Answer:
C). Corundum
Explanation:
Corundum is a crystalline type of aluminum oxide that usually contains iron, titanium, vanadium and chromium traces. Corundum is an incredibly durable and hard material. It is the third hardest mineral, after moissanite and diamond.
A geologist determine that a sample of a mineral can’t be scratched by a steel naill but can be scratched by a Masonary drill bit. Based on this information, the sample mineral has to be softer than CORUNDUM.
Due to Corundum's hardness , it can scratch almost every other mineral, and Since corundum is harder than the drill bit of masonry that can smash the mineral sample and thus the mineral sample must be softer than corundum.
The answer is - wind.
Wind is the most commonly used term for air movement. It is created when there's two air pressures with different values, the air that has a higher pressure always moves towards the air that has lower pressure, thus creating air movement or wind. Depending on the difference in the air pressure between the two air masses we can have winds that are very strong, standard winds, or very slow winds. The bigger the difference between the air pressures the stronger the wind is, the smaller the difference in air pressures the slower the wind is.
