True. The Earth has a limited amount of water. While water is a renewable resource through the water cycle, the total amount of water on Earth remains relatively constant. The water on Earth circulates between the atmosphere, land, and oceans, but it does not increase or decrease significantly over time. Therefore, it can be considered finite or limited.
