1 EARTH’S ATMOSPHERE

2 Composition of the Atmosphere
Oxygen= __________ Nitrogen = ________ Other gases = ________ argon., carbon dioxide, methane, helium, etc.

3 Layers of the Atmosphere
The atmosphere is divided into ____ layers.

4 Layers in the Atmosphere

5 Layers of the Atmosphere
4 Layers are: 1. Troposphere: Closest to ground All weather occurs here As altitude goes up, temperature goes _____

6 Layers of the Atmosphere
2. Stratosphere Ozone “layer” is located here Jets fly there As altitude goes up, temperature goes _____

7 Layers of the Atmosphere
Layers of the Atmosphere 3. Mesosphere: Coldest layer As altitude goes up, temperature goes _____

8 Layers of the Atmosphere
4. Thermosphere Divided into 2 parts: Ionosphere and Exosphere Aurora borealis happens in ionosphere Exosphere is considered “outer space” As altitude goes up, temperature goes _____

12 Do you understand this stuff?
Name the 4 layers of the atmosphere. Describe the chemical composition of the troposphere. What causes the temperature to increase in the Stratosphere? What causes the temperature to decrease in the Mesosphere? Where does weather occur? Describe the chemical composition of the mesosphere.

13 What is the temperature in the troposphere at 5 km?
-30 C -20 C 0 C -60 C No clue 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

14 What is the temperature at 60 km?

15 Which layer goes from 50 km to 85 km?
Stratosphere Mesosphere Thermosphere Troposphere 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32

16 Which is the coldest layer?
Troposphere Stratosphere Mesosphere Thermosphere

17 What criterion determines when each layer starts and stops?
Temperature Altitude Color Composition Prettiness

18 As altitude increases, density ________
Goes up Goes down Stays the same IDK
