Which explains the seasonal variation in the number of hurricanes that form in the atlantic? a) hurricanes rely on moisture for energy. b) hurricanes derive their energy from heat. c) hurricanes form more frequently when sea levels are higher. d) hurricanes form at lower latitudes and travel to higher latitudes.

B) Hurricanes derive their energy from heat. 

A hurricane begins with a pre-existing disturbance, an area of low pressure. Favorable conditions advances to the formation of hurricanes. The first one which greatly contributes to the seasonal variation in the number of hurricanes that form in the Atlantic is an increase in sea surface temperatures. For a tropical depression to mature into a hurricane, it requires heat energy from the ocean surface.

Cultural convergence is the theory that two cultures will be more and more like each other a very notable example of this is around the u.s.-mexico border, where
