What rock forms from light-colored lava?
Rhyolite is a common rock that forms from light-colored lava. It is composed mainly of silica-rich minerals such as quartz and feldspar, giving it a light color. Rhyolite has a fine-grained texture and often contains small crystals.
What rock in the igneous family are medium colored and have no silica?
Igneous rocks that are medium colored and have no silica are called mafic rocks. They are mainly composed of magnesium and iron.
What does gabbro look like?
Gabbro is a dark-colored intrusive igneous rock that is composed mainly of pyroxene and plagioclase feldspar. It typically has a coarse-grained texture and can appear black, greenish-black, or dark gray in color. It can have a speckled appearance due to the presence of light-colored minerals like feldspar.
Which igneous rock is dark colored cooled rapidly on earths surface and is composed mainly of plagioclase feldspar olivine and pyroxene?
scoria
High level clouds that are mainly composed of ice crystals?
Cirrus clouds are high-level clouds that are mainly composed of ice crystals. These wispy clouds form at altitudes of 20,000 feet or higher and are often indicators of fair weather. Cirrus clouds are thin and feathery in appearance, giving the sky a streaked or wispy look.
What does primarily composed mean?

What are wine crystals and how do they form in a bottle of wine?
Wine crystals are harmless sediment particles that can form in a bottle of wine. They are mainly composed of tartaric acid and potassium bitartrate. These crystals form when the wine is chilled, causing the tartaric acid to combine with potassium to create solid crystals. They are natural and do not affect the taste or quality of the wine.
What color is substratum?
The substratum is located below the subsoil. It is mainly composed of medium-sized rocks, usually sediments and Aeolian deposits, and light-colored soil.
What is the sun composed of mainly?

What is the size of crystals in granite?
Crystals in granite can vary in size, but typically range from 1 mm to several centimeters in diameter. The size of crystals is influenced by factors such as the rate of cooling of the magma and the mineral composition of the granite.
The protein fibers of the bone matrix are composed of?
The protein fibers of the bone matrix are mainly composed of collagen, which provides strength and flexibility to bones. These fibers are embedded in a mineralized matrix made of calcium and phosphate crystals, which contribute to the hardness and rigidity of bones.
What is air mainly composed of?
Nitrogen
