The geosphere, atmosphere, hydrosphere, and biosphere are the four spheres in which energy and matter flow. Convection is the primary mode of energy transport in the atmosphere and hydrosphere. Life on Earth is made possible by the continual cycling of matter and energy through the Earth's system. Others are driven by solar energy.
Energy and matter flow through Earth's four spheres: the geosphere, atmosphere, hydrosphere, and biosphere. Energy flows through the atmosphere and hydrosphere mostly by convection. The continuous cycling of matter and energy through Earth's system makes life on Earth possible. ... Others are driven by energy from the sun.
