  2. ATMOSPHERE • The Atmosphere surrounds the Earth and is the outer sphere. It is formed by a mixture of gases , called air

  3. HYDROSPHERE • The Hydrosphere is all the water on the Earth, and covers three quarters of our planet.

  4. GEOSPHERE • c. The geosphere is the solid sphere. It is formed by mineral rocks and metals. It has three layers: The curst. It is the outer layer. It is formed by a mixture of rock with lower density. • The mantle. It is the intermediate layer. It is formed by rock with medium density. • . • Core. It is a mixture of iron and nickel, materials with the highest density. The temperature is very high.

  5. BIOSPHERE • The biosphere is the living beings which inhabit the Earth and live in the three other layers.

  6. NATURAL RESOURCES • The natural resources are matter or energy taken from the layers of Earth. These resources can be renewable or non-renewable: • • Renewable resource. Are replenished by natural processes • Inexhaustible renewable resources • Renewable resources that can regenerate • • Non- renewable resource. Their consumption rate is higher than their regeneration rate.
