Laattatektoniikka

Uutta tietoa maapallon vedestä ja laattaliikunnoista

Maa­pal­lon syn­ty­pro­ses­sin mu­kaan pla­neet­tam­me pin­nal­la pi­täi­si olla enem­män vet­tä, kuin mitä sitä täl­lä het­kel­lä on. Brit­ti­läi­sen tut­ki­muk­sen mu­kaan se­li­tys löy­tyy laat­ta­lii­kun­nois­ta: Kun me­rei­nen laat­taa pai­nuu man­te­rei­sen laa­tan alle, se vie mu­ka­naan kuo­ren alla ole­vaan vaip­paan vet­tä, joka on laa­tan lai­das­sa ole­vas­sa su­las­sa mag­mas­sa. Ai­ko­jen ku­lu­es­sa val­ta­mer­ten vet­tä on siis va­ras­toi­tu­nut suu­ri mää­riä vaip­paan.
