The hydrosphere includes:
- Oceans
- Lakes
- Rivers
- Groundwater
The cryosphere includes:
- Glaciers
- Ice sheets
- Sea ice
- Frozen ground
The hydrosphere and cryosphere are closely connected. Water moves between the two systems in a continuous cycle. This cycle is driven by the sun's heat.
The hydrosphere-cryosphere is important for life on Earth. Water is essential for all living things. The cryosphere helps to regulate the Earth's climate by reflecting solar radiation back into space.
The hydrosphere-cryosphere is changing due to climate change. The Earth is warming, which is causing the glaciers and ice sheets to melt. This is leading to sea level rise and changes in the water cycle.
The changes in the hydrosphere-cryosphere are having a major impact on the Earth's ecosystems and on human society.
