basalt
Basalt and Granite are igneous rocks which are very hard.
Basalt is an extrusive, mafic igneous rock, which means that it solidifies from lava at or near the surface, and is composed partly of iron and magnesium minerals. Granite is an intrusive felsic igneous rock, meaning that it solidifies from magma below the surface, and is relatively high in minerals containing silicon and aluminum. Basalt has a higher specific gravity than granite, and is also darker than granite. Basalt may have visible air pockets, frozen in place when it solidified from lava. Granite will not exhibit this characteristic. Basalt has mineral crystals that are not visible with the naked eye. Granite has visible mineral crystals.
The majority of Earth's crust is composed of igneous rocks, particularly basalt and granite. These rocks form through the cooling and solidification of molten material from beneath the Earth's surface.
Basalt is extrusive, formed from cooling lava, and has a fine-grained texture with minerals like pyroxene and plagioclase feldspar. Granite is intrusive, formed from cooling magma underground, and has a coarse-grained texture with minerals like quartz, feldspar, and mica. Both are igneous rocks, but basalt is dark-colored and dense, while granite is light-colored and less dense.
Granite has more silica than basalt in it.
Basalt and Granite are igneous rocks which are very hard.
Basalt typically has smaller crystals than granite. This is because basalt cools and solidifies quickly on the Earth’s surface, limiting crystal growth, while granite forms beneath the surface and has more time for larger crystals to develop.
Granite and basalt are made when magma cools. Granite forms from slow-cooling magma underneath the Earth's surface, while basalt forms from rapidly-cooling magma on the surface.
Ancient Egyptian obelisks are made of basalt or granite, but the Egyptians favored granite.

Yes, both granite and basalt can be found in volcanoes. Basalt is a common type of volcanic rock formed from the rapid cooling of lava, while granite can be present in volcanic environments due to magma cooling and crystallizing beneath the Earth's surface before being exposed through volcanic activity.

Granite forms deep underground as felsic magma cools, mostly under continents. Basalt forms at or near the surface as mafic magma cools, typically on oceanic plates.
No. Granite and basalt have different compositions and form under different circumstances.
Granite - coarse grained. Basalt - fine grained.

Basalt does have a greater specific gravity. Granite is not as dense as basalt.
