Geologists have classified rocks into three major groups of rocks which are:
inorganic, organic and chemical rocks
igneous, sedimentary and metamorphic rocks
metamorphic, chemical and non chemical rocks

Basalt forms _____________ and can be found ______________.
From the solidification of quickly cooled rock; as oceanic crust
From the re-melting of ultramafic rock in the upper mantle; all over the Earth as the ocean floor
From the solidification of mafic minerals; beneath the oceans
All answers are correct
Granite forms:
From the 'remelting' of basalt where only the lighter minerals (felsic) melt out
From subducting oceanic crust
From mostly felsic minerals that are extracted from mafic rock
