The correct answer is option 4: 1, 2, and 3.
Statement 1 is correct. A hurricane acquires its spin from the Coriolis effect. The Coriolis effect is caused by the rotation of the Earth, which causes moving air or water to be deflected to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. This deflection creates the spin in a hurricane.
Statement 2 is correct. The diameter of a hurricane decreases as it moves away from low latitudes. Hurricanes thrive in warm ocean waters near the equator, where there is a large supply of heat and moisture. As a hurricane moves away from the equator, it enters areas with cooler ocean temperatures and less favorable atmospheric conditions, causing it to weaken and decrease in size.
Statement 3 is incorrect. The diameter of a hurricane can vary greatly, and there is no minimum size requirement. Some hurricanes can have diameters less than 150 km, especially if they are in their early stages of development or have weakened significantly.
Therefore, option 4: 1, 2, and 3 is the correct answer.
