Basalt is an extrusive igneous rock.
Basalt is an extrusive igneous rock, which means it has solidified from magma above ground. It is a mafic rock, meaning that it is relatively high in heavier element content, particularly magnesium and iron. Compared to felsic extrusive igneous rocks, like rhyolite, basalt is heavier and darker. Because of rapid cooling, basalt is composed of smaller crystals. Color ranges from greenish-black to black.
Both are igneous rock.
Basalt falls into many different categories:
Hope that helps! Basalt is often found at mid-ocean ridges and at hot-spot volcanoes, like Hawaii. It's also found on other planets: the Moon's "seas" are actually dark patches filled with basalt!

Basalt is not a metamorphic rock but an igneous rock, usually dark-colored. It is the most common type of volcanic rock on Earth.
The giant's causeway in Ireland is primarily composed of a type of igneous rock called basalt.
Shale is the type of sedimentary rock that is impermeable.
