Rocks with basaltic composition are found near the earth's surface in the area of volcanoes. They are formed from the rapid cooling of basaltic lava.
Most rocks with a basaltic composition are typically found in oceanic crust, such as the ocean floors and mid-ocean ridges. Basaltic rocks are also common in volcanic regions like Hawaii and Iceland.
Oceanic crust is made of basaltic rock. The rocks formed from hotspot volcano lavas are also often basaltic too.
Basaltic Magmas are dark colored, heavy and are ferromagnesian in composition, so they most times do not form light colored rocks, rather, the Felsic Granitic Magma forms the light colored rocks with lower densities.
Granite igneous rocks are lighter in color than basaltic rocks primarily due to their mineral composition. Granite is rich in light-colored minerals such as quartz and feldspar, which contribute to its lighter hues. In contrast, basaltic rocks contain a higher proportion of dark-colored minerals like pyroxene and olivine, resulting in their darker appearance. This difference in mineralogy reflects the varying magma compositions from which these rocks are formed.

Usually not. Although it is possible to have pyroclastic material with a basaltic composition, most basaltic rocks are from simple lava flows.

Igneous rocks containing mostly plagioclase feldspar and a significant percentage of dark silicate minerals are typically classified as basaltic rocks. These rocks have a composition that is intermediate between mafic and felsic rocks, with a silica content of around 50-60%. Basaltic rocks often form from the solidification of magma with a basaltic composition.

The Lunar Highland rocks reflective and anothositic in composition, while the Lunar Maria are less reflective and basaltic in composition.
Andesite and diorite are two common igneous rocks that have a mineral composition intermediate between granitic and basaltic rocks. Andesite is fine-grained and contains plagioclase feldspar and pyroxene minerals, while diorite is coarse-grained and composed of plagioclase feldspar, amphibole, and other minerals.
magma can be classified into two,magma of granitic composition(originates from lower continental crust) and magma of basaltic composition (which originates from upper mantle).Both can form intrusive rocks.
Granite igneous rocks are lighter in color than basaltic rocks primarily due to their mineral composition. Granite is rich in light-colored minerals such as quartz and feldspar, which contribute to its lighter hues. In contrast, basaltic rocks contain a higher proportion of dark-colored minerals like pyroxene and olivine, resulting in their darker appearance.

The opposite of basaltic is rhyolitic. Basaltic rocks are formed from lava that is low in silica content, while rhyolitic rocks are formed from lava that is high in silica content.
