Yog li ntawd, cov kws tshawb fawb ntseeg tias cov Islands tsim vim muaj cov Hawaiian " kub qhov chaw , " ib cheeb tsam sib sib zog nqus hauv lub ntiaj teb lub tsho tiv no los ntawm qhov kub nce, qhov kub no ua rau cov pob zeb yaj (magma), uas tom qab ntawd thawb los ntawm cov pob zeb thiab ua kom muaj zog.

Kuj tseem paub, Hawaii Islands tau tsim los ntawm hotspots li cas?

Cov Hawaiian Islands tau tsim los ntawm kev ua volcanic. Txhua kob los yog submerged seamount nyob rau hauv cov saw yog successively laus mus rau sab qaum teb hnub poob. Volcanoes kuj tau daim ntawv nyob rau hauv nruab nrab ntawm ib lub phaj, qhov twg magma nce mus txog rau thaum nws erupts nyob rau hauv lub hiav txwv, ntawm qhov hu ua kub qhov chaw .”

Tsis tas li ntawd, qhov chaw kub ntawm Hawaii nyob qhov twg niaj hnub no? Lub Hawaii hotspot yog lub roob hluav taws kub kub nyob ze ntawm lub npe Hawaiian Islands tuaj , nyob rau sab qaum teb Pacific Dej hiav txwv.

Ntawm no, yog vim li cas ho muaj hotspot nyob rau hauv Hawaii?

Hawaii yog geologically ib qho chaw tshwj xeeb hauv ntiaj teb vim nws yog tshwm sim los ntawm ib tug ' kub qhov chaw .' Feem ntau cov Islands tuaj muaj nyob ntawm thaj tsam tectonic phaj los ntawm cov chaw sib kis (xws li Iceland) lossis los ntawm thaj chaw subduction (xws li tus Aleutian Islands tuaj). Ib txhia ntawm cov volcanoes tsim mus txog tus nto ntawm tus dej hiav txwv thiab ua Islands tuaj.

Cov chaw kub thiab cov phaj tectonics txoj kev xav li cas rau cov hnub nyoog sib txawv ntawm Hawaii Islands?

Raws li cov phaj tectonics txoj kev xav ,ua a phaj txav tshaj ib kub qhov chaw, magma feem ntau nkag mus rau saum npoo, yog li tsim cov qauv volcanic.
