What else can I help you with?
Are scoria and rhyolite the same in mineral composition?
Rhyolite is a rock type that is categorized by mineral composition. Scoria is a textural rock type. Like, Rhyolite can be smooth, or it can be scoria (sharper, bumpier, lots of vesicles).Think of it as a rock adjective.
How is the size of the mineral grains affect by the rate at which molten rock material rock?
The slower the rate of cooling the larger the size of the crystals that can develop.
What is a rock with long flat mineral grains?
A rock with long flat mineral grains is likely to be schist. Schist is a metamorphic rock characterized by its foliated texture, with mineral grains aligned in a parallel fashion, giving it a distinct layered appearance.
What kind of sediment consists primarily of mineral grains that were eroded from rocks on land?
Detrital sediment consists primarily of mineral grains that were eroded from rocks on land. These mineral grains are transported by wind, water, or ice and eventually settle and accumulate to form detrital sedimentary rocks, such as sandstone or shale.
What rock has large mineral grains?
Fine grains of rocks are referred to as "clasts." The word "clast" comes from the Greek word "klastos," meaning "broken."

Does scoria have crystals or grain size?
Scoria typically has a vesicular texture with small gas bubbles, giving it a lightweight and porous appearance. It generally lacks visible crystals and instead features a glassy or fine-grained matrix. The grain size is usually very small, often classified as aphanitic, meaning the individual mineral grains are not easily distinguishable. Overall, scoria's texture is more characterized by its vesicles than by crystal size.
Does pumic have mineral grains?
Pumice does not have grains.
How is the size of the mineral grains affect by the rate at which molten rock material rock?
The slower the rate of cooling the larger the size of the crystals that can develop.
When water combines with mineral grains do the grains become smaller or larger?
When water combines with mineral grains, the grains can become smaller due to mechanical weathering processes like abrasion and attrition, where the movements of water cause the grains to break down into smaller pieces. However, in some cases, water can also facilitate processes like dissolution or precipitation that can lead to mineral grains growing larger.
What kind of mineral has a large grains?
Intrusive
What is a rock with long flat mineral grains?
A rock with long flat mineral grains is likely to be schist. Schist is a metamorphic rock characterized by its foliated texture, with mineral grains aligned in a parallel fashion, giving it a distinct layered appearance.
What is scoria's hardness?
Scoria, is a poor-quality glassy substance formed in volcanoes. It commonly has many gas vesicles in it, and is usually red to black in colour. Unlike its cousin Pumice, scoria has a density greater than 1, hence it will sink in water. As to melting point, like most complex mixtures it does not have a simple melting point, rather a softening point, and this will be in the high hundreds of deg C.
What is a banded mineral?
A banded mineral is a mineral that has grains that are arranged in a particular pattern of flat layers or forms swirls.
Is sandstone a mineral?
No. Sandstone is not a mineral, it is a rock type.
Is scoria nutritious?
No. Scoria is rock. It is inedible.
Are basaltic scoria and scoria the same thing?
Not necessarily. Most scoria is basaltic, but some can be andesitic.
