Question

Hurricanes dissipate when_______

O they move over colder ocean water.
O they move over land.
O surface inflow of air exceeds upper-level outflow of air.
O all of the above are correct.

Answer 1

Hurricanes dissipate when all of the following conditions apply: they move over colder ocean water, move over land, or when surface inflow of air exceeds upper-level outflow of air. These factors disrupt the hurricane's fuel source and internal balance, leading to its dissipation. The correct answer is option 4.

Step-by-step explanation:

Hurricanes dissipate when they experience conditions that are not conducive to their development or sustenance. This can happen in several situations:

• They move over colder ocean water, which can deprive them of the warm, moist environment they need to maintain their strength.
• They move over land, where the lack of warm ocean water and increased friction can lead to a rapid decline in their power.
• Surface inflow of air exceeds upper-level outflow of air, disrupting the hurricane’s internal pressure and wind systems.

Therefore, the answer is 'all of the above are correct.' Hurricanes rely on specific atmospheric conditions, and when those are not present, the system falls apart.
