Answer: wind flows from areas of high to medium pressure at the earth's surface.
Explanation:
Pressure pattern drive wind pattern which in turns drives oceanic pattern.
Wind at the surface of the Earth flows from areas of high to medium pressure. The wind speed is determined by difference in barometric pressure between the linear distance and air columns over which the transition takes place.
Answer:
d) Principle of Conservation of Matter
Explanation:
Principle of Conservation of Matter -
According to the law of conservation of matter, matter is the substance which ac not be created and even it can not be destroyed , hence we need to have the same number of atoms before and after the reaction constant during a chemical change or process of chemical as were number of atoms and type of atoms present before the chemical change .
Hence , from the options , the correct answer is the Principle of Conservation of Matter .

Answer:
a. three directions at ~90°
Explanation:
Galena is known for its presence in all types of rocks (igneous, metamorphic and sedimentary rocks). It is predominantly ore of lead which has a chemical configuration of PbS and lead sulfide. Also, newly severed chunks of galena display excellent cleavage in three directions at ninety degrees.
Hence, in this case, the correct answer is "galena’s cleavage is best described as three directions at ~90°"
