Unveil the Secrets of Earth's Structure and Atmosphere

1. The Earth system consists of the atmosphere, hydrosphere, lithosphere, and biosphere.
2. The atmosphere contains gases such as nitrogen, oxygen, argon, carbon dioxide, and water vapor.
3. The atmosphere has four layers: troposphere, stratosphere, mesosphere, and thermosphere.
4. The Earth's structure consists of the crust, mantle, outer core, and inner core.
5. The crust is divided into two layers: Sial and Sima.
6. Sial is thicker and less dense than Sima and is rich in silica and aluminum.
7. Sima is thinner and denser than Sial and is rich in silica, iron, and magnesium.
8. The outer core is located between 2900-5150 km from the surface and is in liquid form.
9. The inner core is located between 5150-6370 km from the surface and is in solid form.
10. The temperature in the outer core is around 3000ºC, while the temperature in the inner core is around 5000ºC.
