Final answer:
The icecaps and glaciers near the poles contain freshwater, which is crucial for the planet's water supply.
Step-by-step explanation:
The correct answer is C. freshwater.
The icecaps and glaciers located near the poles contain a significant amount of fresh water. These ice formations are formed from layers of snow that have accumulated over thousands of years. Due to the extremely low temperatures, the snow does not melt, resulting in the formation of icecaps and glaciers.
If the icecaps and glaciers were to melt, they would contribute to a substantial rise in sea levels, as the fresh water would be added to the ocean. This would have significant implications for coastal areas and ecosystems around the world.
Therefore, the icecaps and glaciers near the poles are an important source of freshwater on the planet.
