Water vapor is also released from the Earth's interior by volcanoes. The science community now generally agrees that the Earths climate is undergoing changes in response to natural variability, including solar variability, and increasing concentrations of greenhouse gases and aerosols. The Water Cycle and Climate Change. How much water does Earth have? https://www.michiganseagrant.org/lessons/lessons/by-broad-concept/ That direction has changed drastically due to changes in water mass on Earth.

In addition to gauging changes in water mass on the Earth's surface, GRACE can detect large-scale moisture changes underground. For example, liquid water from the seas evaporates into the atmosphere, and the atmosphere precipitates water back down to earth. This fascinating book explains how the shape of Earth is changed by weathering and erosion--the breaking down of rocks and minerals which are then carried from one place to another by water, ice, wind, and gravity.
