When a fluid is heated, what changes occur? it becomes more dense and begins to rise. it becomes less dense and begins to rise. it becomes more dense and begins to sink. it becomes less dense and begins to sink.

As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks.

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
