The biosphere consists of all forms of life, from single-celled organisms to pine trees to people. The interactions of Earth's other spheres - lithosphere/geosphere, hydrosphere, atmosphere and/or cryosphere and pedosphere - create the conditions that can support life. Areas of the crust where new crust is created are called divergent boundaries , and areas of the crust where it is brought back into the earth are called convergent boundaries . [16] [17] Earthquakes result from the movement of the lithospheric plates, and they often occur near covergent boundaries where parts of the crust are forced into the earth as part of subduction. [18] earth is 4.5 billion years old Water vapors and CO 2 allow the earth's atmosphere to catch and hold the sun's energy through a phenomenon called the greenhouse effect .
