Answer:
Dunes are loose sand hills.
Loess is a compacted wind-blown formation of sediment.
Explanation:
Sand dunes are, as their name implies, made of sand which is itself made of tiny quartz pieces. Sand dunes are present where there is a ready source of broken down sandstone or other type of rock and wind to transport the sand. The dunes are mobile and loose and migrate over time.
Loess comes in vast formations and was created in a very different way. In the last ice age, winds from the north carried sediments loosened and ground by glaciers southwards. There, the sediments accumulated in large formations and became compacted over time.
Explanation:
Vinegar is a sour liquid made up of acetic acid compounds. Oil is a complex non-polar chemical compound with a high amount of hydrogen and carbon in its structure.
- Vinegar is a polar acid, although a weak one.
- Generally, for a substance to mix with another one, they must be similar.
- Solubility of compounds controls miscibility.
- When two substances are miscible, they can be said to be soluble in one another.
- In solubility, like substances dissolves like substances.
- This implies that polar compounds will only dissolve polar compounds.
- Non-polar compounds will only dissolve in non-polar solvents.
- Since vinegar is polar and oil is non-polar, they will not dissolve one another.
