Pour the mixture through a kitchen sieve. The gravel will remain in the sieve the water can be collected in a bucket or another container.
The water in the gravel increases the weight.
Gravel does not absorb water as much as soil. Gravel has larger pore spaces and lacks the fine particles that help retain water, so water tends to flow through gravel more easily. Soil, on the other hand, has small pores that can hold and retain water.
if you mean how can we separate sand from gravel we should use separator .for a low amount manually and huge amount mechanical separator. In labs you can use shaker and mesh with different rank.
Water will travel faster in gravel than sandStudents in secondary school should know this!
separate them by making two diffrent piles
You can use a coffee filter in first than put your water in than the gravel and that is how you separate gravel and water...:) or you can get a screen like a drainer and pour all of your gravel and water in that.....:)
BOil the solution then filter it out

1. Put the mixture of gravel and salt in water. 2. Salt is water soluble, gravel not. 3. Filter: the salt is in the solution.
Salt is soluble in water; gravel is separated by filtering the solution or by decantation.Power is not a material.
I would add enough water to dissolve all of the salt. Then pass it through a strainer to collect the gravel.
The gold is heavier than the gravel so water is slowly swished until all that is left is the gold.
If you think about it, you can figure it out. Does one of the substances float in water and the other one sink?
First dirt, plastic, gravel are deleted by filtration. The solution is evaporated and a salt is obtained as a residue.Again add water: gravel is sedimented in water, plastic floats and both can be separated; dirt is separated by a new filtration.
If we need to separate sand and gravel, we simply use the size of the material and a mechanical contraption to do the separating. A screen with mesh of the proper or appropriate dimensions will sieve the particles nicely. The sand will fall through the mesh piling up underneath it, and, if the screen is tilted, the gravel will bounce its way down and off the screen into a separate pile.
No, it does not.
