Answer:
They blow away from poles to the equator.
Explanation:
Hello,
In this case, we must take into account that global wind systems are formed by the constant increase in the temperature of the Earth’s surface. Thus, they drive the oceans’ surface currents. In such a way, we can say wind is the basic movement of air from an area of higher pressure to an area of lower pressure, for that reason they blow away from the poles to the equator.
Best regards.
<span>It's because the product formed with BF3 is more complex which able to decompose AlF3.
</span>AlF3 doesn't dissolve in HF because of the fluorine. It's doesn't allow for coordination due to the hydrogen. However, it will dissolve in KF. If you look at the chemical reaction, it's able to form a salt.

A substance undergoing thermal expansion will expand when heated, substances will mostly expand when heated but when their cold it will undergo contraction.
Mass is how much matter is in an object. Volume is how much space an object occupies. Density is the amount of mass in a volume.
Have a nice day, brainliest would be fantastic
Answer: transfer of heat by the actual movement of warmed matter
Explanation: convection is the process of heat transfer through fluids. When molecules absorbs heat they become excited and less dense causing it to rise.
