What are facts about basalt?

Answer 1

basalt underlines more of earth surface than any other rock type . most areas within earth's ocean are under lain basalt . although basalt is much uncommon on continents, lava flows on flood basalts under lie several % of earth's land surface it is an very important rock

Answer 2

Basalt is an igneous rock that forms from the relatively rapid solidification of basaltic lavas; that is, those magmas that are relatively high in iron and magnesium, and low in silica and aluminum. These features give basalt its dark color and higher relative density when compared to silicate igneous rocks. The oceanic crust is largely composed of this fine-grained extrusive igneous rock.

Answer 3

Basalt is a fine-grained volcanic rock that is most commonly dark in color. It is the most common rock type in the Earth's crust. Basalt forms from the rapid cooling of lava flows on the Earth's surface.

Answer 4

Basaltic is a reference to magma that is destined to become basalt when cooled after eruption, or in reference to a solidified flow, rock, or structure consisting of basalt.

Answer 5

It is the most common rock in the crust of the Earth, as most of the ocean floor is composed of it.

Basalt is an extrusive igneous rock

Answer 6

A dark fine-grained volcanic rock that sometimes displays a columnar structure
