Cream can be separated from milk by either centrifuging or by allowing whole milk to stand. Both methods work on the principle that cream is lighter than milk.
Because cream is lighter than milk, it rises to the top when the milk is allowed to stand. The cream can then be removed by skimming the top layer off.
In layman terms, traditionally, cream is separated by allowing the milk to rest and when the cream is accumulated on top, it is skimmed off either with a ladle, or, in some countries such as US, by using a traditional hand driven separator.
At homes, raw milk is first boiled before being allowed to rest in open or in a refrigerator, and then accumulated cream is simply skimmed off with a spoon or ladle.
In modern commercial dairy farms, mechanized or computerized separators are used, which churn milk in large quantities and separate the cream from milk, and the whole process is semi or fully automated.
There are some good videos on YouTube as well.
Because the cream contains higher fat percentages. And it thickens the milk which makes it less easy to use as a cooking supply.
This is usually done with a centrifuge cream separator.

Cream, composed mainly from fats is separated from milk by centrifugation.
Fresh cream is separated from whole milk. Cream contains fat (saturated, polyunsaturated and monounsaturated fat), cholesterol, sodium, potassium, carbohydrate, vitamins A, B-12, B-5, D, C, and calcium, iron and magnesium

Cream is separated from whole milk. The main ingredient of interest in cream would be the butterfat. The amount of butterfat would depend upon the type of cream.
Fat free milk comes from a factory that has separated the fat out of the milk with a centrifuge. The fat is used to make cream.
Cream is separated from whole milk by centrifuge or gravity. If you have unhomogenised milk, leave some to stand in the fridge and remove the cream from the top of the container the next day. Milk that has been homogenised will not give much cream in this way. Raw milk would work well.
The density changes due to differences in the density between cream and milk. Cream is lighter than water and milk is heavier than water. The average density of whole milk could be close to 1.024g per liter. When the cream is removed, the density of the milk goes up to about 1.036g per liter, while the density of the cream is about 0.968g per liter.
Cream comes from mammals, mostly cows, but also goats, camels, llamas, yaks and sheep among others. Cream is milk fats that can be separated from milk simply by allowing it time to rise to the surface then skimming it off the milk. Cream is often churned to make butter as well.
Whipped cream is not made directly from milk, and it is not possible to make whipped cream with homogenized milk purchased at supermarkets. Milk will froth and foam, but it does not have enough fat to form whipped cream. One needs heavy cream to make whipped cream. Heavy cream is separated from non-homogenized milk. When fresh milk is left to stand, the cream will rise to the top, where it can be skimmed off. This cream is further concentrated into the "heavy cream" or "whipping cream" that can then be whipped into whipped cream.
Milk does not have oil in it; but it does contain animal fat. There are ways to remove the natural animal fat that occurs in milk which is where you get 2% milk and skim milk from. The fat can also be separated to make cream and butter.
milk is a mixture
