Four major parts of Earth work together as a complex system: rocks, water, air, and life. On a global scale, each part can be thought of as a sphere, roughly the same size and shape as the planet. The four parts are called the geosphere, hydrosphere, atmosphere, and biosphere.Click to see full answer. Also question is, what are the 4 layers of the geosphere?The geosphere has four layers: the crust, the mantle, the inner core and the outer core. The geosphere is not homogeneous. Earth is a oblate spheriod.Also Know, what are the four major components of the Earth’s life support system? Earth’s Life-Support System Has Four Major Components The earth’s life-support system consists of four main spherical systems that interact with one another—the atmosphere (air), the hydrosphere (water), the geosphere (rock, soil, and sediment), and the biosphere (living things). Hereof, what are some parts of the geosphere? The three parts of the geosphere are the crust, the mantle, and the core.Why is the geosphere so important?The Geosphere is important because it defines much of the environment we live in, controls the distribution of minerals, rocks and soils and generates natural hazards that shape the land and impact humans.
