Soil moisture is the water that is held in the spaces between soil particles, generally in the upper 10 cm of soil. Although soil moisture is just a fraction of the total water mass in the water cycle, this small amount of water plays a critical role in evaporation and plant transpiration proces
The Hydrosphere is associated with water in the liquid state, which covers about 70% of the Earth's surface. Most liquid water is found in the oceans.
Two characteristics of climate change are resulting in sea level rise. First, the melting of ice sheets and glaciers on land are adding more water to the oceans.
The Cryosphere refers to any place on Earth where water is in its solid form, where low temperatures freeze water and turn it into ice. The frozen water can be in the form of solid ice or snow and occurs in many places around the Earth.
