CHAPTER 22 SECTION 1 VOCABULARY AND QUESTIONS

Table of Contents Show CHAPTER 22 SECTION 1 VOCABULARY AND QUESTIONS *Atmosphere- a mixture of gases that surrounds a plant such as earth. * Ozone- a gas molecule that is made up of three oxygen atoms. *Atmosphere pressure- The force per unit area that is exerted on a surface by the weight of the atmosphere.*Troposphere- the lowest layer of the atmosphere, in which temperature drops at a constant rate as altitude increases; the part of the atmosphere where weather conditions exist *Stratosphere- the layer of the atmosphere that lies between the troposphere and the mesosphere and in which temperature increases as altitude increases; contains the ozone layer.*Mesosphere- the coldest layer of the atmosphere, between the stratosphere and the thermosphere, in which temperature decreases as altitude increases.*Thermosphere- the uppermost layer of the atmosphere, in which temperature increases asx altitude increases; includes the ionosphere. LAYERS OF THE ATMOSPHERE What do you call the boundary between the stratosphere and the troposphere where airplanes fly? Which layer is where the ozone layer and jet streams exist? What will happen as you move up through the stratosphere? Does the jet stream occurs in the mesosphere?

QUESTIONS

1. Describe the composition of dry air at sea level.
-Oxygen, Carbon dioxide, varying amounts of dust and pollen, trace gases such as methane,ozone, hydrogen,carbon monoxide.
2. Identify five main components of the atmosphere.
-nitrogen, oxygen, water vapor, ozone and particulates.
3. Explain the cause of atmospheric pressure
-is caused by the weight of air molecules as elevation increases, fewer air molecules are present. Therefore, atmosphere pressure always decreases with increasing height.
4. Explain how the two types of barometers measure atmospheric pressure.
-
5.identify the layer of atmosphere in which weather occurs.
-weather happens in the troposphere.
6.compare the four main layers of the atmosphere.
- troposphere contains more of the earths atmosphere than the other layers. the stratosphere is the layer where most jet airplanes fly in. Ozone layer that absorbs the harmful UV rays from sun in this layer The mesosphere is the coldest layer of the atmosphere as altitude increases, temperature decreases. meteors burn up in this layer. the hemosphere contains the ionosphere which aids in propagation of radio signals over great distances hottest layer of the atmosphere
7. Identify the two atmospheric layer that contain air as warm as 25*C
-two atmospheric layers that contain air as warm as 25*C are the Themosphere, and the Stratosphere.

LAYERS OF THE ATMOSPHERE

THERMOSPHERE
temperature; INCREASES, 2,000*C at top 
Characteristics;
1.temps get up to 2000*C
2.air molecules are 1 km apart!

MESOSPHERE
temperature; DECREASES, -100*C
Characteristics; 
​1. protects earth from meteors
2. coldest region of atmosphere   

STRATOSPHERE
temperature: INCREASES, to about -20*C 
​Characteristics:
1. contains most of atmosphere's ozone 
​2. where jets and manned balloons have gone 

TROPOSPHERE
temperature; DECREASES, 6.5*C per km 
Characteristics:        to about -60*C
1. most weather occurs here where we live 
​2. convection currents 

MAGNETOSPHERE 
Characteristics;
1. Earth's magnetic field 
2. causes aurora borealis
            (Northern Lights)

EXOSPHERE 
Characteristics:
​1.upper part of thermosphere
​2.artificial satellites orbit here

IONOSPHERE 
Characteristics:
1, lower part of thermosphere 
2. Radio waves bounce back to 
    Earth's surface
​ 

OZONOSPHERE
Characteristics:
1. Ozone is made of 3 oxygen atoms
2. protects the surface from sun's UV rays 
3. Humans are causing Ozone depletion 

1. list the four main layers.
-exosphere, ionosphere , ozonesphere, magnetosphere
2. list the four minor layers 
-thermosphere, mesosphere, stratosphere, troposphere
3.which two minor layers of parts of a main layer?
-ionosphere and exosphere 
4.which layers is the most important to you and why?
-troposphere __ this is where we live
5.what two layers protect you?
-Mesosphere and Stratosphere 
6. which layer acts like a giant magnet? what does it attract?
-magnetosphere_ due to the field around the earth which attracts particles and keeps us safe
7. what does the air in the troposphere do as it heats up from the sun
-it gets warmer 
8. what cloud indicates the top of the troposphere ?
-cirrus and cumvlonimbus  
9.what runs along the top of the troposphere?
-the jetstream 
10. what attaches itself to this jetstream and, in a sense , tells you stratosphere begins?
​-the troposphere  

What do you call the boundary between the stratosphere and the troposphere where airplanes fly?

Which layer is where the ozone layer and jet streams exist?

What will happen as you move up through the stratosphere?

Does the jet stream occurs in the mesosphere?
