LAYERS-OF-THE-ATMOSPHERE education report

Layers of the atmosphere

1. LAYERS OF THE earth’S ATMOSPHERE

2. OBJECTIVES: a. Define Atmosphere b. demonstrate understanding of different phenomena that occur in the atmosphere c. identify the layers of atmosphere; and d. discuss how energy from the sun interacts with the layers of the atmosphere

3. ATMOSPHERE - is the blanket or envelop of gases surrounding the earth

4. GASES IN THE ATMOSPHERE Trace gases - include carbon dioxide, inert gases, hydrogen, methane, ozone and others.

5. Earth atmosphere is made up of different layers.

6. Troposphere makes up approximately 75% of the total mass of the atmosphere and contains 99% of the atmosphere water. Stratosphere the temperature of this layer increases with altitude.

7. Ozone Layer -it protects us from the harmful ultraviolet rays coming from the sun.

8. MESOSPHERE - the temperature in this layer decreases with altitude. -coldest layer of the atmosphere surrounding the earth. thermosphere -Comparatively closer to the sun and it absorbs a large amount of solar radiation. - The temperature in this layer increases tremendously as distance from the earth becomes greater.

9. International space station = aurora BOREALIS are bonds of light with different color

10. exosphere the temperature in this region varies from very hot to very cold.

11. Different phenomena that occur in the earth BREEZES wind that are evident near bodies of water. -they are localized winds that are experienced by those living in coastal areas.

12. 2 types of breezes - Sea Breeze- happens during the day - Land Breeze- happens during the night

13. Monsoons - wind system that involve bigger masses of air that move horizontally. -bring abundant rainfall to the country.

14. 2 types of monsoons Northeast Monsoon- dry and cool wind - The associated rainfall of this monsoon is slight to moderate rainfall. It happens from November to April. Southwest Monsoon- warm and moist wind -The associate rainfall is moderate to heavy or sometimes torrential rainfall. It happens from June to October .

15. Intertropical Convergence Zone the place where the winds from the Northern Hemisphere and the Southern Hemisphere meet at, or near, the equator. - where warm and humid air masses form.

16. a. What is the percentage of oxygen in the air? ______ b. What is the percentage of nitrogen in the air?______ c. What is the percentage of trace gases in the air? ___ d. State the names of other gases present in air.______

17. QUIZ NO. 1 Directions: Identify what layer of the atmosphere is described in the following statements. Choose your answer in the word box. TROPOSPHERE EXOSPHERE STRATOSPHERE THERMOSPHERE MESOSPHERE 1. The layer nearest to the Earth’s surface. 2. The hottest layer in the atmosphere. 3. This layer is less dense and relatively dry. 4. Meteors or rock fragments burn up in this layer. 5. The ozone layer is found within this layer. 6. This is the upper limit of our atmosphere. 7. Space shuttles fly in this area and it is also where auroras are found. 8. Clouds of all types, storms, and all types of weather phenomena characterize this layer 9. This is the coldest layer 10. The layer of the atmosphere that is immediately above the stratosphere

18. Activity 6: Breezes Differentiate the two breezes, discussed through a Venn diagram:
