4 subsystems
Atmosphere
Geosphere
Hydrosphere
Biosphere
-It makes up of all the gases on Earth.
-It has no specific boundary but an imaginary line called the Karman line separates the atmosphere and outer space.
Athmosphere
Weather 14.5km
Troposphere
Ozone layer 14.5-50km
Stratosphere
Coldest layer 50-85km
Mesosphere
Aurora burrels
Ionosphäre
Hottest layer 85-600km
Thermosphere
Outer layer. Fartest layer
Exosphere
-It includes all the soil, rocks, and minerals present in the crust to the core of Earth.
-It is divided into three layers namely crust, mantle, and core.
crust
Geosphere
the outermost layer of the geosphere. It is made mostly of silicate materials.
Crust
2 types of crust
- OCEANIC CRUST that lies beneath the oceanic floors is about 5 km to 10 km thick.
- CONTINENTAL CRUST thicker, that makes up the continents is about 15 km to 70 km thick.
2 types of crust
- OCEANIC CRUST that lies beneath the oceanic floors is about 5 km to 10 km thick.
- CONTINENTAL CRUST thicker, that makes up the continents is about 15 km to 70 km thick.
-which lies just below the crust, is made mostly of silicate rocks rich in magnesium and iron.
Mantle
-which lies just below the crust, is made mostly of silicate rocks rich in magnesium and iron.
Mantle
-It is about 2 900 km thick.
-The _ has increasing temperatures at increasing depths.
Mantle
It is subdivided into several layers based on phase changes of minerals
and the material’s type of deformation.
Mantle
-It is composed of 78.1% nitrogen, 20.9% oxygen, 0.9% argon, 350 ppm carbon dioxide, and other components.
-It has different layers - troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
exosphere
Atmosphere
-has a radius of $ 480 km, is the innermost layer of Earth.
-It is made up of iron and nickel.
Core
-has a radius of 3480 km, is the innermost layer of Earth.
-It is made up of iron and nickel.
Core
It is comprised of two layers, the outer core and the inner core. These two regions are separated by a boundary called Bullen discontinuity
Core
-It is composed of all water on Earth in any form: water vapor, liquid water, and ice.
-It is comprised of 97.5% saltwater and 2.5% freshwater.
-It includes all bodies of water such as oceans, lakes, rivers, and marshes.
Clouds and rain are also part of the _
Hydrosphere
-It is comprised of all living things.
-It includes all microbes, plants, and animals.
Biosphere
-It extends to the upper areas of the atmosphere where insects and birds can be found.
-It also reaches the deep parts of the oceans where marine organisms can still survive.
