Why do some sedimentary rocks contain rounded grains and some not?
Sedimentary rocks with rounded grains typically form from materials that have been transported over long distances by wind, water, or ice, which causes abrasion and rounding of the grains. In contrast, sedimentary rocks with angular grains often form from materials that have not been transported far and have not undergone as much abrasion. Factors like the energy of the transporting agent and the distance traveled can influence the roundness of the grains in sedimentary rocks.
What are the properties of sedimentary rock?
sedimentary rocks have layers showing the deposition of sediment at different time periods.sedimentary rocks consists of lots of small grains. these grains maybe weakly and together so the rocks are often porous and maybe soft and crumbly.sedimentary rocks often have fossils trapped with in them.sedimentary rocks consist of layers of lots of small particals.
Is porous a rock formed from grains stuck together?
A rock formed from grains stuck together would be Porous
What physical characteristic are detrital rocks classified?
Detrital rocks are classified primarily based on the size and composition of their sediment grains. These rocks, which are formed from the accumulation of fragments derived from pre-existing rocks, can be categorized into different types such as sandstone, shale, and conglomerate, depending on whether the grains are coarse, medium, or fine. The mineral composition and sorting of the sediment also play a significant role in their classification.
Do extrusive rocks have larger grains than intrusive rocks?
No, extrusive rocks typically have smaller grains than intrusive rocks. Extrusive rocks form from lava that cools quickly on the Earth's surface, resulting in fine-grained or glassy textures. In contrast, intrusive rocks form from magma that cools slowly beneath the surface, allowing larger crystals to develop. Thus, intrusive rocks generally have larger grains compared to extrusive rocks.
What are the three types of grains of rocks?
The three types of grains in rocks are igneous, sedimentary, and metamorphic grains. Igneous grains form from the cooling and solidification of molten material, sedimentary grains originate from the accumulation of mineral and organic particles, and metamorphic grains result from the alteration of existing rocks under heat and pressure. Each type reflects different geological processes and environments of formation.
Rough texture rocks have grains and fine textured rocks have grains?
Yes m that it true, other than glasses all rocks have grains.
Why do igneous rocks that have the same composition sometimes have different sizes of mineral grains?
This is as a result of difference in the rate of cooling of the Igneous rocks.
What are tiny rocks as small as grains of salt called?
Tiny rocks the size of salt grains are generally called, "Sand".
Where did the small grains of rocks come from?
Older rocks.

What kind of grains do rough textured rocks have?
large grains

Why are grains on the beach so small?
because sand was once rocks and the rocks got smashed to tiny grains of sand
Do lava rocks usually have large grains?
Lava rocks typically have fine to medium-sized grains due to their rapid cooling process when formed from molten lava. Large grains are less common in lava rocks than in other types of igneous rocks that cool more slowly beneath the Earth's surface.
Do igneous rocks have round grains?
No.
