The solar cycle or solar magnetic activity cycle is the nearly periodic 11-year change in the Sun's activity (including changes in the levels of solar radiation and ejection of solar material) and appearance (changes in the number and size of sunspots, flares, and other manifestations).
Planet earth is generally thought of a composed of the atmosphere, the hydrosphere, the lithosphere and the biosphere. The geosphere is often used to mean the same thing as lithosphere - rocks and stones. If this is how you are using the word, then the geosphere consists of the crust, the mantle and the core. Comments.
The five components of the Earth's climate system are the atmosphere, the biosphere, the cryosphere, the hydrosphere, and the geosphere. The atmosphere includes the gases and water vapor that form a thin insulating blanket over Earth's surface. The biosphere is the living portion of Earth's surface that includes all living organisms. The cryosphere includes all the frozen water on Earth's surface, such as ice sheets, glaciers, and floating sea ice.
