Basalt has a reddish brown streak. It is a dark and dense igneous rock of a minor lava flow.
Flint in its natural state appears as a hard, dense rock with a smooth, glassy texture. It is typically dark grey or black in color and can have a shiny appearance.
Porous volcanic rock is commonly classified as either pumice or scoria. Pumice is often lighter in color and has a very porous texture due to the presence of numerous gas bubbles, while scoria is darker and similarly porous but is typically more dense than pumice. Both are formed from volcanic eruptions and can float on water.
A volcanic arc is a chain of volcanoes which form in a curved shape. They are formed when a more dense oceanic plate collide with less a dense one.

Penguins appear black due to their dense coat of feathers that are actually dark blue or gray in color. This coloration camouflages them when swimming in the ocean against predators looking up from below.
The term for high volume high velocity turbulent ultra dense black smoke is "pyrocumulonimbus." These clouds form from intense wildfires or volcanic eruptions, creating a dangerous and rapidly spreading smoke plume that can reach high altitudes in the atmosphere.
Igneous rocks typically contain high levels of silica, with compositions ranging from about 45% to over 70% silica. This silica content influences the overall properties of igneous rocks, such as their color, density, and volcanic activity. Rocks with higher silica content are generally lighter in color and less dense, while those with lower silica content are darker and denser.
Ebony is a dense black wood and the word is often used to describe something that is very black in color. Dark-skinned girls are often called 'ebony girls'.
