Question

In sedimentation , the upper layer of liquid is called _______and the heavier layer at the bottom is called _________.

Answer 1

Answer:

Explanation:

The process of separating insoluble substances which are heavier than liquid by allowing them to settle down on their own due to gravity is called sedimentation. The particles which settle down during sedimentation are called sediments.

pls mark my answer as the brainliest and give many thanks

Answer 2

In sedimentation , the upper layer of liquid is called  supernatant and the heavier layer at the bottom is called sediment.

Explanation:

• Sedimentation is the process of separating insoluble substances that are heavier than liquid ,It is allowed to settle down based on the gravity.
• Sediments are the particles which settle down during  the process of sedimentation.
• Supernatant liquid is the clear liquid above the sediment.
• If the supernatant is transferred to a separate container without disturbing the sediment a clear solution is obtained.
• In sedimentation, the sedimentary rocks, waste or dirt particles are allowed to settle down in the bottom of the container.
• The upper layer of water which is free from dirt particles is in next step are then slowly passed to another beaker impurities, This process of separating the impurities from the liquid is called decantation.
