A grain of sand is transported by wind, ice or water and then deposited and buried along with many other grains of sand, and compacted (squashed under pressure), usually at the bottom of an ocean or a lake; the squashed-together grains of sand are then infiltrated and held together by a mixture of water and a mineral such as calcite (which act as a natural cement). Sands form sandstones, which are classified as sedimentary rocks. It can take milionsof years for significant amount of sandstone to form.

∙ 13y agoIt starts off as a grain of sand and then it turns into an igneous rock. After, it turns into a sedimentary rock. When it travels down the asthensophere and up through the volcano, the sedimentary rock melts and it cools into an igneous rock. After weathering and erosion, it is sedimentary rock again. Then after more weathering it is made much smaller and is finally sand :)

What types of grains is sedimentary rock made from?
sand grains
Are rocks made from sand?
it depends what type of rock you have really, if you have a rock with crystals in it wont have sand in, if you have a pourous rock it wont have sand in either, but if you have a rock with grains you may find sand in the rock! Answered by a 12 year old lolz +++ Pretty much right - well done! You do have certain types of rocks ('sedimentary rocks') with sand in them, formed from earlier deposits of sand; but the sand itself is grains of hard minerals remaining from harder rocks that have been eroded away. So the rock with crystals does not have sand in it, but when weathering breaks that rock down, the crystals are left as grains of sand.
What are most grains of sand made of?
tiny broken down pieces of rock and sea shells
What is a rock that is made up as pebbles and sand grains that have been cemented together?
Conglomerate; a clastic sedimentary rock composed of rounded pebbles and sand cemented together.
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.

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.

Is sand desert sand a nonliving thing?
Yes. Sand consists of tiny grains of rock. Rock is not alive.
Were sand dunes made by glaciers?
No. Sand dunes are typically made by the wind, blowing lightweight grains of sand and soil. Glaciers created several types of landforms, including moraines and drumlins, out of a wide range of particle sizes, from rock grains to boulders.

What are standstones made of?
Sandstones are made out of sand sized particles or rock grains. Sandstones are clastic sedimentary rock. Some sandstone is composed of feldspar or quartz.
What are the grains of a rock-?
Grains: Grains that are not crystals in rock do not have flat shiny faces. They are rounded, like grain of sand, or jagged, like a piece of broken rock. Grain Size: Grain size in rocks can mean the size of crystal grains or of fragments: Coarse Grained: most of the rock is made of grains as largeas rice, or larger.
