Earth composition layers
WebIn this way, Earth's atmosphere can be divided (called atmospheric stratification) into five main layers: troposphere, stratosphere, mesosphere, thermosphere, and exosphere. [18] The altitudes of the five layers are as follows: Exosphere: 700 to 10,000 km (440 to 6,200 miles) [19] Thermosphere: 80 to 700 km (50 to 440 miles) [20] WebCompositional and mechanical layers of the earth (video) Khan Academy Unit 3: Lesson 1 Plate tectonics Plate tectonics: Difference between crust and lithosphere Plate tectonics: …
