Basalt Pumice And Granite Are

Basalt is an igneous volcanic rock that forms commonly in oceanic crust and parts of continental crust.

Basalt pumice and granite are. Magma that has reached the surface is lava. Appearance of pumice is vesicular and that of basalt is dull and soft. It forms from lava flows which extrude onto the surface and cool. Its principle minerals include pyroxene feldspar and olivine.

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. Properties of rock is another aspect for pumice vs basalt. Pumice is available in beige colourless grey light green light grey pink white yellow grey colors whereas basalt is available in black brown light to dark grey colors. 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.

Molten rock material below the surface is called magma. Gabbro andesite pegmatite basalt pumice porphyry obsidian granite and tuff. Hardness of pumice and basalt is 6. Earth contains three kinds of rocks namely igneous rocks sedimentary rocks and metamorphic rocks basalt and granite are two types of igneous rocks.

Igneous rocks that solidified within the crust are plutonic or intrusive rocks. It is common both on earth and other planetary bodies.
