GEOLOGY

Detailed explanation-1: -Key Concepts. Density is a measure of how heavy something is compared to its size. If an object is more dense than water it will sink when placed in water, and if it is less dense than water it will float.

Detailed explanation-2: -In the case of water, an object with a density less than 1 g/cm3 will float. The closer its density is to 1 g/cm3, the more of it will sit below the water level. An object with a density of 0.5 g/cm3 will sit half in and half out of the water. Three-quarters of an object with a density of 0.75 g/cm3 will be submerged.

Detailed explanation-3: -The positioning of molecules affects the density of an object. Objects with tightly packed molecules are more dense than those where the molecules are spread out. Density plays a part in why some things float and some sink. Objects that are more dense than water sink and those less dense float.

Detailed explanation-4: -The heavy materials or substances sink to the bottom of the water solution. Example: Copper, silver, gold, sand, and chalk powder.
