This diagram is missing labels!  Where should the correct labels go?

• Black arrow="Cold Air" because less dense air is rising
• White arrows="Hot Air" because less dense air is sinking
• White arrows="Cold Air" because more dense air is sinking
• Black arrow= "hot air" because more dense air is rising

A hurricane forms over the Atlantic Ocean. When it hits land and comes ashore, its wind speed decrease significantly.  This happens because the hurricane:

• gains more water from the flooded land than the ocean
• meets a land breeze
• meets a stronger hurricane moving from land
• no longer gains energy from warm ocean water
