How can you tell if a rock made of small grains is igneou or sedimentary?

Look for signs of banding or layering that would be evidence of sedimentary strata. Banding also occurs in metamorphic rocks, but the bands may be very distinct in color from one another. If the rock scratches with a knife, it may be sedimentary. High silica content in some igneous rocks may prevent scratching with a knife blade.

What types of grains is sedimentary rock made from?
sand grains
Where are rudites?
A rudite is a type of sedimentary rock. This type of rock is found along the shoreline and is made from small grains.
Is sandstone igneous or sedimentary or metamorphic?
Sandstone is a sedimentary rock which is made up of sand grains which have been compressed to form a rock that has very weak bonds holding the grains together. The grains themselves can be igneous, sedimentary or metamorphic depending on which rock the grains were eroded from.
What kind of rock has layers and is made from small grain?
That is correct. A detrital (or "clastic") sedimentary rock is formed by sediment grains that have been weathered and eroded by existing rocks and then deposited as layers.
Which two rocks are made from rounded grains?
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.

Can coarse sedimentary rock be made up of pebbles or boulders?
Yes, coarse sedimentary rock can be made up of pebbles or boulders. Coarse sedimentary rocks are formed from the accumulation and cementation of larger grains, such as pebbles and boulders, that are transported by water, ice, or wind. These larger grains are typically found in rocks like conglomerate or breccia.
What is sedimentary rocks made of?
Sedimentary rocks are made out of sediments.
What kind of rock has layers and is made from small grain?
That is correct. A detrital (or "clastic") sedimentary rock is formed by sediment grains that have been weathered and eroded by existing rocks and then deposited as layers.
Why do some sedimentary rocks contain rounded grains and some not?
Because some sedimentary rocks are made from different kinds of sediments.
Which two rocks are made from rounded grains?
Rocks that are composed of rounded grains or fragments are usually sedimentary rocks. Two of these are sandstone and conglomerate rocks.
What is a sedimentary rock made of?
small solid pieces
What are the particles in sedimentary rocks called?
Sedimentary rocks are made from particles called sediment. They are made from layers of sediment (small particles) on the bottom of rivers or seas. The sediments are compressed as more layers build on top of them. The particles then become cemented together to form solid rocks. The layers of rock are called strata. Sedimentary rocks have a grainy structure and they easily crumble.
What is marble made and slate made from?
Marble is made from metamorphosing carbonate rocks such as limestone, so it's composition is mostly calcium carbonate (like Tums, it fizzes when acid is poured on it). Slate is made from metamorphosing shale (a sedimentary rock made from small flat clay grains).
Where is limestone made?
Like most other sedimentary rocks, limestone is composed of grains; however, most grains in limestone are skeletal fragments of marine organisms such as coral or foraminifera.
