Suspension
The word you are looking for is "sedimentation." Sedimentation is the process by which sand or particles settle out of wind or water and form layers or deposits over time.
Sediment
What this is saying relative to what you quote is that when the mixture is agitated, stirred if you will, then left without agitating, it will settle out. That means that you have to keep stirring the mixture for the particles to stay in suspension, that is to not settle out. If you put dirt into a glass of water it will settle out. If you keep stirring it will look uniform because it can't settle out. But when you stop stirring, the dirt being denser than the water will mostly settle out and given enough time most of it will settle out. But by observation means that you can see that the dirt is not settling out, which will be obvious if you have sufficient light shining on it or through it.
These particles are called sediment.
Oil and water will not mix and so will dorm district layers. It is possible to suspend oil in water by splitting it into small particles. This is called a colloid. To find out what it means, it depends on the situation. Could you clarify the question?
No. After mixing them, they settle into two separate layers (oil above the water) without any new substance formed.

Rock and soil!!
Mixtures in which some of the particles settle out are called suspensions. An example of a mixture is dirt mixed with a large amount of water. On the other hand, mixtures in which the particles do not settle out are called colloids.
The particles are heavier than water and sink instead of floating.
Heavy eroded particles settle out of moving water
the ones with the highest density
They form when heavy eroded particles settle out of moving water.
Chemicals (flocculants) are added to the water which cause the suspended pollutant particles in the water to clump together. These clumps then settle out due to gravity and are then usually removed from the bottom of the tank by mechanical means.

The small particles are compressed under water to then form sedimentary rocks
These particles are called sediment.
