Penny stated that the water in an iceberg will eventually become the water that falls in an area as rain. Why is this?
A.) Icebergs contain crystallized water that can be swept by the wind into clouds, where it melts to form rain.
B.) Icebergs release water vapor to the environment through transpiration, and this water eventually forms rain clouds.
C.) Icebergs release water to the ocean as they melt, and this water is evaporated by the sun into the atmosphere, where it forms rain clouds.
C.) Icebergs release water to the ocean as they melt, and this water is evaporated by the sun into the atmosphere, where it forms rain clouds.
