The water cycle, also known as the hydrological cycle, plays a crucial role in affecting each of Earth's spheres (atmosphere, hydrosphere, lithosphere, and biosphere). The water cycle involves the continuous movement of water between these spheres, and it has significant impacts on various Earth processes.

Here's how the water cycle affects each sphere:

Cycling of matter and energy in the Earth system can lead to movement in the Earth's crust through geological processes such as plate tectonics. Here's how it happens:

In summary, the water cycle affects all of Earth's spheres, contributing to weather patterns, shaping landscapes, supporting life, and forming habitats. Additionally, the cycling of matter and energy in the Earth system drives geological processes like plate tectonics, which lead to movements in the Earth's crust and the formation of new geological features.

The water cycle connects the four Earth systems as; water in the hydrosphere can evaporate to become part of the atmosphere. Through precipitation, water in the atmosphere can return to the hydrosphere or percolate into the ground to become groundwater part of the geosphere. Within the boundary of the Earth is a collection of four interdependent parts called “spheres“: the lithosphere, hydrosphere, biosphere, and atmosphere. The spheres are so closely connected that a change in one sphere often results in a change in one or more of the other spheres. Water sustains life and is an important link between each of the four "spheres" of the Earth system (hydrosphere, atmosphere, pedosphere, and biosphere). Water moves through the hydrosphere in a cycle. Water collects in clouds, and then falls to Earth in the form of rain or snow. This water collects in rivers, lakes and oceans. Then it evaporates into the atmosphere to start the cycle all over again. The biosphere is all of the living things on Earth. The biosphere is an important part of the water cycle because it is where all the spheres interact and work together. Livings things depend on all of the other spheres. Especially important is when plants transpire, putting water vapor into the atmosphere. Water moves between the atmosphere and the surface through evaporation, evapotranspiration, and precipitation. Water moves across the surface through snowmelt, runoff, and stream flow. Water moves into the ground through infiltration and groundwater recharge. Underground, groundwater flows within aquifers. In the interaction between the biosphere and the hydrosphere, the biosphere requires water to drink and for the growth of plants. The water is provided by the hydrosphere. This interaction between the hydrosphere and biosphere helps life on Earth to be more sustainable. Tremendous heat and pressure within the earth cause the hot magma to flow in convection currents. These currents cause the movement of the tectonic plates that make up the earth's crust. As energy moves through an ecosystem, it changes form, but no new energy is created. Similarly, as matter cycles within an ecosystem, atoms are rearranged into various molecules, but no new matter is created. So, during all ecosystem processes, energy and matter are conserved. The constant exchange of matter and energy between Earth's spheres happens through chemical reactions, radioactive decay, the radiation of energy, and the growth and decay of organisms.
