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