The Earth’s climate system is composed of five components, namely Atmosphere, Hydrosphere, Solid Earth, Cryosphere, and Biosphere. The Atmosphere is the gaseous layer that surrounds the Earth, consisting of nitrogen (78%), oxygen (21%), and other gases such as carbon dioxide and water vapor. The Hydrosphere is the layer of liquid water that covers the planet, including oceans, lakes, rivers, and groundwater. The Solid Earth is the layer of rock, soil, and sediment that covers the surface of the Earth and is the foundation of the planet. The Cryosphere is the frozen water component of the Earth system, including frozen ground (permafrost), glaciers, ice caps, ice sheets, and sea ice. The Biosphere is the layer of life on Earth, including plants, animals, and microorganisms.

Therefore, Option B. Solarsphere is not included in Earth's climate system. The Solarsphere is the outermost layer of the Sun's atmosphere and consists of three distinct regions: the Photosphere, the Chromosphere, and the Corona. The Photosphere is the most visible region of the Sun's atmosphere and is the source of most of the Sun's radiation. The Chromosphere is the region of the Sun's atmosphere that lies just above the photosphere and is characterized by a reddish-orange color. The Corona is the outermost region of the Sun's atmosphere and is characterized by extremely high temperatures and an ethereal glow.

Therefore, Option B. Solarsphere is not included in Earth's climate system.

Key Points:
• The Earth’s climate system is composed of five components, namely Atmosphere, Hydrosphere, Solid Earth, Cryosphere, and Biosphere.
• The Solarsphere is the outermost layer of the Sun's atmosphere and consists of three distinct regions: the Photosphere, the Chromosphere, and the Corona.
• Option B. Solarsphere is not included in Earth's climate system.
