25,000 = 2.5 x 10^4
250 = 2.5 x 10^2
0.025 = 2.5 x 10^-2
0.00025 = 2.5 x 10^-4 :D

Answer:
Option (1)
Explanation:
Trade winds are usually defined as those wind that blows from the eastern side to the western side. These are the prevailing winds that occur between 25° N and 25° S of the equator.
In the northern hemisphere, this wind is originated from the high-pressure tropical region (northeastern direction) and moves towards the equatorial region (low-pressure zone), and in the southern hemisphere, this wind is originated from the high-pressure tropical region (southeastern direction) and moves towards the equatorial region.
This wind is commonly known as the easterlies, named after their wind originating direction.
Thus, the correct answer is option (1).
