It forms from lava flows which extrude onto the surface and cool.
Basalt pumice and granite are.
Granite is an igneous plutonic rock which is.
As nouns the difference between pumice and basalt is that pumice is a light porous type of pyroclastic igneous rock formed during explosive volcanic eruptions when liquid lava is ejected into the air as a froth containing masses of gas bubbles as the lava solidifies the bubbles are frozen into the rock while basalt is mineral a hard mafic igneous rock of varied mineral content.
Appearance of pumice is vesicular and that of basalt is dull and soft.
Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.
It is common both on earth and other planetary bodies.
Igneous rocks that solidified within the crust are plutonic or intrusive rocks.
All rocks of igneous origin consist of magma or molten earth that finds its way up to.
Molten rock material below the surface is called magma.
Properties of rock is another aspect for pumice vs basalt.
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.
Hardness of pumice and basalt is 6.
Igneous rocks from left to right.
Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.
Magma that has reached the surface is lava.
