Are rocks made from sand

Answer 1

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.

Answer 2

Rocks are not typically made directly from sand. Sand is a grain size classification of sediment, whereas rocks are formed from the lithification (compaction and cementation) of sedimentary materials or from the cooling and solidification of molten materials like magma or lava. Sand can be a component of sedimentary rocks if it becomes compacted and cemented together over time.

Answer 3

Oddly enough, rocks can be made from sand (sandstone), and sand can be made from rocks, through weathering.

Answer 4

Yes it is made of rocks which are been broken down through erosion and weathering, and primarily grains of Quartz as this is highly resistant.
