All the spheres interact with other spheres. As, rain (hydrosphere) falls from clouds in the atmosphere to the lithosphere and forms streams and rivers that provide drinking water for wildlife and humans as well as water for plant growth (biosphere). The rock cycle affects Earth by recycling many of the rocks that were first on Earth when it began. The rock cycle is the changing of one rock type to another, typically caused by pressure, heat, or erosion. Depending on location, rocks can change from one form to another within a day or require thousands of years.These four system are constantly interacting between each other. The biosphere needs water (hydrosphere) in order to survive. The biosphere needs gases (atmosphere) like for example the animals needs oxygen as a fuel for the cells to function and survive. These four systems are constantly interacting between each other. The biosphere needs water (hydrosphere) in order to survive. The biosphere needs gases (atmosphere) as the animals needs oxygen as a fuel for the cells to function and survive. When a parcel of air in the atmosphere becomes saturated with water, precipitation, such as rain or snow, can fall to Earth's surface. That precipitation connects the hydrosphere with the geosphere by promoting erosion and weathering, surface processes that slowly break down large rocks into smaller ones. The biosphere needs water (hydrosphere) in order to survive. The biosphere needs gases (atmosphere) like for example the animals’ needs oxygen as a fuel for the cells to function and survive. Atmosphere has ozone layer which protects living things from dangerous radiation from the sun. Plants in the biosphere absorb carbon dioxide from the atmosphere during photosynthesis and release oxygen. The hydrosphere, which includes all water on Earth, provides necessary water for life in the biosphere and also influences the atmosphere by absorbing and distributing heat.
