Yuav ua li cas thaum ob continental daim hlau sib tsoo ? Hloov chaw, kev sib tsoo ntawm ob continental daim hlau crunches thiab folds lub pob zeb ntawm tus ciam teb, lifting nws thiab ua rau tsim ntawm roob thiab roob.
Tsis tas li ntawd paub yog, yuav ua li cas tshwm sim thaum lub continental thiab dej hiav txwv phaj sib tsoo?
Thaum twg continental thiab oceanic daim hlau sib tsoo , lub thinner thiab ntau ntom daim phiaj dej hiav txwv yog overridden los ntawm thicker thiab tsawg ntom continental phaj . Cov daim phiaj dej hiav txwv raug yuam mus rau hauv lub mantle hauv tus txheej txheem hu ua "subduction." Raws li cov daim phiaj dej hiav txwv nqis, nws raug yuam mus rau hauv qhov kub thiab txias ib puag ncig.
Tsis tas li ntawd, yuav ua li cas thaum ob daim phiaj continental diverge? Lub ntiaj teb lub pob zeb tau muab faib ua ntu hu ua tectonic daim hlau . Thaum twg ob daim hlau continental diverge , zoo rift kwj ha tuaj yeem tsim. Cov rift kwj ha thaum kawg yuav ua rau magma nce los tsim cov crust tshiab, tab sis feem ntau ua ntej ntawd tuaj yeem tshwm sim , lub teb chaws tawg, thiab dej rushes los tsim ib tug tshiab dej hiav txwv.
Tsis tas li ntawd nug, yuav ua li cas geologically thaum lub phaj continental tsoo nrog lwm daim av teb chaws?
Teb thiab piav qhia: Thaum ob continental daim hlau sib tsoo lub crust yog bunched li thiab ib lub roob yog tsim. Continental crust yog tsawg dua li dej hiav txwv crust.
Yuav ua li cas tshwm sim thaum sib tsoo continental?
Kev sib tsoo Continental yog ib tug phenomenon ntawm lub phaj tectonics ntawm lub ntiaj teb uas tshwm sim ntawm convergent ciam teb. Kev sib tsoo Continental yog ib tug variation ntawm lub hauv paus txheej txheem ntawm subduction, uas yog lub subduction cheeb tsam puas lawm, roob tsim, thiab ob teb chaws sutured ua ke.

Yuav daws qhov tsis sib npaug ntawm cov kab sib npaug thiab cov kab sib npaug sib npaug li cas?
Kev daws qhov tsis sib npaug ntawm qhov sib npaug yog zoo ib yam li kev daws cov kab sib npaug. Qhov sib txawv tseem ceeb yog koj tig lub cim tsis sib xws thaum faib lossis muab faib los ntawm tus lej tsis zoo. Graphing linear inequalities muaj ob peb qhov sib txawv ntxiv. Qhov uas yog qhov ntxoov ntxoo muaj xws li qhov tseem ceeb uas qhov kev tsis sib xws ntawm cov kab tawm muaj tseeb
Yuav ua li cas tshwm sim thaum daim hlau sib tsoo thiab diverge?
Divergent (Spreading): Qhov no yog qhov uas ob daim hlau txav deb ntawm ib leeg. Convergent (Colliding): Qhov no tshwm sim thaum daim hlau txav ntawm ib leeg thiab sib tsoo. Thaum lub phaj continental ntsib ib lub phaj dej hiav txwv, lub thinner, denser, thiab hloov tau yooj yim dua dej hiav txwv phaj dab dej hauv qab cov phaj tuab, nruj dua
Nws txhais li cas thaum lub meteor tsoo lub ntiaj teb?
Thaum lub meteoroid, comet, lossis asteroid nkag mus rau hauv lub ntiaj teb qhov chaw ntawm qhov ceev feem ntau tshaj 20 km / s (72,000 km / h; 45,000 mph), aerodynamic cua sov ntawm cov khoom ntawd ua rau lub teeb ci, ob qho tib si los ntawm cov khoom ci thiab cov txoj kev ntawm glowing hais tias nws tawm hauv nws sawv
Yuav ua li cas tshwm sim rau lub parallel phaj capacitor thaum lub dielectric muab tso rau ntawm daim hlau?
Thaum cov khoom siv dielectric tau qhia nruab nrab ntawm daim hlau Thiab thaum cov khoom siv dielectric muab tso rau nruab nrab ntawm daim hlau ntawm cov paib sib npaug ntawm cov phaj capacitor ces vim polarization ntawm cov nqi ntawm ob sab ntawm dielectric, nws tsim hluav taws xob teb ntawm nws tus kheej uas ua nyob rau hauv ib qho kev taw qhia opposite. rau lub teb vim
Yuav ua li cas thaum lub photon tsoo lub atom?
Photon hits lub electron thiab muab qee qhov ntawm nws lub zog thiab mus rau qee qhov sib txawv nrog cov wavelength loj dua. Electron yuav tau txais lub zog kinetic thiab txav mus rau lwm qhov kev taw qhia. Yog tias lub zog ntawm photon loj txaus kom tshem tawm cov electron ntawm atom, nws yuav ua li ntawd
