Because Granite Is Less Dense Than Basalt Continents

Basalt is more common in oceanic crust while granite is more common in continental crust.

Because granite is less dense than basalt continents. Granite is 70 silicon. Basalt is denser than granite because basalt is a an oceanic type of rock so it has had more pressure from the ocean making it denser than granite because granite is a continental type of rock. Basalt can form in a few days to months whereas granite plutons can take millions of years to cool and harden. Granite is less dense than basalt mainly because granite is made up of lighter mass minerals like quartz and feldspars without much in the way of heavier mass weightier mafic minerals like pyroxenes and hornblende.

All rocks of igneous origin consist of magma or molten earth that finds its way up to. The key difference between basalt and granite is that basalt is mostly occurring on ocean floors while granite is in the crust of the earth in all continents. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks. Granite is very much less dense than basalt.

Summary of basalt vs. Hope it helps you. Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of.
