encyclopedia. Nyob rau hauv structural geology, a syncline yog a quav nrog cov khaubncaws sab nraud povtseg nyob ze rau qhov nruab nrab ntawm cov qauv, whereas anticline yog inverse ntawm a syncline.
Ib qho tshuaj tiv thaiv kab mob tshwm sim li cas?
Ib tshuaj tiv thaiv kab mob yog ib qho cuab yeej cuab tam tsim los ntawm folding ntawm pob zeb strata rau hauv ib qho zoo li arch. Pob zeb txheej hauv ib anticlinal ntxiab tau Ameslikas muab tso rau hauv kab rov tav thiab tom qab ntawd lub ntiaj teb txav tau ua rau nws fold rau hauv ib qho kev zoo li arch hu ua tshuaj tiv thaiv kab mob.

Yuav ua li cas koj qhia yog hais tias ib tug transformation yog ib tug dilation?
Ib qho kev piav qhia ntawm qhov dilation suav nrog qhov ntsuas qhov ntsuas (lossis qhov piv) thiab qhov nruab nrab ntawm qhov dilation. Qhov chaw ntawm dilation yog ib qho chaw ruaj khov hauv lub dav hlau. Yog tias qhov ntsuas qhov ntsuas ntau dua 1, daim duab yog qhov loj (qhov ncab). Yog tias qhov ntsuas qhov ntsuas nyob nruab nrab ntawm 0 thiab 1, daim duab yog qhov txo qis (qhov qis)
Yuav ua li cas koj qhia yog hais tias ib lub ntsiab yog ib tug metalloid?
Lub metalloid yog ib yam khoom uas muaj qhov nruab nrab ntawm cov hlau thiab nonmetals. Metalloids kuj tseem hu ua semimetals. Nyob rau hauv lub sij hawm lub sij hawm, lub ntsiab xim xim daj, uas feem ntau ciam teb rau stair-step kab, yog suav hais tias yog metalloids
Yuav ua li cas koj qhia yog hais tias ib tug khub ntawm ratios tsim ib tug proportions?
Sim xav seb puas yog ob qho piv txwv yog proportional? Yog tias lawv nyob hauv daim ntawv feem, muab lawv sib npaug rau ib leeg los kuaj seb lawv puas yog proportional. Hla multiply thiab simplify. Yog tias koj tau txais cov lus tseeb, ces qhov sib piv yog proportional
Yog vim li cas sodium poov tshuaj twj tso kua mis suav hais tias yog ib qho kev thauj mus los uas cov kev taw qhia yog cov sodium thiab poov tshuaj tau pumped?
Sodium-Potassium Pump. Kev thauj mus los yog lub zog xav tau cov txheej txheem ntawm kev siv cov molecules thiab ions hla daim nyias nyias 'nce toj' - tiv thaiv kev sib tw gradient. Txhawm rau txav cov molecules tawm tsam lawv cov concentration gradient, yuav tsum muaj cov khoom siv protein
Yuav ua li cas koj qhia yog hais tias ib tug piecewise graph yog ib tug muaj nuj nqi?
Yuav Qhia Li Cas Yog Piecewise Function yog Nruam lossis Tsis Txuas Ntxiv. Txhawm rau qhia yog tias daim duab sib txuas tsis tu ncua lossis tsis txuas ntxiv, koj tuaj yeem saib cov ntsiab lus ciam teb thiab pom tias y point yog tib yam ntawm lawv txhua tus.(Yog tias y's txawv, yuav muaj "dhia" hauv daim duab !)
