Skjoldvulkaner



Mt.Bachelor, USA.

 Skjoldvulkaner dannes som  oftest ved at tyntflytende basalt-lava  strømmer ut av krateret,
og  brer seg ut over en stor overflate, innen de  langsomt stivner. Man får da  efterhvert
slake skråninger, ofte mindre enn 10 ° vinkel.

Skjoldvulkaner dannes ofte på havbunnen på s.k. hete flekker (Hot Spots).
Hawaii er et eksempel.

Shildvolcanoes are common on the bottom of the oceans, so called Hot Spots.
Hawaii is such an example.
