Conglomerate, a type of sedimentary rock, is made of rounded grains that are all the same size. The rounding of the clasts indicates that they have been transported some distance from their original source.

∙ 14y agoOne type of rock that is composed of spherical grains is Oolite /
Oolitic limestone. The individual grains are known as ooids or ooliths.
The grains are formed in shallow warm seas with a high tidal range that are super saturated with calcium carbonate (or other minerals). The calcium carbonate precipitates around a nuclei (commonly a quartz grain or shell fragment) and ultimately forms a series of concentric layers resulting in the Ooid's spherical geometry.

Which rocks has two different size grains of the same mineral?
The rock is conglomerate. The other rock would be Breccia if its grains were not rounded.
What kind of sedimentary rock is made of fragments of rocks cemented together by a mineral?
Breccia is the type of sedimentary rock that is made of other fragmented rocks. The mineral that holds the fragments together can be made from the same rock material as the larger fragments, or from a different type of rock entirely.
What general rock feature does a geologist look for in a sedimentary rock to determine the distance the rock has traveled from its place of origin?
I think you might be referring to what is called textural maturity. It is assumed that a rock with high textural maturity has traveled a longer distance, as high maturity corresponds to more processes acting on the sediment and a longer time between erosion and deposition. Features to look for to determine maturity are grain size sorting, angularity/roundedness, and composition purity. Same-sized grains, round grains, and a single mineral type all indicate high textural maturity (this sediment forming this rock traveled far). A wide range of grain sizes, grains that are jagged, and a lot of different mineral grain types, all point to low textural maturity (this rock formed near it's source). And you can have combinations inbetween.
How is igneous sedimentary and metamorphic rock the same?
Sedimentary is formed by the sediments collecting, compacting and cementing together. Metamorphic rocks are made when rocks are compacted and exposed to heat and pressure. The only rock that is made of cooled hardened magma is an igneous rock which can be made two ways, intrusively or extrusively.
Are crystals the same as rocks?
Crystal and gemstones are different. Gemstones have different chemical compositions like Diamond or Sapphire.

Are all sand grains made up of the same materials?
No. Sand grains could be a mixture of particles of all sorts of different rock grains. Some sands are mostly quartz grains, some are grains of feldspars, some are gypsum, some are basaltic, and some are combinations of types. Sand can actually be formed from almost any rock type.
Why does granite stay the same over years?
its a sedimentary rock and contains grains

What is a rock's texture?
The texture of a rock consists of it's grain or mineral crystal size, the arrangement of the grains or crystals, and the degree of uniformity of the grains or crystals. Examples of rock texture would be: * Coarse grained--visible crystals or grains as in granite. * Fine grained--small grains, invisible to the unaided eye as in shale. * Porphyritic--large visible crystals in a fine grained matrix as in granite porphyry. * Schistose--layers of flattened micaceous minerals such as in mica schist. * Foliated--a metamorphic rock texture of parallel mineral banding as in gneiss. * Homogenous--same grain apperance in all directions as in basalt.
Is stone made out of rock?
Rock and stone are the same thing.
What are pieces of rock made from the same matter that created planets?
Common minerals like feldspars and metals are pieces of rock that are made from the same matter that created planets
Are all the moons in your solar system made out of the same rocks?
There not made with the same rock. It depends on the temperature of the planet
Is stone made of rocks?

What rock is made up of the same minerals as granite?
Rhyolite.
What is the same about rocks and soils?
soil is made up of rock therefore they have the same properties
