rocks are formed from grains and grains are small and the rocks are big. Sedimentary rocks are formed when grains or sediments are compacted together.

Rocks are composed of one or more minerals, while grains are small, individual particles of a mineral. Rocks can be made up of different types of minerals and have a variety of sizes and shapes, while grains are typically uniform in composition and size. Rocks are larger and can be made up of multiple grains, whereas grains are individual, tiny fragments.

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?
No, porous rocks are rocks with small holes or spaces that allow fluids or gases to pass through. Rocks formed from grains stuck together are sedimentary rocks, such as sandstone or limestone.
Different types of metamorphic rocks are distinguished by the?
Different types of metamorphic rocks are distinguished by the minerals present, the degree of metamorphism they have undergone, and their texture or fabric. Texture refers to the size, shape, and arrangement of mineral grains within the rock, while the degree of metamorphism can range from low-grade (such as slate) to high-grade (such as gneiss).
What G are the small bits that rocks are made from?
The small bits that rocks are made from are called grains. These grains can vary in size and shape, and are typically composed of minerals or other solid materials.
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 as small as grains of salt are called sand.
Why do some sedimentary rocks contain rounded grains and some not?

Factors like the energy of the transporting agent and the distance traveled can influence the roundness of the grains in sedimentary rocks.
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.
Why do rocks have grains?
Rocks have grains because they are made up of different mineral particles that have been compacted or cemented together over time. These mineral particles can vary in size, shape, and composition, creating the overall texture and appearance of the rock.
