Test: Methods of Separation in Everyday Life - Class 6 MCQ

 Churning involves agitation to separate components in a liquid mixture based on their density or other physical properties. In the context of churning, lighter components, such as cream, can be separated from heavier components, such as buttermilk, by the mechanical agitation of the mixture.

Here's a quick rundown of the other methods you listed:

1. Magnetic separation: This method uses magnets to separate magnetic materials from non-magnetic ones.
2. Sedimentation: This process allows heavier particles to settle at the bottom of a liquid over time due to gravity.
3. Winnowing: This technique involves separating lighter components from heavier ones by using air flow, commonly used in agriculture to separate grain from chaff.

So, for separating lighter components from heavier ones using agitation, churning is the correct choice.
