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.
How do you separate a mixture of sand and iron filings?
By using a magnet to separate the iron filings, you'd be left with the sulfur and sand mix. Selecting a solvent for the sulfur will allow you to dissolve the sulfur, and then all you have to do is put the sand in a filter and wash the sulfur through with the solvent.
How many grains of sand are on blackpool beach?
its another questoin where you never know but i know there are over a trillion grains of sand on any sort of beach.
What process causes sand grains to form a sandstone?
Sand consists mainly of silicon dioxide, and this has a great propensity to crystallize. Sufficiently so, that in extreme circumstances actual cm-sized crystals made of sand grains are known. Sand crystals by name. In any event, because of its propensity to crystallize, SiO2 grains aggregate to form a coherent whole. This is accelerated if the sand body is subject to heat, or if it is immersed, thus making chemical bonds more easy.
Is sand a sedimentary rock or is lots of sand joined together a sedimentary rock?
Sand is composed of small loose particles of eroded rock of any type, but commonly it is particles of quartz from igneous or metamorphic rock. Each sand grain is actually a rock unto itself. Only when the sand grains are cemented together through a process known as lithification, do the sand grains become part of a new sedimentary rock.
Why do sand dollars move?
Because they are like any other sea creature (espically starfish) they are living with small polyps that cling on to things and then pull themselves wherever they want to go. The sand dollars then die and leave a skeleton that people use as decorations.

What is sedimentary rocks made of?
Sedimentary rocks are made out of sediments.
How does cling film work?
Sans any research, I believe the "cling property" has to do with electron attraction to a positive (+) charge from the food wrapped.
What is sandstone made up of?
Sandstone is made up of lightly compacted or cemented grains of sand. It should feel gritty to the finger and the grains should be visible. The grains will be mainly silica grains. [Finer grained material would be a siltstone, of which slate is a metamorphosed variety. ]
How do you separate iron filings from lead filings?
Iron is a ferrous material, and aluminum is non-ferrous. A magnet would separate the two materials as the iron would be attracted to the magnet while the aluminum filings would not. The term ferrous basically refers to any material which contains iron.
Is magnetism a physical change?
yes because any that you do in magnet it is magnet again'
