The properties of the original elements are completely changed.
For example, in the compound called "iron(II) sulphide", it is composed of iron and sulphur, that are chemically combined together. The element iron is attracted to magnets. Meanwhile, iron(II) sulphide is not attracted to magnets.
Another example is where sulphur has a yellow colour, but iron(II) sulphide has a brownish colour. As we can see, even the physical properties (colours) are completely different.
Therefore, the properties of the original elements are completely changed when they're combined into compounds.
Everything in the universe was created when the Big Bang occurred and the universe is expanding
Iceberg: The formation of icebergs increases salinity because it is taking liquid water out of the ocean without taking the salt.
Sea Ice: Same as icebergs, this increases salinity because it removes liquid water.
Runoff: This decreases salinity because it is introducing fresh water into the ocean, reducing the salt to water ratio.
Evaporation: This would increase salinity because it is removing liquid water from the ocean, increasing the salt to water ratio.
Hope this helps!
