Sometimes, it is very windy at the beach Isabella visits in Florida. How does the high wind connect the ocean to freshwater lakes and ponds on land?

• Condensation by the wind carries

  water to the lakes and ponds

• Evaporation by the wind carries water vapor into the atmosphere to fall as rain.

• Evaporation by the wind causes saltwater clouds to form over the ocean

• High winds that accompany precipitation carry water from oceans to lakes and

  ponds.
